It was designed to store information in such a way that it cannot be easily modified, changed, or accessed by the user, BIOS, or the OS. SATA SATA is an evolution of the Parallel ATA physical storage interface. SCSI Short for Small Computer System Interface, a parallel interface standard used by Apple Macintosh computers, PCs, and many UNIX systems for attaching peripheral devices to computers. Secure Erase A way of erasing ATA or SATA hard disks using internal HDD commands. This has the benefit of overwriting remapped sectors too.Before you start using the Blancco Client software make sure that all files, folders, software applications or any other information that you want to save for later use are backed up on an appropriate media device other than the original hard drive. If you are not sure whether to erase the information on the hard disk, please contact your system operator, information management or a corresponding party, which maintains the computers in your organization. For future use of the erased computer an operating system must be installed. Data that has been erased from the hard disk by this program cannot be recovered by any existing method. Please note that Device Configuration Overlay (DCO) settings and the Host Protected Area (HPA) will be reset to the default settings during the Blancco software boot. Every erasure uses one license (when using PC-based licensing) so you want to erase all the hard drives in one run. If you have a laptop computer plug in the power adapter. There may be problems when erasing a laptop on battery power. Disable or type the BIOS passwords requested during the booting up. This means the passwords that some computers require even before the actual booting starts. Other kinds of BIOS passwords do not usually prevent erasing the hard disks. Disable power saving qualities from BIOS. Note!http://goldengatetaichiqigong.com/userfiles/first-years-manual-breast-pump.xml This step is usually not needed, but some hardware may have problems if power saving is enabled, so if you have just one license it is prudent to do this. In recycling centre or corporate environment this should be done only if there are problems with the given computer model when the power saving is on. If your Blancco software is in.iso image form, burn it to CD. Switch-on the computer power, put in the Blancco CD and boot the system from the CD. Read section “Changing the boot sequence and accessing BIOS” for further info. Follow the user instructions in order to start erasing the data. Double-check that all hard disks have been detected correctly, because this is needed to erase all the data from them. Note! By default Blancco PC Edition can erase up to 4 hard disks, one at a time. Blancco Server Edition can erase up to 16 hard disks simultaneously and Blancco Data Centre Edition can erase up to 256 hard disks simultaneously. In this manual BES and Blancco Erasure Software are used interchangeably. Please check that the hard drives have been correctly identified. If a hard drive contains partitions, you are able to select and deselect them for overwriting with a keyboard or by clicking them with mouse. Selected partitions have red background in the user interface. Note that all hard disks are selected for erasure by default when the software starts. Start the erasure by clicking erase with the mouse or press tab-key until erase is selected and press enter. You will be asked to confirm the erasure before it starts. If you are erasing a hard disk and erasing remapped sectors, the red font means that remapped sector erasure is not supported. Progress bar and time left indicator show how long it takes before the process is finished. You can click ESC to exit the software before the process is completed, but then the hard disks are not fully erased and Blancco cannot guarantee that no data remains in them. Also, you will not be able to see the erasure report if you exit the software before the erasure has finished. If you click quit you have to confirm the selection; After saving the report or after pressing “yes” to confirm, the “please shutdown the computer” screen will appear. Note! Save and store the original erasure report. The software overwrites every byte of data on the hard disk, in a way defined by the overwriting standard or a user-selected pattern. Following format methods available: FAT12, FAT16, FAT32 and NTFS. This is due to the fact that NIST based standards use firmware based erasure commands that do not support erasure of specific parts from the hard drive. Editing the erasure pattern Select “custom” from the standard list. Enter the number of overwriting times and press “define”. This gives access to modifying each overwriting method. The options are random or mask. Random means randomly selected binary 1 or 0 and with mask you are able to select the binary pattern, which is shown as Hex form. In addition, if the reports have been modified with another tool, they will no longer be shown in Blancco Clients. This is a precautionary step by Blancco in order to verify that the report is authentic and has been generated by Blancco software. Both take some time and report hard disk health status. Warning! Do not turn off the computer or cancel the repair process or the SCSI disk can be damaged. Select the license code file from the USB and click it to add erasure licenses to the HASP dongle. The activation key request should contain the ID of the HASP key and the types of the client software and the number of licenses for each type. The activation key file will be sent by email or other agreed upon means and your account will be charged with the licenses offered in the activation key. These are the steps to update the HASP licenses: 1. Save the activation key received from sales representative or blanccoservice.com to USB 2. Plug the HASP dongle and the USB drive with the activation key file into the computer where Blancco is running 3. Click on ACTIVATE on the dialog that notifies about license insufficiency. License of the used product is taken immediately after you have started the erasure. Note! Make sure the HASP key is connected and if the activation is successfully done, the license information displayed at the top centre of the screen will be updated and if enough licenses were acquired, further operations will be allowed. The status of each erased disk (erasure completed successfully, with errors, with exceptions or with errors and exceptions) is written, colour coded so that the result is easy to see. Green text means that the erasure was successful. Blancco’s erasure products will produce reports in four different forms. Html format can be viewed in a browser. All xml and csv formats are provided in order to facilitate data importing to external database systems. These files contain all the reports, which are generated by the erasure software. The folder structure contains the xml, xsl and css information for individual reports. Xml information always contains the actual hardware information while the xsl and the css files are just for generating the report style and structure. The all.xml -file can be uploaded to the Management Consoles and blanccoservice.com as one single file. Blancco client version 4.9 allows up to 500 erasure reports to be saved on a single USB stick. With this addressing the hard disk is divided into smaller parts that can be appointed according to certain parameters. In magnetic media the mentioned physical parameters are sectors, cylinders and heads. During the computer usage these parameters enable the operating systems to locate the information on a hard disk but they also define the size and storage base of a hard disk. A reliable and protected detection of these hardware level parameters is essential and the erasure software must be capable of detecting the correct hard disk sizes regardless of the techniques used in altering the hard disk information. Failure in accurately detecting the hard disk may result in an incomplete erasure of the hard disk. All Blancco data erasure tools utilize hardware level detection for hard disks enabling the software to detect correct hard disk sizes regardless of faulty or incorrect BIOS set hard disk values. As a result, the overwriting process will reach the whole hard disk surface leaving no areas untouched. Bad sector handling Even though the incorrectly configured, faulty or damaged configurations cause a potentially remarkable data security risk there are also other gaps that need to be addressed in order to guarantee a secure data erasure process. Hard disks might contain damaged areas that cannot be accessed with read nor write commands anymore, which makes those areas unusable. In data erasure terms these areas are called physical bad sectors and data erasure tools must be able to detect and especially report them. Blancco erasure client keeps track of the data erasure procedure and informs if the data erasure (overwrite) cannot be performed due to some error on the hard disk. E.g. in case there are any bad sector(s) found on the hard disk, the software will try to write a data block to the defective area. If the area remains “silent” Blancco will try to write a smaller block (half of the original block size) to the defective area in order to overwrite the maximum amount of data. The same procedure will continue until the software tries to write the smallest possible block to the hard drive and if unable to do so the sector will be marked as physical bad sector. One of the possibilities is sector remapping. This allows the hard drives to detect and hide the sectors, which will either be or have become impossible to access. The hard drives have a so-called spare area intended precisely for this. When a failed sector is detected, the hard drive controller assigns the address of the sector to a new one in the spare area. So the address remains the same but the owner is changed. The remapped sector may contain some of the user's data. With Blancco Clients the remapped sectors can be erased. Disable the BIOS hard disk detection when using Remapped Sector erasure. In many computers the remapped sectors can be erased even without changing BIOS settings, but by disabling the BIOS hard disk detection some problems can be avoided. If the remapped sectors are detected during the erasure processes the following text appears to the progress bar: “ESE Running”. Note that if “Extended NIST 800-88” erasure method is selected the Remapped Sector Destruction is performed to every hard disk. Erasing remapped sectors can be a time consuming process depending on the hard disk size and disk speed. The whole hard drive will be erased. If you want to erase just a partition, do not select one of these methods. The HPA is commonly used to store the recovery part of the operating system and can contain sensitive data. When a Host Protected Area is found the area is erased as a default. Pop-ups are shown only if problems are occurring or the erasure software has been modified to allow the user to select if he wants to erase the HPA area or not. Note! In order to guarantee the functionality of this option, please disable the BIOS hard disk drive detection for proper detection and execution of Blancco. In some cases the computer must be rebooted in order to remove the HPA. Device Configuration Overlay (DCO) Device Configuration Overlays (DCO) is another but less known optional feature set. It first appeared in the ATA-6 standard and because of this it does not have as many features as HPA. DCO enables the possibility to create special partition to hard disk where the user or operating system cannot access. This specified part of the hard disk creates a risk that some data might be left on the hard disk after the erasure unless the erasure product is capable of detecting and also extending and erasing DCO areas. Blancco erasure client products are able to detect, extend and erase DCO areas. In addition Blancco software reports the procedure to the user in the user interface and also in the erasure certificate. Q: Why doesn't Blancco over write this area. A: There is a BIOS low-level protection mechanism that locks DCO functionality and prevents disk configuration changes by some malicious software. The protocol is there, but the software cannot access it because the BIOS is blocking the access. Q: Is there a way around the DCO. A: If there is a DCO configured extra partition on the disk and BIOS freezes DCO functions then normally the freezing lock can be switched off from the BIOS settings e.g. turning off the hard disk detection. It is also possible to connect the disk to another machine with the required functionality to remove DCO. If there is no way to disable the DCO freezing lock it may be that there is a BIOS protecting mechanism against setting or removing the DCO partition. This usually means that there is no extra partition and the message “Unable to access DCO feature set. The last column specifies the needed actions for accessing the complete hard drive area. For instance HPA is not supported in SCSI standard. 2) YES; unless the DCO is in “freeze lock” mode. Erasure verification All Blancco erasure methods verify that the erasure was successful after the process is done and the results are shown in the report. However, for added security the user of the software can use Full Verification that reads the whole hard disk, to make sure that no data remains. Please check from your sales representative what features are included if you are not sure. 5.1. Hardware tests Blancco erasure clients can contain an inbuilt hardware test application. The application can perform up to 9 different test features for the hardware. The purpose of these hardware tests is to ensure the functionality of different computer components. By performing the tests the user is able to check and report the current condition of a computer. Hardware tests include both fully automated and manually operated tests. Manually operated tests are based on visual and audio output that the system provides. Note! This option requires a modified software image from Blancco. Other than automatically operated tests could be performed before or after the erasure. Automatically operated tests The following hardware tests are executed automatically before the Blancco software has been completely loaded to the computer. The user will see a progress bar on the screen for each test component. The testing process can take a while. If there is no time for performing the tests they can be skipped by pressing. Memory test The memory test checks the low and the extended memory of a computer automatically. The test time depends on the size of the memory and the speed of the processor. The results of the test can be either operational or failed. The tests are operated with certain data patterns. Each data pattern is first written to the memory and then read and verified. CPU The CPU test checks the functionality of the processor. The CPU test is performed automatically and the test results are either operational or failed. Different components of the pointing device are then shown on the screen. When a component passes the test the colour of the corresponding rectangle changes colour on the screen. The pointer position is shown in x- and y-coordinates. After clicking on each rectangle the colour of the target rectangle changes to red. Actions listed above can be performed in any order. Clicking a rectangle or button, which is already red will not change the colour back to grey. When all the rectangles are red the test is over. The pop-up screen will appear and the user must confirm the test result. The software displays several test screens for the user. First the user should see 5 different screens with different colours. After that the software displays a test pattern. Some of the test pattern lines are two coloured. If a two coloured line is shown as one continuous line the display is functioning correctly. The picture on the left is one of the colour test screens. The middle picture is the confirmation screen where you have to confirm if you where you able to see the blue colour. The picture on the right side is the test pattern picture. Please answer “Yes” or “No” to the questions. If the test screen is not shown correctly there is an option to re-run the test screen, abort the hardware test altogether or proceed to next screen. Please answer simply with a “Yes” or “No” to the validation questions. The display test can be aborted by choosing “Cancel”. The keyboard test is performed manually. Before the actual test the user is able to choose the desired keyboard layout (see the picture below). The keyboard layout is shown in small rectangles on the screen. When pressing a key, a corresponding rectangle turns to red on the screen. Releasing the key will not turn the colour back to grey. The response time for key press detection is short. Short response time allows the user to press the keys very fast e.g. dragging the finger over the keyboard or pressing several keys simultaneously. Please note that most of the keyboards can send only 3 key signals at once. The indicators should be blinking for a while. In the first case the software will perform both writing and reading tests of the optical drive, and in the second - the reading test only. User can download CD or DVD images from the from the following location: Floppy drive The floppy drive test is used to test the functionality of the floppy drive. The floppy test tries to read the floppy from random locations. The floppy test does not need any special test floppy. If the floppy test is a success the system proceeds automatically to the next phase. If the test fails the user has the option to repeat the test or continue to the next phase. Sound The sound test is used to test the functionality of the PC speaker. The system produces a beep sound and asks the user if the sound was heard or not. The basic sheet contains fields for extra information, which can be filled in before saving the report. These fields are located at the end of the report and the fields are named as info1, info2, info3 etc. Also the list of installed software is shown. In the software list the name of software is always shown. Version and serial are shown if the software’s manufacturer provides them (see the picture below). Configuring Putty PuTTY is an open source xterm terminal emulator that provides support for remote controlled printing. It is a multi-platform program that runs on both Windows and Linux. There are several ways to enter the setup depending on your computer manufacturer and the model. As the message flashes only once on the screen, you must be quick to press the key before the boot sequence continues. Please note that the boot sequence may continue without any user intervention. On most systems you need to press these keys repeatedly during the POST (Power On Self Test) as soon as the computer has been turned on. If the Windows Logo appears, you are too late, restart the computer and try again. An ISO file is a image file which contain many smaller files that must be extracted to the CD at the time of burn. By performing the burn process properly the ISO image will create a possibility to boot your computer from the CD. Nero: Burn Image to Disc Roxio: Burn an image ISO file with Creator Classic ImgBurn: How to Burn ISO Recorder: Recording ISO files Using a non-graphical user interface Blancco clients will use a non-graphical user interface if the display controller does not support VESA VBE 2:0 (Video Electronics Standards Association driver) or 256 colours and 800x600 resolution. Most of the display controllers, however, support these features. Using a non-graphical user interface not difficult. It has been built in to include all the same functionalities as the graphical interface. You do not need to use any special text commands etc. If the mouse is attached, it will also be supported. Note! The non-graphical user interface supports only English language. If you want to access the non-graphical user interface manually you have to press both shift buttons down before the software tries to start from the boot media. Gathering this information before contacting support will greatly speed up the trouble shooting process. Continue by pressing “OK” without doing any changes to the driver list. 4. Blancco client software starts loading the drivers and you should see the driver names as clear text. The most common ones are listed below. In other words data has been corrupted. New copy of Blancco (e.g. download the CD image again and check the size) Output: Description: Not enough low memory Not enough memory under the 1M area. This usually means that extended bios data area (XBDA, EBDA) is too large. A broken BIOS clock can lower the resale value of a computer. Blancco software uses the following method to determine if the BIOS clock is broken or not: the software informs the user that the BIOS clock has a defect if the date detected is before 1.1.2003. Erasure can be cancelled or can be continued ignoring the deficient BIOS clock. This feature is no longer supported in the v4.x product family. Please insert a separate floppy, which is formatted and is not write protected into the floppy drive. If needed the report can be saved also to a USB stick. Skipping loading modules that cause the system to freeze In some systems drivers can cause loading the software to freeze. Most often there is a problem with USB drivers. It is possible to skip loading the modules, which should remedy the problem. The dismantling feature is not supported in some RAID adapters and the hard disks are handled and overwritten as logical arrays. From arrays we can’t get the serial numbers of the individual hard disks and therefore the erasure report will not give you valid information. Warning! Blancco does NOT recommend performing erasure in arrays due to a fact that we can’t report which physical device has been erased. The logical arrays that are overwritten must be complete and intact. This parity hard disk acts also as back-up data storage. The most important thing is that the data area is overwritten also from the parity hard disk. If the replacement hard disk has not been initialized as part of the array it will normally not contain any data unless it has been used earlier in another hardware configuration for saving data. A system partition for RAID information within the first hard disk of a logical array will not be erased since the RAID controller does not enable it. For instance, some RAID adapters contain a meta partition in the beginning of each logical array that contains only RAID configuration data. Erasure of the meta partition can be carried out by attaching the hard disk pack directly to external SCSI controller. After that the RAID controller has been bypassed. In such situation the user needs to select only the normal arrays for the erasure and reject I2O arrays. For the eXtremeRAID 1100, firmware version 5.06-0-52 or higher is required. For the AcceleRAID 250, 200, and 150, firmware version 4.06-0-57 or higher is required. For the DAC960PJ and DAC960PG, firmware version 4.06-0-00 or higher is required. For the DAC960PU, DAC960PD, DAC960PL, and DAC960P, either firmware version 3.51-0-04 or higher is required (for dual Flash ROM controllers), or firmware version 2.73-0-00 or higher is required (for single Flash ROM controllers) Blancco Data Centre edition is the first Blancco data erasure product that is directed to enterprise scale data storage systems. Blancco Data Centre Edition enables the user to perform certified and 100 secure data erasure for directly attached storage enclosures or hard drives through supported host bus adapters. One of the strengths of Blancco Server Edition is the dismantling feature and it ensures the secure erasure of the entire data surface in all functional hard drives. Functionality of this feature is to break RAID configurations and erase physical disks separately. Blancco Server Edition communicates directly with the RAID controller and removes the RAID configuration information. This functionality enables the individual detection of all hard drives (including HDD names and serial numbers). Important! When erasing RAID as logical arrays, disks behind the RAID controller still contains the RAID configuration information. If you run into such configuration, report it to Blancco and try one of the following suggestions: 1. Attaching hard drives to an integrated SCSI port on a motherboard Normally, the RAID adapter is the reason why hard drives are not detected. In these cases the fastest solution for erasing the hard drives is to bypass the RAID adapter. Most server computers contain either an integrated SCSI port on a motherboard or an additional standard SCSI card. By attaching the hard drive cable to the SCSI port instead of the RAID adapter the hard drives can be detected without any limitations. This operation also allows an individual detection for each hard drive. Normally, server hard drives use an easy removal mechanism and hot-plug support. This allows the user to easily remove the hard drives without opening the server covers. All the detected hard drives can be erased without limitations. Requirements for storage system data erasure 1. Direct access to the physical hard disks through supported Host Bus Adapter (HBA) a. X86 processor based server b. Supported Host Bus Adapter c. Native hard disk connection to the hard disks or to the hard disk enclosure 2. All active devices (disk processor enclosure or disk controller units) that operate between actual server and hard disks should be bypassed. This chapter describes roughly the data erasure process in EMC specific storage system environment. Count the drives listed on the software to make sure all drives are detected. 4. Choose overwriting method. 5. Start Erasure. 6. You will have to perform this on each BE loop one at a time. Some servers are using different processor architecture and cannot be erased with these software products. Blancco SPARC Edition can erase Sun SPARC based servers. Servers built on other architectures cannot be erased with the Blancco Erasure Client. Most of these servers are reserving a lot of space and moving them around can be challenging. In addition, there could be many hard drives thus making it inefficient to physically remove the hard drives and erase them in another hardware configuration. As a solution, the hard drives can be connected to a supported x86-based machine (erasure station) and erased without the need to remove them physically from the original configuration. The picture below describes how the hard drives from the RISC-based server have been connected to the x86-based server. Note! Note! Starting from version 4.8 Blancco started to support alternative sector sizes including 520, 524 and 528. Enquiries sent during the weekends will get responded to within 72 hours.
