244.4 Secure EraseSecure Erase is a set of firmware commands available on many ATA drives. These commands areused as a secure method of data sanitization by completely overwriting all data on a drive. When aSecure Erase command is issued against a SSD, all of its cells will be marked as empty, restoring it tofactory default configuration. Unlike Disk Wipe and Disk Erase, the Secure Erase process is effectiveat sanitizing SSDs because it can access and erase all sectors on a SSD.Secure Erase is approved by the National Institute of Standards and Technology (NIST) SpecialPublication 800-88 as a method for purging ATA hard disk drives.Caution! Unlike Disk Wipe or Disk Erase , the duplicator only invokes the Secure Erase command.The actual data wiping is done at the drive firmware level. Please keep the following points in mind:• Although most ATA drive manufacturers include Secure Erase commands in firmware, not alldo. Please check with the drive manufacturer to verify that your drive model supports ATASecure Erase before attempting.• Although the duplicator can report whether the function completed, it cannot guarantee that theSecure Erase function was implemented correctly by the drive. It is recommended to check withthe drive manufacturer for verification that the data was actually wiped.4.5 Enhanced Secure EraseSecure Erase is a set of firmware commands available on many ATA drives. These commands areused as a secure method of data sanitization by completely overwriting all data on a drive. The typeof sanitization method implemented by Enhanced Secure Erase is device-specific, and may vary fromdrive to drive. In some cases, the Enhanced Secure Erase will overwrite all sectors with a predefinedpattern of ones and zeroes. In other cases, the drive has an internal encryption key which is simplydestroyed and regenerated. Unlike Disk Wipe and Disk Erase, the Enhanced Secure Erase process iseffective at sanitizing SSDs because it can access and erase all sectors on a SSD.Enhanced Secure Erase is approved by the National Institute of Standards and Technology (NIST)Special Publication 800-88 as a method for purging ATA hard disk drives.Caution! Unlike Disk Wipe or Disk Erase , the duplicator only invokes the Enhanced Secure Erasecommand. The actual data wiping is done at the drive firmware level. Please keep the followingpoints in mind:• Only some ATA drive manufacturers include Secure Erase commands in firmware, most donot. Please check with the drive manufacturer to verify that your drive model supports ATAEnhanced Secure Erase before attempting.• If there are kernel of firmware bugs, executing the ATA Enhanced Secure Erase commandcould render a drive unusable. It is recommended to check with the drive manufacturer beforeperforming this function.Other Operations |
