PARTITION COMPARE
– Compares sectors that have been copied between partitions using
PARTITION COPY. Any errors in the partition compare mode will be visible via the LCD screen.
VERIFY CHECK
– Verify check completes a read test on attached HDDs. If verify check encounters any
errors, the error will be visible on the LCD screen. Typically the error message will alert you to the LBA
(logical block address) of the bad block encountered during the test.
DISK CHECK
– Does a verify check but also writes “dummy” data to any sectors that return in error. This
can alter the HASH value (or checksum) of a disk. We recommend a backup prior to running DISK
CHECK.
SEEK TEST
– This mode does a full stroke seek test on the HDD connected to the Disk 2 port. The seek
test is done to check the mechanical integrity of the HDD. NOTE – There is no end to this test. This test
can be left running continuously and can only be terminated by pushing the POWER/START button.
DATA ERASE 00x1
– This mode completes a one-pass erase on the disk by writing “00” in all sectors of
the connected HDD.
DATA ERASE NSA
00x3
– This mode erases the data of the attached HDD by writing three-passes per
the standard established by the National Security Agency. Random data is written on two passes to the
HDD followed by writing “00” on all sectors during the third pass.
NOTE – It is possible to perform the ERASE operations on both HDDs simultaneously. If you only wish to
erase one HDD, be sure to connect the drive to the Disk 1 port.
