files or file system structures.
Non-Destructive Read/Write
Tests the disk by sequentially reading blocks on the disk, writing test data to the block, checking
that the data was written successfully, and then restoring the original data to the block. If bad
blocks are found, see above.NOTE: The device should be connected to a UPS or data may be lost
due to power failure.
Destructive Read/Write
Tests the disk by sequentially writing test patterns to each disk block and checking that the data
was written successfully. The last pattern written is 0's that should trigger the bad block
relocation or remapping feature of the hard disk so this may correct some or all of any bad blocks
on the disk. A follow up test can be used to see if bad blocks have been fixed. NOTE: THIS
WILL OVERWRITE THE EXISTING DATA ON THE DISK.
Maximum bad blocks to find
The disk check will stop when this number of bad blocks has been found. If set to 0, the entire
disk will be checked. It is often useful to set this to 1 since even 1 bad block means the disk is
having problems and there is little reason to continue checking. Small numbers of bad blocks
may be corrected by triggering the disks bad block relocation or remapping feature by erasing the
disk or running a Destructive Read/Write disk check on the disk.
Erase Disk
Begin/End
Erases the first and last 100MB of the disk. This can be useful to remove bad partion tables or
raid meta data. NOTE: THIS WILL OVERWRITE THE EXISTING DATA ON THE DISK.
Entire Disk
Erases the entire disk. This can be useful to cause the disk to relocate or remap bad blocks on the
disk. Note: this is not a secure erase, it simply writes 0's to every block on the disk. NOTE: THIS
WILL OVERWRITE THE EXISTING DATA ON THE DISK.
