after entering the rest of the command. In the example below, we instructed the drive to clear the GLIST, use defect

format #4, and set the interleave factor to 2. To repeat an earlier warning, if you do not know what all of this means,

you should probably not be doing this. We strongly recommend contacting your storage vendor to determine whether

or not a special format command should be sent rather than the default.

Do you want to assign a custom (non-zero) defect list format or assign vendor-unique settings? <Y/N>: y

Please enter the last 5 bytes of the FORMAT UNIT CDB in hex. If you don't know what they

should be, then it is highly probable you should NOT be sending vendor-unique info.

CDB[0] = 04

CDB[1] = 0B

CDB[2] = 00

CDB[3] = 00

CDB[4] = 02

CDB[5] = 00

Will send CDB = 04 0B 00 00 02 00

Are you sure you want to do this? Answer "YES" to begin the low-level format, anything else exits program:

Low level formatting aborted. Program exiting now!

Formatting Disks in the Background

If your disks were made after 2005, then chances are good that they support background formatting. This command,

-formatb, lets you issue the format command to a device and the selected disk formats in the background. The net

result to the user is that the program returns immediately. If you combine the -formatb with the -confirm

command, then you can format dozens or hundreds of disk drives at once, with no host computer overhead.

Background formatting makes a lot of sense if you have (JBOD) enclosures and a large number of disks that need to

be reformatted.

***************************************************************************************

* Warning: You have instructed the software to reformat the selected disk. No checks *

* will be made to verify that the disk isn't mounted or in use in any way. *

* (Although reformatting your boot disk will blow the O/S, it will work.) *

* *

* The process could take several hours to complete, and this program will *

* lock up until either the formatting is complete or the drive rejects the *

* command. Once the command is sent to the device, the software will *

* suspend and wait for the action to complete. *

* *

* Your operating system may attempt to query the disk unless you have *

* unmounted it (unassigned drive letter in Windows, umount in UNIX/LINUX). *

* *

* As a formatting disk is going to appear dead to your operating system, *

* you may have to endure some error or system log messages, or even force *

* the system to rediscover devices after the process has formatting has *

* been completed. WARNING: If the formatting is interrupted due to *

* a power failure or an external hardware/software problem, then you must *

* reformat the disk as this is the only way to recover from an incomplete *

* format. *

* *

* If you are formatting a disk as part of a disk drive firmware update and *

* drive cloning procedure, don't forget to also clone the mode pages *

* BEFORE reformatting, as the disk topology (sector sizes) and defect *

* layout are defined in the mode pages and used by the disk as part of *

* the formatting process. *
