SCSI may very well be low-level formatted.
No, not anymore. Older SCSI hard drives allowed this, however. So in this context, the LLF might have been on topic.
It worked, and IIRC SCSI drives may be low-level-formatted, which IDE would not allow in the old days.
New SCSI hard disks can't be low level formatted, either. The old IDE hard disks could be low level formatted, but that only rendered the HD unusable. New IDE HDs ignore low level format cmd completely.
Though on the other hnd, it usually doesn't get you anywhere, unless in a very few cases. I always used "verify drive" in combination with low-level format because I thought there driver errors.
That's true, the low level format can't really fix the damaged disk. The disk might appear working for a moment, though. But LLF can't magically fix physical errors.
Also, if you abort the Low Level Format, the disk might ignore any further LLF commands, rendering the disk totally unusable.
So yes, you can low-level format SCSI drives, but most of the time there is no need to so.
You should only try this for old SCSI hds, when nothing else works. If the disk is giving physical errors, you should rather replace it.
See
Hard Disk Formatting and Capacity and
Low-Level Formatting for details.
Basically this means that the Low Level Format offers no real advantages and users should be advised not to try it, at all.
