I try to use MHDD - MAKEBAD. How to UNDO MAKEBAD in case of mis-entry?
Does ERASE (LLF) command also remove all "BAD" mark by MAKEBAD?

How to automatically put put Error and Warning LBA to defect list or marked bad automatically, instead of saving to disk, and manually MAKE BAD one by one?

Could I skip bad sector in some beginning sectors (starting from 0)? Since the result of SCAN show there are bad sectors in beginning and ending of the disk (old Seagate 2.1 GB).

I also have 40 G Maxtor and 10.2 G Seagate BAD hard disk, but why can not be accessed to by MHDD. Seems there is strange sound while powering up, like spindle/motor does not want or hard to go.

Thanks.
