yeah, after i put this hdd into another computer, the apperance is exactly same, so the problem is located into the HDD or the os2 system software.
after i issue: fdisk ,first got the warning:
"The partition mapping on drive 1 maybe corrupted.
press any key"
then:STARTABLE C:Primary fat 2000
none D:Logical fat 1004
none E:Logical fat 1004
none F:Logical fat 2000
none G:Logical HPFS 10001
none
rimary unformatted 2000
none
rimary freespace 20151
It looks the partition is okay, which tool can fix this kind of problem?
next step i think i need do a clone(backup) of this disk first,
then find a tools to fix the partition problem(which tool i should use?), if cant fix, i think i need re-create all patition by hand,then copy the data back.
any suggestion will be great.
