[Food for t
I have developed an interesting problem with one of my hard drives and can
not seem to find the solution.
I have a 2nd ST-506 hd connected (its a Miniscribe 20 meg). It has already
been formated with a FFS partition (6-611) and the CBM required (old)FS
(2-5) plus the reserved 2 tracks (0-2). Im using a CBM 2090A controller.
Recently I have had several read/write error messages. I decided to backup
the drive and reformat it. Well ive tried PREP'ing the drive, changing the
mountlist size for the FFS part. Just about everything. But no matter how
many times I format the drive - the old files are -still- there!
The PREP commands says the drive is preped, I then reboot and do a format
(not QUICK) and it actualy goes through each cylinder. However when its
done the drive is as before.
Any ideas? Please post or mail to the account below as the HD thats wacky
is my UseNet/UUCP drive :-(

Dan maybe I missed something, but are you low level formating the drive
on an IBM system? If not, low level format on an IBM system using Disk
Manager by OnTrack or a similar program, this will allow you to reformat
the first 2 cyclinders and remove the information, the format programs
for the 2090 or 2090A are not capable of doing a lowlevel format using
mfm drives...SCSIs are a different story....Mike Miller
