MAJOR HD help needed!!!

[blakjak@panix.com (Noah Mittman)]

I've tried formatting and partitioning a HD I bought just today that had
been used on a Mac previously. However, it can't seem to format it
properly - I've gotten I/O Error $027 I believe - and found that all
available space on the disk is used even though there are no files in it.
Can't erase the disk either, can't initialize it properly either.
HELP!!!!!!

Hardware: Apple II HS SCSI, ROM1 (0 upgrade), Octoram w/ 4 Megs, 1 3.5"
Apple, and the mystery drive: actually the only thing I'm sure about it is
that a) it's SCSI, b) it's 52 megs, and c) it's internally terminated and
hard-wired for ID #2.

ANY help would be GREATLY appreciated!
