- This sounds suspiciously like the problems I had with my first A1200 HD - I got
- it from Diamond with an 80 MB drive not long after the A1200 first came out and
- by the time the problems arose, they had gone bust and I couldn't get a
- replacement. Anyway, like you, I had bits of my drive which broke a format and
- I managed to get around most of the bad blocks by creating small partitions
- around them which were not automounted (using RDPrep - now on aminet
- disk/misc/rdp391.lha) and I was at least able to do a format. However, the
- system was never right and I frequently got write errors on some partitions. I
- then used a coverdisk version of QBTools (v1.5 I think) to map out unreadable
- bad blocks, and everything was fine for a while until it happened again. You
- could maybe try using HDtoolbox to map out the bad blocks - I suspect it would
- do a more thorough job than my old QBTools.
- Hope this helps,
- Adrian
-
- P.S. I now have a lovely new 420 MB internal 3.5" Connor HD which has given me
- no problems whatsoever.
