Although I can't tell you what the thing is that makes DiskExpress 1.05
a killer, but it is that for a fact on the newer harddisks. After
running DE 1.05 on my internal Mac SE drive, Disk Repair would report
an error (but I never lost files, let alone an entire harddisk). Someone
told me the problem lies in the fact that DE 1.05 doesn't update the
'second catalog' (or something like that, i'm not technical ;).

Even though it doesn't help you right now, get a hold of a later
version of DE. DE 1.06 has been out some time and friends of mine
have received their 1.1 update. Version 1.06 I've run before, after
which Disk Repair reported no errors.

Because I don't think DE can cause _physical_ disk damage, you
should try a low (I mean loooow) level formatter.
