[comp.sys.atari.st] Disk Drive Problems

MLS@s40.prime.COM (10/26/88)

Help!

The internal drive on my 1040 will no longer read any disks formatted
with 10 sectors per track.  I can format new disks in this manner and
it will read them fine, but not any previously written.

Disks that will not run include an original copy of SSI's "Heroes of
the Lance" which uses this format.  As this must be an autoboot, I can
not run it off of my second drive.

I brought the drive in to an "authorized service center."  They held it
for nearly a month, and then returned it at no charge, claiming that
they were sorry they held it so long.  When I got it home, it still
didn't work!

I have now brought it to another service center and explained the
problem.  He's not sure, but he doesn't think that ST Drives are
supposed to handle 10 sector tracks (in the same way as tracks 81
and 82 are no longer supported).

I figured it was an alignment or timing problem, but this appears not
to be the case.  Does anybody have any suggestions???

Thanx in advance.

Hi all.  I am having problems with my (double sided) disk drive on my Mega 2. 
Whenever a disk starts to get full (above 75%) it starts to randomly trash
files, making them unreadable.  Even though I have an unreadable file on my
disk I can save a new file to it that the computer can then read later.  I am
using the standard Atari 720k format, but using other formats does the same
thing.  Anyone have any ideas?

Maybe the drive head is out of alignment.  Take it to an Atari dealer 
if you have one near you.
