HI!
I'm still trying to fix this bloody drive! I found out some new strange
behaviour:

I was playing with the drive a bit again last night, and found out
this... After pushing the drivehead a bit, I didn't get Disk Offline
anymore. So I tried to save some files. It worked every now and then.
But when I tried to read those files on another MSX, I got Disk Offline
again! So i formatted the disk on that other (fine working) MSX. Then I
put the disk back in the 8245 and.... to my astonishment: THE FILES I
SAVED WITH THE 8245 WERE STILL DISPLAYED AFTER EXECUTING THE "FILES"
COMMAND!!! Yes! After a very hard low level format of the disk!! But
when the disk was back in the other MSX, it displayed no files at all. I
could even save files on that disk on that other MSX, without any
problems, and STILL the OTHER files (saved with the 8245) appeared when
executing FILES on the 8245!! The files saved on the other MSX did not
appear. One strange thing is that there would always appear a file
called "700" when executing FILES on the 8245, which I don't remember
saving on that disk... (but I could have forgotten this)...
Hmm, it seems that the 8245 is saving BETWEEN tracks or something??? So
the head must be REALLY misaligned!?
Strange...............................................
Note that successfully executing a FILES command on the 8245 still
requires pushing the drive head... otherwise it will still give a Disk
Offline error. Loading those saved files doesn't work properly, the
file-contents is corrupted... But the disk seems to work fine on another
MSX...
Can anyone explain this?
