OK, now I tried to clean the heads, but it doesn't make any difference.
Now this is what Patrick Kramer mailed me:

Oops, here's where the trouble gets in.
Does the disk turn if you type 'files'+chr$(13) ?
Have you tried a low-level disk program (fonito or whatever) and try
to read track 40+ or so? The least it should do is move over there. Also
try
formatting a disk.

It could be anything really, but my bet would be on the drive. Best
thing to try is another drive, but I believe the 8245 has a non-standard
connector. There are ways to connect a pc-drive though (it was discussed
here some time ago).
I don't have any information about the 8245 drive, so I can't give
you any ideas to look for on the drive itself. Maybe someone else knows
more
about this.
---------------------------
I've been researching some more on this drive, and found the following:
- If I'm lucky, I get a disk formatted with it (single sided and double
sided). Sometimes it gives a disk error, when it's writing the
bootsector, but after retrying it always seems to work)
- I can save and load files on disks formatted with this drive most of
the time. Sometimes I get Disk Offline messages. When I push a little
bit to the drivehead, it works again.
- Disks formatted with the 8245-drive cannot be read on other (MSX)
diskdrives!
- I can not read disks formatted on other drives. (I got this only once,
I think)
- If a disk (formatted on the 8245) works, it most of the time doesn't
work anymore after ejecting and putting it back in. Pushing the head a
little helps.
Conclusions: -Drive works perfectly, but the head seems to be misaligned
or something!
Can anyone tell me how I can fix this? (And if my conclusion is right!)
Grtjs, Manuel
