I recently acquired a Sony 3.5 inch double sided drive , that I have added
on to my 520 STFM. The connecting cable I made using the pinouts given in
the back of the Atari manual for the external drive. The drive works to a
certain extent, I cannot format it using the built in TOS formatter at all,
I can however format a disk using DCformat. With a DCformatted disk I can
write to the disk, but not consistently, write errors will crop up. The drive
works perfectly on two other computers I have kicking around, these are non
atari computers though, but the drive does work flawlessly on them.

Has anyone out there used a Sony MP-F63W-33D drive as a external drive and
had good results ? I would appreciate any info anyone has about this problem.
I know that other people have attempted to add on external drives and had
varying results, any suggestions as to a drive that will work ?

I am somewhat perplexed as to why is doesn't work, the drive is about as
standard as you can get. Incidently it will not work at all replacing the
internal drive, and as a externally connected drive can read any disk
I currently have.

Thanks
