Hi again,

Did the test with the disk with problems - and the exact result:

ibcmd ERROR
ibsta=&Hc170 < ERR TIMO CMPL REM CIC ATN >
iberr = 6 <Op. aborted>
ibcnt = 0

I then retried with the no-timeout option enabled. Worked like a charm - 
copyed the whole disk! The old version timed out.
(it's still creating these funny files: I'm asking it to do c:\diskette, 
which it does. Size=4166 bytes, and I also get an F82 file in current 
directory, which has the correct size and is the file that contains the 
image. Not a problem at all, not that I know it, but funny :-)

AND this new version allowed me to rescue the disk - fantastic! I'm 
really happy about that! Thanks!!

I'll be checking out 4040 asap.

Cheers
Claus
