I 've done the strace, but my poor knowledge prevent me from analyzing it correctly so as recommended by Corinna i've attached the trace file.
thank you for your help. Cyril.

Today's tape code in Cygwin still works nicely with standard SCSI tape drives, as long as the Windows driver is the right one for the drive type. Just for clarification, the tape code in Cygwin doesn't use any low level access, just plain high level Win32 tape access functions. Are you using the "DAT 4mm" driver or whatever the name is? The bottom line is, I can't tell what's going on with your tape drive. You could run the above command under strace and send the output as a bzip2'ed attachement to this list. Maybe it helps to find the cause of your problem.
