From the init messages that you had attached, I can see you
have a Sony SDT-5000 drive. This is a SCSI-2 sequential access
device and you shouldn't have any problems with it on Linux.

Most likely, your Sun workstation did not recognize the Son drive,
which is why it's reporting it as an Exabyte drive.

If the tape was written on a different system, the block size
may be different. In that case, the error you are getting may
be nothing more than an ILI error. Please try this:
mt -f /dev/st0 rewind # to rewind the tape
tar -cvf /dev/st0 "some fairly big directory"
tar -tvf /dev/st0 "the same directory"
If that works, then you have no problems with you drive. Else,
please let me know.
