Yes, I have had many of the same experiences with the Seagate Travan 4 GB drive.


You might get some joy using scsiadd to delete and readd the device. 
Or, it might not see the drive when you try to readd it.  No harm, since 
otherwise you can't use it again anyway until reboot.


Often, I have decided that a particular tape is bad, causing the 
problems you're seeing, only to find that a retension, plus starting to 
write at the beginning of the tape again clears everything up.  Once the 
tape screws up, you can pretty much forget about continuing to append.


I've had better luck with some IBM OEM Travan drives that I got off EBay.

I have heard, and experience confirms, that some of the drives don't 
have very good motors, and you can tell if you hear the drive continue 
to reposition multiple times when you put the tape in the drive.  It 
should try once and be through.  If it's doing this, maybe you could 
return the drive and maybe hit on a better one next time.

I've got a few of those 10/20's here.. Unreliable drives.. But nowhere
near as bad as the HP 14gb models.  Those will die every year or so, no
matter waht kinda use you put them through.

Replacing slowly with DDS-3/DDS-4 drives.

Do they work better with the 2.4.x or 2.2.x kernels?  Are you able to
get them to work until they croak?  The drive has not been used that
much at all, due to these issues.

I don't run 2.4's here, cause I'm still using potato.

Most of the machines are running with ide-scsi, due to Andre's IDE
patches being installed.  Seems to work about the same as regular IDE
mode does.

Once they're setup, they do seem to work till death, haven't seen any
major issues.
