I've used SCSI tape under Linux and other Unixes, but not scads. First thing I'd try though is cleaning the drive (use a cleaning tape), second would be trying a second media unit to see if maybe there was something wrong with the tape. Third, I'd find someone who knows more about tape processing and drivers than me to diagnose any remaining problems. -- Karsten M.

Is the read/write head clean? Is the tape ok, or has it worn out? Is your SCSI bus clean (i.e. properly terminated, cable within max. length, etc.)? Is the drive ok? Too many questions, but you need to answer them before we can help. -- Sign the EU petition against SPAM: L I N U X .~. http://www.politik-digital.de/spam/The Choice /V\ of a GNU /( )\ Generation ^^-^^
SCSI tape errors
Hi i have set up a SCSI DAT tape onto debian slink with kernel 2.0.38 and nfs (no_root_squash) mounted an IBM AIX directory. I use a simple backup program which tars the files from the AIX directory onto tape. It works for a little while but i think it gets into trouble when it trys to proccess a large file (200MB).
