A SCSI (disk) device is reporting a write failure.

Tape drive error.

You have an Exabyte tape drive?

*Might* just be a bad tape.

yes my friend I have EXABYTE drive.
what can I do.

change the tape or use a cleaning tape?

What model Exabyte is it?

Some tape drives will tell you when they need a cleaning, many won't. If not, you should clean it after a certain number of uses, depending on the type of drive. (Or perhaps "once a month" if that's close enough...)

Do you get those error messages every time you use the tape drive, or just with one tape? If it's only with one tape, obviously throw that tape out.

Also - many people back up to tape but never bother to test their tapes. It's worth checking occasionally to see if your tape backups really do work. (Carefully! You don't want to accidently restore old files from a tape over newer files on your disk drives.)
