Tape Drive can read not write.

This drive is only about 3 months old and when tested on another machine it works. We had performance issuess with windows so we restarted the server, when it came back on everything looked good but that nights backup go 7 gigs in and then failed with a I/O error. I ran the drive utlities test and it passed the reading but failed on the writing. I did a couple of file restores to make sure the read really was working, and it did restore files correctly. We tried a new drive of the same model and it still had the problems. We shutdown the server, turned off the tape drive, turned on the tape drive and then started up the server and when everything was loaded still same issue.

What do you think went wrong?
Do you think a windows update did something to the SCSI controller card driver?
Could a new controller card just for the tape drive possible fix this?

"What do you think went wrong?"

What OS?

You may want to update the BIOS firmware on the motherboard and download and install the latest tape drive, driver.  Also, get the latest update for your backup software.

Check whether the SCSI card is identified by the Server while booting.  Check whether the read/write notch is closed in the tape cartridge

Did you try to identify and format the tapes?
Maybe even re-tension the tapes.
The server found the SCSI card when we rebooted, we were able to relabel the tape and test the read/write, it was able to read fine, just the write would fail after writing anywhere between 60megs to 7gigs.

We did add a new SCSI card and the tape drive worked fine.

I am giving pgm554 the points because he suggested a SCSI card swap, which we eventablly did.

Great, that was the next test to do. Nice job pgm!
