Hi David, Hey thanks for the info on the diagnostic tools!

In my experience, drives tend to fail with errors; I've never seen one write an image apparently successfully, while introducing random errors in the data. In fact, someone correct me if I'm wrong, but don't DDS DAT drives have built-in error-correction that should prevent this kind of thing? How long are the SCSI cables? I concur with the advice to run a cleaning tape a few times, but then I would check cables and terminators and run some tests with plain dump or tar. I think HP has diagnostics for the drive, if you can connect it to a Windows machine. You might take a look at products from Granite Digital (www.scsipro.com). I used their diagnostic cables and terminators exclusively a few years ago when I was dealing with SCSI problems with a particular DAT drive - they worked great for me.

The drive is a HP SureStore DAT24.
