I had a similar problem with my DLT4000 drive. It was caused by unsuitable
media. Although the tapes seemed to be suitable for DLT4000 drives there
were preformatted in some kind; I bought tapes from diffferent
manufacturer, and they do fine.

I studied the documentation of my drive which explains the "Vendor
Specific ASCQ" im some way so that I got the idea to use other tapes.
