The drive requested cleaning just yesterday which I did. I'm not sure
how old the tape in question really is. I used a dell update utility and
it updated the drive to v2181 which seems to be the latest for a
half-height SCSI tape drive. 30MB/s seems a bit low to me - it should be
able to do 60MB/s per spec. Or is that just theory vs. real world?

They are labelled 400GB/800GB - all of the same kind, so they're
definitely LTO3. The autoloader says: "Drive Idle Gen 3 Data" in it's web
interface, so yes, I'm sure.

I could check a very new tape tomorrow or try a shiny new one, just to
be sure.

Thanks so far,

Tino.
