Backups seems to work, but verify fails in 3rd set. We can read files from
the backup. The problem appears to be consistent now after having done 6
or so backups seccesfully in a row previously. We have Benchmark DLT 1, Symbios
875xsid (or similar) controller. We are using latest symbios drivers, Windows
service packs and your Benchmark drivers. The drive goes offline and has
to be set offline then online again to re-enable it.

We are completely stuck as to how to fix this and any thoughts would be greatly
appreciated.

many thanks,

Angus Tyler
