Hello,
I'm having the same problem.
Replace my scsi tape drive for a HP Storageworks DAT40 USB internal drive, windows 2000 server recognized it very well, nt backup can work with it.
Veritas Backup Exec 9.0, updated to 9.1 included the last hotfixes/patches/servicepacks, but it will not recognized my tapedrive.
The driver I must use(found on the internet) is the correct one. Disable the Remove Storage Service isn't the solution as well.
So please, help me !
