1) What's the physical number of bytes a DDS-3 tape will hold uncompressed,
it says 12gig, but I cannot put more than 10gig on one tape without spanning.

2) Is there a way for BackupExec to tell you how many tapes your data will
occupy, I prefer not to span tapes to avoid long restore times.

3) Also, it says my tape drive (seagate dds-3) does 132meg/min - but I can
only get it to do 53meg/min, using a Adaptec 2940UW scsi card. Do I need
faster scsi card ??
