If I change the block size won't that prevent me from reading from the tapes 
I've already written to?

tuning guide it talks about the block size of your scsi adapter.
It says that a XXXX type of tape drive does 1.8MB/sec at 32K block size and
15MB/sec at 256K block size ( I don't remember the numbers but the point is
clear). Check the method of testing the block size in the registry in the
tuning guide. I think it is right at the end of the guide just before the
index.

Can't get my HP Ultrium drive to backup any faster then 1.2MB-sec. I've
update the firmware and drivers for the drive and SCSI controller (39160).
I'm backing up multiple streams from the local server and a couple of
clients with a Gig NIC set to GB Full duplex. Have tried just backing up
data from the local system from two drives and a RAID system.

I even used bigasm (discribed in the NW tunning guide).

O/S is WIN2K-sp3
NetWorker 6.2.
2-1.4GHZ CPU's
2GB mem

Any idea's ????
