Poor performance after update to Backup exec 11d

Updated to latest service pack. Version 11.0 Rev. 7170
Updated Tape driver (Performanced dropped from 1000mb per minute to 40mb per minute)
Tried HP Driver for LTO Ultrium-3 drive Ver:
Just as bad... Can't roll back to the old ones (My mistake by installing another one on top of it)

I would like to know where I can get the old Backexec LTO drivers ? Anyone know

When updating the Backupexec package I highly recommend you update SCSI controller drivers and firmware as this was the source of my problem.

Tape Drive (Firmware)
Tape Drive (Use the driver provided by Backupexec)
SCSI controller (Firmware/Drivers)


Link for HP diagnostic tool very useful in troubleshoot performace issues

Thanks, I have had a read through the above forum. There are some useful points to check and I have but with no progress. But what I have found to be particulary helpful is this tool I found "hp StorageWorks library and tape tools - 4.7"

Under the Test section it will write to your tape drive and check its speed and give its findings. I am going to check them out and see if it changes makes a change or not. Will let you know how it turns out.
