AIT3 compaq SDX-700c problem tape capacity

[franck chapelon]

Hi,
I've a prb when i backup data, i can only save 60-70Go to a tape.
the HP StorageWorks Library and Tape Tools view the tape as AIT2 !!!
But this tape is a AIT3.
I've done this with fiew tape and the results is the same.

I've a compaq AIT3 SDX-700C and i use SONY SDX3-100C tapes.(the tapes are new).

Where is the prb? Normally without compression it will be ~100Go !!!

Where can i download the latest drivers for windows XP.there cannot be found easily on the net.

Please help me
Thanks for your answer.
