comparing this tapetype to the last ibm drive (that broke and was replaced by
this) the speed is nearly half.

This brings me to another question - what could be causing this ?
The system itself has not changed, nor has the cabling, really. unless the
cables have become damaged (or the scsi card inside the machine is now having
problems), what else is to check?
Theoretically, this new drive should be as fast if not faster.. but it isn't.
At least it seems to *work* now.
