*snip* Thanks to everyone who replied! Well, a while after sending the mail I found the model number faintly written on the back of the drive and after browsing HP's website for a while I found some information on the dipswitch settings.
So, as Kevin suggested, I dug out the screwdriver and opened it up. And I am sure you can guess the picture, yup, it was set with hardware compression on and no host control. So I flipped it to default off with host control on and ran tapetype again and got a lot better numbers this time. Conny
