Any answers are welcome. > HP has buried on their technical support web site a list of all of their tape drives and what the little switches on the bottom are supposed to be set to for various Unixii. The tape drive is probably jumpered in some weird mode - if I remember right Solaris likes everything on it's SCSI chain jumpered at fixed 512-byte blocks, which is a real pain in the ass when attempting to put a CD on a Sparc. (since few CD drives have the required jumper on the back) Also, a lot of those 4mm DAT drives will upchuck when fed SCSI in synchronous mode, even after happily negotiating sync mode with the SCSI card. If you have a reasonably advanced SCSI card, set the SCSI ID on the tapedrive to max 5MBt and no sync negotiation. The only thing you really need to have running on a SCSI tape drive is disconnection.
