Something similar happens to me, too. I've got the following hanging off an Adaptec 1542c: (aha0:3:0): "ARCHIVE Python 25947-XXX 2.49" type 1 removable SCSI 2 The drive is DDS only; no DDS-2. I get timeout messages, and a bit later, the kernel panics. If I reset the drive and 'c'ontinue from the console debugger, I can sometimes recover. I also have another Archive Python (both are Compaq OEM) with a slightly higher model number which does read Sun tapes. They are both old; at least 2 years, and have been used daily. I think the Archive hangs when it reads a compressed tape that it can't handle, since I can create tapes on the new drive that hang the old one. I'm not sure if my problem is the same as yours; just adding another datapoint. -Dan Nelson dnelson@emsphone.com
