I know this is ancient technology, but we have a pile of exabyte tapes made on an 8200 and would like to recover some of the data on them. We have an old 5.3 machine which has an adaptec 2120S, and the Exabyte is connected to that. The kernel identifies the Exabyte on boot, but it's all downhill after that. The driver sometimes spits out a pile of errors (I'll append a sample at the end) and mt doesn't seem to do simple commands (like a retension). I note that the MT page for 5.3 says that not all SCSI-1 devices are supported. So before I invest more time in this, I am wondering if anyone can tell if the support is there for this configuration? If not, what (inexpensive) options do I have for possibly retrieving this data? Thanks a lot, Scott -- sdb@ssr.com An "mt status" causes the driver to report: (sa0:aacp0:0:4:0): MODE SENSE(06).
