Can someone tell me what's happening here?  Is it hardware or maybe just
a bad tape?  The situation:  All attempts to read/write/erase or even
get status of any tape results in the error message below. The drive was
working prior to my upgrade to 4.3-R, and now to 4.5-Pre.  Have tried
the card (2940 adaptec) in a windows machine with no luck either.  Also
have tried identical drive, new cable, same configuration, etc..
terminators are in place. At this time, I'm doing an erase, but the
green led on the drive is not lit up. The amber led is, but not
flashing.

Any ideas/help appreciated.

Sam
