BE 4.2 (upgrade from Seagate), Seagate STT8000A drive (internal).

Consistently receiving "The device received an invalid command Ref:
05-20-23-00-0403"

Tried new media, same problem. Problem appeared suddenly and was
immediately repeatable.

Anyone have a clue? I sure don't! Only thing I can think of is bad drive,
which is about one year old but used nightly for differential backups and at
least monthly for full backups.

Remove the NO and SPAM from the address if replying directly.

Thanks,

Mike
