Has anyone had a problem where a scsi bus reset rewound the drive without

I have no evidence that "scsi bus resets" or anything else in particular
was the cause, but I have seen tape corruption of older versions of
networker that appeared to be caused by unexpected rewinds.


Some SAN hardware using certain older firmware versions suffered from a
problem where the type of SCSI resets sent was particularly destructive
in this sense. The solution was to upgrade to firmware versions that did
not send TPRLO resets.
