News to me. ATA like ST-506/ST-412 exposes error data on I/O READ/WRITE
via the READ_BUFFER functionality but its basically useless without a lot
of knowledge of the drive on anything post ST-412 era.

Got any references ?

The other possibility is to whine but accept it happens - on the other
hand being lax about HSM errors is asking for corruption and it seems
to be unique to this tape device.

(and someone please don't tell me early pre ATAPI standard devices are
trying to return the sense data in this way or I'll be ill)
