I adjusted the function that detects tape block size so that it is capped to MAXPHYS. I also fixed the debug message so that I get the scsireq_t NetBSD field names correctly displayed and filled: LTFS20039D Backend read: 65536 bytes LTFS20010D SCSI request: [ 08 02 01 00 00 00 ] Requested length=65536 LTFS20089D Driver detail: errno = 0x0 LTFS20089D Driver detail: status = 0x2 LTFS20089D Driver detail: retsts = 0x4 LTFS20089D Driver detail: error = 0x0 LTFS20011D SCSI outcome: Driver status=0xFF SCSI status=0xFF Actual length=0 LTFS20042E EIO in read : I now get SCCMD_UNKNOWN / Check Condition.
