It immediately switches to the status phase 0xb8 after receiving the subpage code 0x05 of MODE_SENSE_10 command, which fails imm_out() and turns into DID_ERROR of this command, which leads to unusable device. This was tested with an Iomega ZIP 100 (Z100P2) connected with a StarTech PEX1P2 AX99100 PCIe parallel port card. Prior to this fix, Test Unit Ready fails and the drive can't be used: IMM: returned SCSI status b8 sd 7:0:6:0: [sdh] Test Unit Ready failed: Result: hostbyte=0x01 driverbyte=DRIVER_OK Signed-off-by: Florian Fuchs --- drivers/scsi/scsi_devinfo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/scsi_devinfo.c b/drivers/scsi/scsi_devinfo.c index 0dada89d8d99..68a992494b12 100644 --- a/drivers/scsi/scsi_devinfo.c +++ b/drivers/scsi/scsi_devinfo.c @@ -190,7 +190,7 @@ static struct { {"IBM", "2076", NULL, BLIST_NO_VPD_SIZE}, {"IBM", "2105", NULL, BLIST_RETRY_HWERROR}, {"iomega", "jaz 1GB", "J.86", BLIST_NOTQ | BLIST_NOLUN}, - {"IOMEGA", "ZIP", NULL, BLIST_NOTQ | BLIST_NOLUN}, + {"IOMEGA", "ZIP", NULL, BLIST_NOTQ | BLIST_NOLUN | BLIST_SKIP_IO_HINTS}, {"IOMEGA", "Io20S *F", NULL, BLIST_KEY}, {"INSITE", "Floptical F*8I", NULL, BLIST_KEY}, {"INSITE", "I325VM", NULL, BLIST_KEY}, base-commit: 2f38fd99c0004676d835ae96ac4f3b54edc02c82 -- 2.43.0
