Any plans to fix 'hdparm -I /dev/atapi-cdrom-device' I reported to
you and Bartolomiej at the end of June? ide_*_taskfile
sets REQ_SPECIAL, but ide-cd calls cdrom_end_request(drive, rq, 1)
on all such requests without looking at them or without trying to
execute them. This forces hdparm -I to think that ATA identify
suceeded and returned all zeroes:
/dev/hdd:
removable ATA device, with non-removable media
Standards:
Likely used: 1
Configuration:
Logical max current
cylinders 0 0
heads 0 0
...
Capabilities:
no IORDY
Cannot perform double-word IO
r/w/ multiple sector transfer: not supported
DMA: not supported
PIO: pio0
while 'hdparm -i' correctly reports that it is Toshiba DVD device
supporting IORDY, pio0-4, sdma0-2, mdma0-2, udma0-2, according
to ATA2-ATA5.
Thanks,
