ide dvd burner detected as ide-tape

[Thomas Drillich]

Hi,

I found in the syslog:
Sep 30 13:44:44 localhost kernel: ide-tape: hda <-> ht0: HH-@T)SPȴ/�����1*00

-- end snip

but its a LG GH22LP20 DVD burner

cat /sys/bus/ide/devices/0.0/model returns
	HL)DP-ST@V@-RAI CH22HP20

what can I do ?

What udev rule? It's the kernel which need to know that this device
isn't a tape but an optical drive. :)

ide-tape driving DVD burner is a "CANNOT happen" case...

Thomas, which kernel version is it?  Please post a full dmesg output.

Thanks,

Seems that can happen Bart ;-)

it's a 2.6.26.5 kernel running on debian/testing.

I moved ide now to module
 alim15x3                7504  0 [permanent]
 ide_pci_generic         5252  0 [permanent]
 ide_core              140572  2 ide_pci_generic,alim15x3

but it didn't changed anything .. as expected.

>lspci
 00:1f.0 IDE interface: ALi Corporation M5229 IDE (rev c7)

I added /proc/config.gz to the dmesg output

so this is a probing time device type misdectection
(yeah, the impossible has just happened ;).

Does BIOS also detect this device as "HL)DP-ST@V@-RAI"?

Please send the output of "hdparm --Istdout /dev/hda" so we can check
whether the problem is a bogus (corrupted?) identify data or some issue
with the device type detection code...

Could you also try 2.6.27-rc9?

I'm not able to run hdparam on /dev/hda, udev won't create the device file and
if I create the device file manually hdparam just stop working.

I'd attached cat /proc/ide/hda/identify (hda.identify.txt.gz).

no changes in that kernel version .. I attachted output of dmesg of that 
kernel version.

Thanks.  Does the following patch help?

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ide: quirk for LG GH22LP20 DVD burner

LG GH22LP20 DVD burner ("HL)DP-ST@V@-RAI CH22HP20") with firmware 1.00
reports 0x01 ("Sequential-access device") as the peripheral device type
instead of 0x05 ("CD-ROM device").

That looks more like a hardware problem with a flakey bit.
For example GH22LP20 with bit 2 always cleared = CH22HP20.
DVD-ROM with bit 2 sometimes cleared = @V@-RAI.
And the peripheral device type also has bit 2 cleared.

This would explain it nicely (I suspected something along these lines
but failed to see the actual pattern).  After all it is very unlikely
to have _that_ broken firmware.
