PATA DVDRW Problem (possibly NOT connected with libata)

[oleg.strikov]

I have pretty interesting situation with my PC (A64 3000, ASUS A8N-E).
I can see /dev/sr0 device without any problems, but there are a lot of faulty operations connected with it (I/O Errors)

Standart disk read error message (dmesg)

sr 5:0:0:0: [sr0] Result: hostbyte=0x00 driverbyte=0x08
sr 5:0:0:0: [sr0] Sense Key : 0x4 [current]
sr 5:0:0:0: [sr0] ASC=0x8 ASCQ=0x3
end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

One or two year ago i've solved such problem on my FreeBSD machine using something like:

set ata.atapi_dma=0

I've already done smth like

libata.atapi=0

but without any results sad

P.S. It's not a DVDRW hw problem, cause i've checked Pioneer & Samsung devices

Thanks!

Hi and Welcome !

Check /etc/fstab file. Is udf filesystem specified for /dev/sr0? Try removing that.

My /etc/fstab contains

/dev/sr0         /mnt/dvd         iso9660     noauto,user,ro   0   0
