hi guys,

i have installed gentoo kernel 2.6.5 and i have a cdwriter as hdd and an asus dvd rom as hdc, the problem is that when I try mount /dev/cdroms/cdrom /mnt/dvd I receive /dev/cdroms/cdrom0: Input/output error
mount: block device /dev/cdroms/cdrom0 is write-protected, mounting read-only and dmesg gives me :ide-cd: cmd 0x28 timed out
hdc: DMA timeout retry
hdc: timeout waiting for DMA
hdc: status timeout: status=0xd0 { Busy }
hdc: status timeout: error=0x00
hdc: drive not ready for command
hdc: ATAPI reset timed-out, status=0x80
hdd: DMA disabled
ide1: reset timed-out, status=0x80
hdc: status timeout: status=0x80 { Busy }
hdc: status timeout: error=0x01IllegalLengthIndication
hdc: drive not ready for command
hdc: ATAPI reset timed-out, status=0x80
ide1: reset timed-out, status=0x80
end_request: I/O error, dev hdc, sector 0
Buffer I/O error on device hdc, logical block 0
end_request: I/O error, dev hdc, sector 8
Buffer I/O error on device hdc, logical block 1
end_request: I/O error, dev hdc, sector 16
Buffer I/O error on device hdc, logical block 2.....
............

also i can't boot the live cd on my dvdplayer only the cdwriter works fine, any clues?

tks

Have you tried naming them "/dev/hdc & /dev/hdd"? I have a Lite-On CDRW and a Lite-On DVDRW and had to use this method of naming them to get them to mount correctly.

what do you mean by that?

thanks

Sorry, been away from the computer too long.

Anyway, what I meant is mount them by "mount /dev/hdc /mnt/dvd" and "mount /dev/hdd /mnt/cdrw" and then change your fstab file accordingly.

Judging by all the DMA errors I might venture to guess your drive might not support DMA for some reason. Try using hdparm * think thats it * to turn off DMA for that drive.
