Problems with drives...
 

My linux distribution is Ubuntu 6.10.
I have 2 Seagate HDs (one is a ST320413A - with a NTFS partition - the other is a ST320413A - on which I have installed Ubuntu 6.10 - according to /proc/ide/hd?/model) and a "BENQ DVD DD DW1640" (one again, pasted from /proc/ide/hdd/model). I have serious problems accessing the drives. If I have the two HDs on the same channel (yep, Parallel ATA :( ) the system hangs, although if I tell the kernel not to probe /dev/hda, everything works fine (but I can't access one of my Hard Disks...). I tried moving my second HD to Secondary Primary, and I can access the two HDs at the same time... but! I have moved the DVD burner to Primary Slave, and what happens? I can't use it... the DVD burner seems to "crash", it doesn't even eject the CD... the same happens if I move the DVD burner to the Secondary Slave channel...

Is there any way to avoid this?

(I would like to post my dmesg, but it's way too long :rolleyes: )

Never had that much trouble with harddrives and optical drive combinations. If none seem to co-exist a the same channel then you can get a PCI IDE controller and run the thrid device off it.

Make sure the jumpers on the drives are configured correctly.

I have fixed the problem by setting the DVD drive to work at UDMA 1, not 2...

(hdparm -d 1 -X udma1 /dev/hd?).
