DVD/CDRW Drive Disappeared After Reboot

[Dieter Schmitz]

Hi,
I've swapped my CDRW for a DVD/CDRW Combo (Samsung SN-324B firmware
U002). I managed to have the drive being recognized by switching off
DMA support from the IDE controller properties. Then I switch back
from PIO to DMA and all works fine. When I start the system the next
time the drive is gone and I got to repeat the DMA ceremony. I already
thought of writing a little script that does this trick on startup.
But there should be a proper solution out there, something like a
registry switch to make my drive "permanent".

Any ideas?

Best regards,
Dieter

Hi

In BIOS, can it recongnize the DVD/CDRW Combo correctly
If yes, is the DVD combo set as secondary slave
If yes, are you using a 40 Pin IDE cable instead of a 40 Pin 80 conductor shielded IDE cable

I would suggest you to update the mobo BIOS and chipset drivers and use a 40 Pin 80 conductor shielded IDE cable

I forgot to mention: it's a notebook PC. The BIOS setup screen isn't
that detailed as with a desktop PC. But the drive is recognized and it
boots both in BIOS mode as with the OAK driver under DOS. It also
boots Windows XP setup PE and I have had a clean PnP installation
under XP using PIO mode and then I switched to DMA.

Or doesn't switching from PIO to DMA (without reboot) have no effect
at all? Then I could stay with PIO and be happy.
