Reactivating Dead DVD/CDRW Drive By Switching DMA-PIO-DMA Mode

[Dieter Schmitz]

Hi,
I've swapped my CDRW for a DVD/CDRW Combo (Samsung SN-324B firmware
U003). 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 have to repeat the DMA-PIO-DMA procedure.
Is there a way to automate this stupid ceremony?

Any more registry hacks? I've tried all I could find on the web. I've
de-installed the CD-Driver, deleted the secondary IDE controller and
rebooted. The drive was detected and properly installed:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002]
"EnumPropPages32"="storprop.dll,IdePropPageProvider"
"InfPath"="mshdc.inf"
"InfSection"="atapi_Inst_secondary"
"ProviderName"="Microsoft"
"DriverDateData"=hex:00,80,62,c5,c0,01,c1,01
"DriverDate"="7-1-2001"
"DriverVersion"="5.1.2600.1106"
"MatchingDeviceId"="secondary_ide_channel"
"DriverDesc"="Sekundärer IDE-Kanal"
"MasterDeviceType"=dword:00000002
"SlaveDeviceType"=dword:00000000
"SlaveDeviceDetectionTimeout"=dword:00000001
"MasterDeviceTimingMode"=dword:00000410
"MasterDeviceTimingModeAllowed"=dword:ffffffff
"MasterIdDataCheckSum"=dword:0000f273
"SlaveDeviceTimingMode"=dword:00000000

After reboot the drive is gone again:
....
"MasterDeviceType"=dword:00000000
"SlaveDeviceType"=dword:00000000
"SlaveDeviceDetectionTimeout"=dword:00000001
"MasterDeviceTimingMode"=dword:00000000
"MasterDeviceTimingModeAllowed"=dword:ffffffff
"MasterIdDataCheckSum"=dword:0000f273
"SlaveDeviceTimingMode"=dword:00000000
"UserMasterDeviceTimingModeAllowed"=dword:ffffffff


After I switch to PIO mode (the drive now activated):
....
"MasterDeviceType"=dword:00000002
"SlaveDeviceType"=dword:00000000
"SlaveDeviceDetectionTimeout"=dword:00000001
"MasterDeviceTimingMode"=dword:00000010
"MasterDeviceTimingModeAllowed"=dword:ffffffff
"MasterIdDataCheckSum"=dword:0000f273
"SlaveDeviceTimingMode"=dword:00000000
"UserMasterDeviceTimingModeAllowed"=dword:0000001f


and then back to DMA:
....
"MasterDeviceType"=dword:00000002
"SlaveDeviceType"=dword:00000000
"SlaveDeviceDetectionTimeout"=dword:00000001
"MasterDeviceTimingMode"=dword:00000410
"MasterDeviceTimingModeAllowed"=dword:ffffffff
"MasterIdDataCheckSum"=dword:0000f273
"SlaveDeviceTimingMode"=dword:00000000
"UserMasterDeviceTimingModeAllowed"=dword:ffffffff

BTW it's "Multiword DMA Mode 2".


What more can I try? I might as well consider swapping the drive at
eBay...

Best regards,
Dieter

Chabge the IDE cable. To use DMA, you need a good 80pin IDE cable.

....thank you, Yves. I would try this but the Samsung SN-324B is an
internal notebook drive - no cable to change.

Hi

Try update the BIOS and chipset drivers from the laptop manufacturer's website
You should also search the support website for issues on DVD Combo drive

Hi,

....Inspiron 3200 of 1998 - no more updates available.

I decided to stay with the drive and give it a kick-start after
reboot. I don't have to reboot so frequently since I installed XP.

I decided to stay with the drive and give it a manual "kick-start"
every time I reboot. Fortunately I don't have to reboot so frequently
since I installed XP
