Cd/dvd Drive Not Burning At Proper Speed!
 

So, lately, my cd/dvd drives are not burning at their posted speeds;
I am supposed to get 48x on the cd drive, and it wont go above 32x

The dvdr is supposed to get 16x, but wont go above 4x

I am using media that is supposed to burn at those speeds, but they dont.

I know we have talked about this before, and what to do to fix it, but I cant find those posts..

thanks so much!

Glad I saved this one...

If in Primary or Secondary IDE Channel Properties in Device Manager, under the Advanced Settings tab, it shows Current Transfer Mode as PIO, and cannot be chaged back to Ultra DMA Mode 4, even by rebooting, then you need to edit the registry...

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type ResetErrorCountersOnSuccess, and then press ENTER.
5. On the Edit menu, click Modify.
6. Type 1, and then click OK.
Follow these steps, and then quit Registry Editor:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type ResetErrorCountersOnSuccess, and then press ENTER.
5. On the Edit menu, click Modify.
6. Type 1, and then click OK.
Note The numbered subkeys that are listed earlier correspond to the primary and secondary IDE channels on a computer that contains a single IDE controller. If your computer contains two IDE controllers, the numbered subkeys for the primary and secondary IDE channels for each of the two controllers may be:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0003
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0004
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0005
To verify that you have located the correct subkey, verify that the DriverDesc value for the subkey contains the string value "Primary IDE Channel" or the string value "Secondary IDE Channel."

reg. key :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001 or 0002 (depending on beeing primary[0001] or secondary[0002] ide channel)
there you modify the DWORD value of :
if the drive is on master: "MasterDeviceTimingModeAllowed" or
if the drive is on slave: "SlaveDeviceTimingModeAllowed"
to ffffffff
then go back to your device manager set your drive in IDE channel properties first back to pio and then, after confirming, again to dma ...that should do the trick

From McoreD
CD-ROM and DVD-ROM drives can revert to using PIO mode, despite being set to use "DMA if Available." Here's how to make Windows XP redetect the DMA capabilities of the drives.
This behaviour occurs with the following conditions:
Windows XP is the operating system
A CD-ROM or DVD-ROM drive, which is known to support DMA mode now works only in PIO mode.
The drive controller is set to use "DMA if available" but reports to be only in PIO mode.
Following is the mechanism that has worked for me, please try it at your own risk, it involves hacking the registry:
Open RegEdit
Find the following KEY:
CODE
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\ Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\000x
The last four digits will be 0000, 0001, 0002, 0003, and so on.
Under each key, delete all occurences of the following values:
CODE
MasterIdDataChecksum
SlaveIdDataChecksum
Reboot the computer. Windows will now redetect DMA settings.

thanks...good info here man!

i think ill keep a copy of this !!

Thx alot!
