Problem while copying content from CDROM
 

Hello All,

I have bought a new computer. Here comes the PC config

P4 2.6 Ghz
Mercury 915 Chipset mother board
512 MB RAM
Samsung 52x CD ROM
Samsung 16x DVD +- DL Writer
80 GB HDD
etc..

Problem is When ever i copy any content from CD ROM drive my PC becomes very slow. I beleive this is a Slave drive.

The same does not happen if i copy from DVD Writer. I belive this is a Master

Also i changed my CD ROM as Master and tried, again this problem occurs. I tried replacing the CD ROM drive. but still the problem persists..

Any idea why this is happening?

Thanks in advance

Regards

try a new IDE cable

also check out some of your registry settings. I had a similar problem when I got a new CD-R drive...


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."

From FOX
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.

Thankx mikeh420. I will try the registry settings..also i wil update this thread after my testing..thanks once again!

If your hard drive and your cd rom are on the same IDE channel, then that is likely the problem.. Check the internal configuration.

Yes, back in the day when there was only one IDE channel on a M/B, the CD-ROM drive slowed down the HDD because the CD-ROM has slower transfer rate

MY HDD is connected via SATA..only 2 ide's in my PC..one for my CD ROm and one for DVd Writer
