CDROM Errors

The device, \Device\CdRom0, has a bad block.
An error was detected on device \Device\CdRom0 during a paging operation.
The device, \Device\Ide\IdePort0, did not respond within the timeout period.

These are the errors i found in event viewer. Running WinXP pro, DVD Writer:Samsung TS-H552U on primary master n Samsung cdrom on primary slave. HDD on SATA1. Got these msgs (recent ones) wehn viewing magazine dvd.

used to get these even for cd-rom too. wat do they mean?

also, if any music is playing and at the sametime cd or dvd is accessed, the sound becomes choppy. Wat could be the cause?

points given for both queries.

you can have to clean the lens of your cd drive
and check if your drive operates in DMA, not PIO :
in device manager, right click on the ide atapi controllers, select properties, advanced tag
if it is in PIO, here how to reset it   :  
Load RegEdit (Start - Run - Regedit)

Go to the following keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\000x

The last four digits will be 0000, 0001, 0002, 0003,
Under each key, delete all occurences of the following values:

     MasterIdDataChecksum
     SlaveIdDataChecksum
If you do not have an entry for ResetErrorCountersOnSuccess :   at each of the keys (0001, 0002, 0003, etc.) you should add a DWORD value named "ResetErrorCountersOnSuccess" with a value of 1

The errors are typical when the CD can't be read properly. Maybe it is scratched or too dusty? If cleaning the lens doesn't help there isn't much you can do.

The choppyness is caused if you are running both drives at the same time from the same IDE channel. An IDE controller can only access one connected device at the same time on the same channel. Since you probably aren't using both channels (your HD is SATA), and you probably do have 2 IDE channels, connect one of your optical drives to the other channel.

nobus: the 0000 doesnt have any of the values u asked me to delete. is it normal. the primary IDE in the device manager, shows device 0 in PIO mode and device 1 on Ultra DMA 2 mode. whereas the other primary IDE shows "not applicable" under current transfer mode. is it of any significance?

If you have both optical drives running at the same time and they are connected to the same IDE channel like in your situation, they'll start and stop one after the other. Just try connecting one of those drive to the other IDE channel. Of course running in PIO mode also won't help...
