To chkdsk or Not Bother After Kernel Error

HI,
I was running a rather large statistics (SAS) model on XPsp2, after 2 hours got:

KERNEL_DATA_INPAGE_ERROR on XP;
the disk was making a bit of noise, but not much.

The kernel code basically says the system halted after it was unable to find or use a storage resource. Given the strange disk noise, I'm worried.

Ran chkdsk at a low boot level and the problem has not come back. The other thing is that this system seems really slow recently. Defraged the disk using diskkeepper. So I've done all the common user-level stuff.

Any suggestions? Thanks and Cheers!!

Hi,
what was the outcome from check disk, did it find and repair any errors?
what for a disk drive are you using?
what was the exact error code?
check your event log for the exact error code

0xC000009A
STATUS_INSUFFICIENT_RESOURCES
Indicates a lack of nonpaged pool resources

xC000009C
STATUS_DEVICE_DATA_ERROR
Indicates bad blocks (sectors) on the hard disk

0xC000009D
STATUS_DEVICE_NOT_CONNECTED
Indicates defective or loose computer or power cables, a problem with SCSI termination, or improper controller or disk configuration

0xC000016A
STATUS_DISK_OPERATION_FAILED
Indicates bad blocks (sectors) on the hard disk

0xC0000185
STATUS_IO_DEVICE_ERROR
Indicates improper termination, defective storage controller hardware, defective disk cabling, or two devices attempting to use the same resources

Then provide us with that information.
