Q. Why do I receive a KERNEL_DATA_INPAGE_ERROR code when I start my computer?

A. The KERNEL_DATA_INPAGE_ERROR code indicates that the paging-file access process failed to find a page of kernel data. This problem has several possible causes. To determine the cause, look at the line that's under the main error message, which provides diagnostic information. The second parameter in this line is the I/O status code, which gives detailed information about the actual cause of the problem. The Table lists common KERNEL_DATA_INPAGE_ERROR error codes and their meanings. For example, on my computer I received the 0xC000009C error code--STATUS_DEVICE_DATA_ERROR--which indicates bad blocks (sectors) on the hard disk. To resolve the error, I booted to the Recovery Console (RC) and ran the command

chkdsk c: /r

The Chkdsk command found the bad blocks and fixed them; the machine then rebooted correctly.
