When the error does come up, there's usually a parameter code that goes with it in the form of a number: OxC000009A, or something similar. The code is usually a key to what is wrong:
- 0xC000009A, or STATUS_INSUFFICIENT_RESOURCES, is caused by lack of nonpaged pool resources (low physical memory).
- 0xC000009C, or STATUS_DEVICE_DATA_ERROR, is typically due to bad blocks(sectors,) on the hard disk.
- 0xC000009D, or STATUS_DEVICE_NOT_CONNECTED, indicates defective or loose
cabling, termination, or the controller not seeing the hard disk.
- 0xC000016A, or STATUS_DISK_OPERATION_FAILED, is also caused by bad blocks (sectors,) on the hard disk.
- 0xC0000185, or STATUS_IO_DEVICE_ERROR, is caused by improper termination or defective cabling on SCSI devices, or two devices attempting to use the same IRQ.
Most often this sort of error is caused by either a bad hard drive or a defective bit of cabling. It is also caused by failing hardware of other kinds -- usually a bad RAM module, something which in itself is probably responsible for about a good half of the random crashes/lockups that happen on a computer.
