When attempting to write to the drive, it returned an unknown error code. This typically occurs when using a newer drive or controller with an older OS or driver that is not up-do-date with the latest publicly defined error codes.
The device reported an error on a request to write data to media. Error reported: Unknown error. There may be a hardware or media problem. Please check the system event log for relevant failures.
After attempting to save any open files, perhaps to a different drive than the one reporting problem, power down the system. With a bit of luck this is a one-time occurrence, although running a disk check (see below) is recommended.

Fix Data Corruption
Data and/or file structures on the drive may be corrupt. Run the check disk program or other disk validation and repair utility on the drive. To do this:
Open Explorer or My Computer (Press Windows+E).
In the right pane, right-click on the drive you want to validate and select Properties.
Select the Tools tab.
Under Error-checking, click on "Check Now".
In the next dialog, make sure the option "Automatically fix file system errors" is checked. If you want a more complete validation and repair check the option "Scan for and attempt recovery of bad sectors" (although this takes considerably longer to complete).
If you had changed, added or removed hard drives, or changed or removed drive cabling, likely something is wrong. Recheck that the drives are properly installed and the cabling has not changed. Switching cables to different motherboard connectors or changing the master/slave drive jumpers (on old ATA drives) can cause this problem. In some systems, the cables were not plugged into the drive or motherboard securely and may have worked loose. Reseat all drive connectors.
It's also possible a hard drive is failing. Use a system diagnostic to validate the drive or swap to another hard disk.
