What is drive X using MS-Dos compatibility mode file system?


i get the following error when i click on my computer and click on performance i get

"Drive X is using an MS-DOS compatibility mode file system.

This problem often occurs on more than one drive. Usually it is caused by a driver listed in the Config.sys file that Windows does not recognize and that is related to the message Compatibility mode paging reduces overall system performance. If you see both messages, see the Help for the Compatibility mode paging reduces overall system performance message first.

If you only see the message Drive X is using an MS-DOS compatibility mode file system on one drive, that drive is using an MS-DOS compatibility (real-mode) driver, which may reduce that drive’s performance. Contact your hardware manufacturer to see if an updated driver is available for your drive. If not, the drive’s performance may be less than optimal, but you can still use it."

i get this with drive C and drive D(both my hard drives) and my cd rom drive is not detected in my computer or in device manager. what should i do?...
