I get the followng message when trying to run Chkdsk via a Command Prompt: "The type of file system is NTSF. Cannot lock current drive. Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts ? (Y/N) " When I answer yes to do a check at restart, I do get a the Chkdsk screen but it immediately says the Chkdsk was cancelled before I input anything or hit a key to actually cancel the test. I have no idea what other process is running. Any ideas?
