I am getting the above error. I noticed it after I scheduled a routine maintenance disk Error Checking on my Windows 7 64-bit laptop and realized it was not running it on reboot.
I rebooted to the Windows 7 installation repair disk and from the Command prompt got this error: "Cannot Lock Current drive... Windows cannot run disk checking on this volume because it is write protected".
I have tried everything ... the drive was not giving any problems. I downloaded and installed the Seatools for Windows ... it runs the scans and does not report any problems on the drive.
Has anyone experienced this error on Windows 7?
