A problem occurred within NTFS.SYS, the driver file that allows the system to read and write to NTFS file system drives. There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive-mirroring software, or some antivirus software.
I suggest running chkdsk /r from the Recovery Console. You can download an .iso file of the RC, then burn it to CD, creating a bootable CD which contains the RC.
Once that is done, run the chkdsk /r command from within the RC.
