My laptop hard drive crashed due to a corrupted MFT. I have installed its HDD as a slave in my workshop C666 and booted DOS4NTFS from a floppy. I consistently get a UMB error. The specific message is "Exception: 0E Error Code: 004". Does anybody have any idea as to what might be causing this and how to fix it?

That's a good one. They give the error code but don't tell you what it means. Par for the course. If you've got nothing of importance on the drive refarmat and install an operating system. Start over. If you have important files then see if you can copy them to another drive then reformat and start over. If your computer crashed how do you know that it was a MFT corruption? Were you fooling with the MFT before the crash?

Unfortunately, the drive has important data on it. The sad tale is that the DC input connector's central (ground) pin broke off and probably cased a brief series of sparks as it worked itself loose. The reult is one of my memory banks is fried and the HDD MFT is corrupt. The HDD was scanned by CHKDSK with the command console after being installed as slave in an old desktop system I keep in my workshop. While the MS CHKDSK program can only find problems, DOS4NTFS can fix them. I have been able to repair MFTs in the past and get XP and WIN2K drives useable again. Mechanically, the drive is sound.

Interesting about using DOS4NTFS to repair and fix the drive. Where can I find more information on using DOS4NTFS? Must one be experienced to use it? Where can I get a copy?
