Master File Table (MFT) corruption

By rcube ·
Does anyone here knows the solution when an MFT corruption occurs on an NTFS volume of a Win NT 4.0 Server running MSCS?

We had encountered this problem when our stored data reached 415GB. We are using a two Compaq 8500 and an RA8000.

Sounds pretty lame! I know that you most likely might have done these things...but, just in case. WARNING: please be advised that a backup is MANDATORY when doing thins..and at 415GB..that's a pain!
You can start by running CHKDSK /F This is what is run when NT is shut down dirty. The dirty parity bit is set for this to happen automatically. The other is to run SCANDISK.. Right click on DRIVE, properties...tools...and boom...check the thing.

BUT, to answer your question why??
This problem occurs when the Master File Table (MFT) has grown larger than 4 GB, which may happen when you have more than 4 million files on your computer. When you delete a file whose MFT entry is beyond the 4 GB point under these conditions, an error in calculations causes the wrong entry to be marked as available. If this entry contains information for another file, and new files are added to the volume shortly after the deletion occurs, the entry could be re-used causing the file it actually referenced to be lost.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update.
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was first corrected in Windows NT Server version 4.0, Terminal Server Edition Service Pack 6.
Information on all files in an NTFS volume is stored in the MFT. The MFT contains one or more an entries for all files on the system. In addition, the MFT maintains empty or unused entries which can be used for newly created files. When a file is deleted, it's entry is marked as being unused so that when a new file is created, the file system can re-use the entry.

Hope this helps you some... Latez-

Oh...btw, this doesn't appear to be an issue with the Microsoft Cluster Server. It is related to the drive and directory/file handling.
