The MFT is the heart of an NTFS partition. There is at least one entry in the MFT for every file on an NTFS volume. All the information about a file, including its' size, time and date stamps, permissions, data content, etc. are stored in the MFT (or in space described by the MFT).

To prevent fragmentation of the MFT, NTFS reserves space for the MFT in an effort to keep it as contiguous as it grows. This is important because defraggers can not move MFT records and fragmentation of the MFT can severely impact performance. (Current defraggers do this at boot time)

When you add files to an NTFS volume, entries are added to the MFT. When files are deleted from an NTFS volume, their MFT entries are marked as free and may be reused, but the MFT does not shrink. Thus, space used by these entries is not reclaimed from the disk.

NTFS reserves a percentage of the volume for exclusive use of the MFT. Space for files and directories will not be allocated from this MFT zone until all other space is allocated first. Depending on the average file size and other variables, either the reserved MFT zone or the unreserved space on the disk may be filled first. Volumes with a few large files will exhaust the unreserved space first, while volumes with a large number of small files will exhaust the MFT zone space first. When either the MFT zone or the unreserved space fills, fragmentation of the MFT starts. If the unreserved space becomes full, space for user files and directories will be allocated from the MFT zone. If the MFT zone becomes full, space for new MFT entries will be allocated from the remainder of the disk.
The ball bounced over my head.:-).
Can the problem be solved ? . maybe low level formatting?

It has no jumpers on it.

499291 2006-11-30 11:21:00 Try a linux live disk like Knoppix.It does seem very strange tho.
What is that going to prove they said they have already tried QTParted and it recognised everything. QTParted is a Linux program very similar to PartitionMagic.

Can be very risky with some drives . My guess would be a Bios problem but why things should have changed is another story .
