Hi. Sorry if I create topic in a wrong place. I'm new here.

My problem is that I have MFT <200mb (am i right that it kinda creates second 'block' only after exceeding 200mb?) in 2fragments and no defrag software can take care of that. All of 'em, including MyDefrag, just procede with defragmentation but leave MFT as it is informing of no errors or something. Any help?

The two fragmens of hte MFT are they nearly aqually of size or is the first fragment very small?

If it is very small, Windows can not move the complete MFT, the header is fixed, only the MFT data is movable.

Well, one fragment is about 1/6 size of another. But which is 'first'?

P.S. Some software states, that the read speed from those 2 fragments is 2x the normal read speed of my HDD, so that's why I thought this issue ever worth mentioning.

Managed to find a piece of software that did this job. Sorry for the trouble, and thanks. I like MyDefrag optimizations very much but maybe developers could improve MFT handling... would be great so that no problems occur anymore.

Apart from the MFT-header BloodySword mentioned, the main part tries to stay in one piece until there is a file at it's end, blocking it's growth. So it has to fragment itself to grow further. Some defragmenters (including MyDefrag) can defragment the MFT since Windows XP. The problem you can run into when using an optimization script instead of the Defragmentation script is that MyDefrag can wrap the MFT around an unmovable file, hence fragmenting it.

P.S. Some software states, that the read speed from those 2 fragments is 2x the normal read speed of my HDD, so that's why I thought this issue ever worth mentioning.
Which software does that? It is likely that MFT has been cached and the software is reading it from there, bypassing the slow HDD.
