Windows 7: Windows defragger overwrites mft zone

14 Nov 2009   #1

win 7.600
Windows defragger overwrites mft zone


there's a problem i found....
after i installed all programs i needed...and made sure i cleaned with Ccleaner...i used ultimate defrag as a visual guide(just because it doesnt work well in win 7) and saw plenty of space in reserved MFT....i assured this is setup in registry to value 1 ...meaning 12.5%....and started defragging with its original disk defragger....
...after it was done....i used ultimate defrag as a visual guide again....there was all nice and smooth....but MY RESERVED MFT WAS GONE
u can see in ultimate defrag every file positioned to the cluster no....
before defragging i assured after MFT it was MFT reserved(in ultimate defrag)...and after...there were some other files....and MFT reserved was gone....
after a restart....the MFT reserved was recreated in an inner cluster on disk....meaning...when this will be 100% fragemnted MFT in near future

in regedit MftZoneReserved its still on value 1

u can do a test....

make sure the reserved MFT is there....then defrag with original defragger then take a look again...

maybe only i have this problem

the only way to get the reserved MFT rite near the MFT is by using perfect disk boot time defrag...i tried this many times....
every time its the same....disk defrag overwrites mft reserved space....and i gotta put it back with perfect disk...

i didnt find the problem on the web so maybe u can help....thx

You didn't find this on the web, because it is a none issue. The defragmention engine is Windows 7 is more then smart enough to know exactly what it is doing.

win 7.600 come fragmented MFT is not an issue ???

once my mft is doesnt become into one piece again...i read there about the improvement of moving metadata...but MFT is still fragmented....

i tried this too....i figured that if defragger overwrites the MFT might be able to defragment it aswell...but its not my case....once fragmented...never defragged...

and why should microsoft bother to alocate value 1 to MftZoneReservation if defragger overwrites it anyway ?...why not disable it and drfragment it when it grows ??...

i dont fully understaind ...or maybe i missed something ?....thx

i did some tests.....boot defragger clears the mft zone.....and mft becomes fragmented as soon as it needs to expand.....

boot defragger is an iddle process task....but can be started with "defrag c: -b"

tried on more machines....this task overwrites the mftzone....same story

why does it do that ?

windows defrag cannot defragment the MFT after that....

i need to disable disk defragger from services....and use something else....

looks like perfect disk 10 does the job well....

PS: this problem doesnt bother anybody ?...

There are also "memory optimizers" too. Just because something exists, doesn't mean it does anything useful.

Though, sadly, if your going to compete inthe marketplace and the other 5 defrag utilities that defrag the MFT then by ghod you better too!

win 7.600

well since vista....the point was ....that u will need less aditional software instead of maybe more....

the thing is....after a windows defrag the boot time decrease with few sec(3-5) than with any other defragger....

but MFT gets fragmented in time....

it may be a bug somewhere and the MFTzone is not securized...

i didnt try it but...i belive that if u disable superfetch u wont get a mft zone overwrite....cuz the boot defrag wont have a data collector

hey again....

i asked u uper....WHY isnt a problem a fragmented mft ?

just to understaind and all....

win 7 is new to me (and to other millions) and just looking for answers...from my experience....every top defragger(paragon, o&o, perfect disk, diskeeper, ultimate defarg....etc etc) has a "defrag mft" section.....if its not important....i keep asking....why ?

from that link u post it....i didnt find a thing saying that fragmented mft is a normal thing in win 7.....

and i still dont understaind why windows is setup to provide a 12.5% mft zone if the boot defragger still overwrites it anyway 1st time it has the chance

sry if im asking too much but......cant trust ur word....YET
