Windows Defrag vs Smart Defrag

[demitris]

hi everybody

 

solbjerg i had launched checkdisk/f a week ago so the reason for recovering free space is not this

 

what i believe is that smartdefrag uses methods for compact packing of files in deep optimization and the microsoft OS at first boot relaxes selective important system files for some reason

 

cheers

Did you check if the MFT enlargement space is changed? It may have been decreased.

 

NOTE: chkdsk /f does not check the empty space, but chkdsk /r does.

Hi enoscype

 

do u mean that deep optimise defrag MFT and PageFile ?

as i know MicroSoft suggests this defragmentation to be done during booting otherwise is not safe on-line.

 

even though it sounds strange the recovering of 1.9 Gb given that i am below than a medium user.

 

And what about the decrease of 0.7 Gb immediatety after the first loggin when the system worked extensively on hard-disk producing a hissing noise.

Hi demitris

I meant chkdsk /r - and I meant to run it just prior to the defragmentation with as little as possible running automatically in the background in order to achieve the best possible defragmentation.

 

Τίεὔκολον; Τὸἄλλῳὑποτίθεσθαι. (What is easy? To advise others.)

Thales must have been a bit pissed off at smart-alecks when he said that, because in reality it is even harder to give good advice to others - it requires vast knowledge - and even that you know yourself.

Τίδύσκολον; Τὸἐαυτὸνγνῶναι. (What is hard? To know yourself.)

And this he correctly states is very hard :-)

This would seem to exclude me from giving advice :-)

Hi demitris,

 

No I don't mean MFT, I mean reserved space for MFT enlargement (MFT Zone).

 

Please have alook at the images in the first post of Think about Defragmentation!!! thread.

 

I have noticed that some defragmenters decrease the size of that area in NTFS systems much below 12.5% of the total size (Default size) of the disk .

 

Cheers.

hi enoskype

 

ok u mean MFT zone

I thought this was considered free space although was reserved as 12.5% by default

 

but can you guide me where to check its size through windows since in smartdefrag i can't find any option (Smartdefrag 2.1)

how did u get those reports (images)?

 

cheers

Hi demitris,

 

A)

MFT Zone size is defined in the following Registry Entry:

 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem

Look for the Value Name NtfsMftZoneReservation. If not present and wyouwould like to change,

1. From the Edit menu, click Add Value.

 

2. Type the following information in the dialog box:

Value Name: NtfsMftZoneReservation

Data Type : REG_DWORD

Data : (valid range is 1-4) (1=>12.5%, 2=>25%, 3=>37.5%, 4=>50%)

 

3. Quit Registry Editor and restart your computer.

If there is no such entry, then it is default as 12.5% in XP.

 

B)

The images are for my XP Pro drive. The screenshots are taken just after the defragmentation. I belive there is information in that first post.

Please read much as you can in that thread to have a better idea of defragmentation and what different defragmentation programs do including Smart Defrag.

Please ask again clearly if you feel the answer is not fit for your question.

 

Cheers.

hi enoskype

 

My OS is Vista Home premium sp2

 

i got in registry editor and found the entry

 

Name NtfsMftZoneReservation

Type REG_DWORD

Data 0x00000000(0)

 

Using right click there was option modify binary data . i didn't use it of course and i entered whithout privelage.

 

does this mean i have no MTF zone ?

 

cheers
