Is there a way to defrag the MFT file and inode data?

  • Thread starter Thread starter Antonio Perez

Only mentioned FAT in an effort to say that defragmenting a NTFS partition
is far more effective in really reducing the number of fragmented files then
worrying about an MFT split into 3 parts.

Not many users of Windows XP would find choosing FAT 32 over NTFS a better
choice. There is no MFT file in FAT32. MFT is a product of NTFS! I am not
sure why you have introduced FAT32 to this debate.

The originator of this thread refers to "inode data".
"A data structure holding information about files in a Unix file system.
There is an inode for each file and a file is uniquely identified by the
file system on which it resides and its inode number on that system. Each
inode contains the following information: the device where the inode
resides, locking information, mode and type of file, the number of links
to the file, the owner's user and group ids, the number of bytes in the
file, access and modification times, the time the inode itself was last
modified and the addresses of the file's blocks on disk. A Unix directory
is an association between file leafnames and inode numbers. A file's inode
number can be found using the "-i" switch to ls."

Inode data seems to be specific to Unix not Windows! Odd that it should be
mentioned in the Subject of this thread.

It's not.

And if you were using FAT32 instead of NTFS and had the same files as
Gerry has on his partition then you would really see some significant
fragmentation (not reported but the fragmentation is there) because
of the folders splattered all over the partition and the way some
defragmentation tools ignore folder clusters and sandwiched a single
file between three of four folders.

You are missing completely the point here, the explanation i've
read in painful detail somewhere else.

The point is: What to do _after_ is fragmented...

After all that work, and assuming you increased the
NtfsMftZoneReservation before reformatting the partition, when you
run defrag.msc and run Analyze to look at the report, what is the
value for "Percent MFT in use"?

Was all this effort for a data-only partition? Or did you somehow
do all this for the partition containing Windows?

With Windows 98 it was much more of a game trying to ensure Disk
Defragmenter was not constantly restarting. Of course safe mode was the
answer. Occasionally people still recommend defragmenting in safe mode
but I have never seen the need to do so in Windows XP.

Total excess fragments = 1
Average fragments per file = 1.00

Of course they are all large files (ripped DVDs).

The average file size on my my windows partition is 404 kb (49,622
files). Your's, albeit not a windows patrtition, is 444 mb (2,821
files). So there's quite a difference between them <G>.
