Hiii.
Formatting the partition will delete my data resides in the volume ,
So with out deleting data ,,how can I change the cluster size..?
Copy data away
Format volume in new cluster size
Copy data back

Not possible to re-size the cluster with keeping all data data…???(with out taking backup)
Actually is there a need to to copy the data of that particular volume into another volume and through formatting the volume to change cluster size…?
hiiii..
We can't resize the cluster with the existing data.....??
But I've heard some third party software do this thing without formatting or taking backup...
Have you tried that software? Anything is possible. You might get source
code access to Windows and see if and how it could be accomplished, though
any attempt to do it on a mounted volume would be very difficult. Without
the source code access, it will required months of reverse engineering.
There are some Linux drivers for NTFS, but how close to being correct those
implementations might be is a question you need to answer.

Yes I've tried ......
I works properly.... within seconds (3 or 4 seconds)... So they do not do formatting ...backing up processes.. The product name is Acronis disk director......And I send the software to you...if you wanna see..it's performance... install and check it out........
Ah… This Guy is talking about Acronis.
IIRC, you can resize the volume using Acronis from its boot disk. Right?
Atleast it does not support resizing of system volume from within a running
OS.
This essentially implies what David said about mounted volumes- It would be
hard to do.
But Acronis uses boot disk to achieve this!

You’ve asked this question many times, several different ways and you’ve yet to get an answer. I think it might be time to consider the possibility that you’re not going to get an answer to this one, for whatever reason, and move on.
mm
Mr...Ayush Guptha you are mistaken....
I'm not using Acronis boot disk... I use Acronis Disk director suite... While running the Windows not at boot time ...we can re-size cluster.....
Can you resize even the system volume (the one on which the OS is installed)
while running Windows?

Ayush Gupta

I don’t know how the Acronis product works exactly, but are sure that it isn’t queuing operations that will be executed by a native application next reboot? That’s how PartitionMagic used to work, if I recall correctly.
Also, I found this on Acronis website regarding Disk Director:
Change Cluster Size ? change FAT16/FAT32 partition cluster size
I don’t know if that’s correct or current, but it doesn’t sound like NTFS is supported.
mm
Mr...Ayush Guptha....
I've tested with only y...Logical partitions.....In Logical case it works fine ....
In the case of primary volumes it will work with boot mode ....
So… then it’s not a big deal!
Just start going through the FAT32 document present on Microsoft’s site to
understand the on-disk data structures involved.
But again, as MM (Martin not the Memory manager :P) has already told you,
this would be hard to achieve for NTFS since the on-disk structures of NTFS
are undocumented. If you want to rely on the structures that have been found
out by reverse engineering, go ahead!

Okkkk…Mr.Ayush Gupta …thanks for the useful information…

>> I works properly… within seconds (3 or 4 seconds)… So they do not do formatting …backing up…
I think Work properly is magical here,
To achieve the stated, They might have just changed the value of sectors per cluster and few other fields at PBS and at some other locations. Also if they are not reorganizing the drive than I think they are not touching existing files. They could be using some tricky implementation where they will not touch the existing files but will change the cluster value stored at some XYZ location which FS and other related tools depends on.
for instance,
if previous cluster size is 2 sectors, i.e. 1024 bytes, than a 10 bytes on disk size would be 1024 bytes.
if changed cluster size is 8 sectors, i.e. 4096 bytes, than a 10 bytes on disk size would be 4096 bytes.
As they are not reorganizing the files, they’ll leave old file with disk size as 1024 and will create new file with 4096 bytes.
I may be wrong here as I have not yet used said software. But operation time as 3-4 sec leaves no room for file structuring and convincing me that older files should be on old cluster size itself.
Thanks
Aditya
You are correct .....
They uses some tricky implementation to perform the task......
Can we spy the processes happening....???
>>Can we spy the processes happening…???
IMHO you should refrain yourself from asking any such thing here or any where. You can reverse engineer what ever you want but instead of that I suggest you to read FAT docs and available references on web. Than try modifying related field at several locations and see if you can get the expected.
Thanks
Aditya
For FAT you have all the documentation you need. All that is needed beyond
the fatgen103.docx is some thought. Write some user mode code to read a FAT
system sector by sector and examine how everything is related. Then think
if you change the cluster size, what that would impact. Then how can you
change the cluster size, get the data in the correct locations, and maintain
the old information until the end so you don’t trash the user’s data during
a power failure. Those who have done all of this may be available for hire
if you want something in less than six months to a year. If it is the boot
or system volume, then the issues also involve allowing normal activities to
occur without failing. All other volumes can be done under lock to your
program exclusively.
