Resizing Windows partition

Postby mikejd » Sun May 08, 2011 3:16 pm

I am trying to resize a Windows XP partition so I can install openSUSE to dual boot.

I have run the Windows defrag and then run the install. When setting up the partitions it offered a Windows partition resize of about 172GB despite there only being about 20GB of files.

So I downloaded a third party defrag progam, Raxco PerfectDisk, which I had seen recommended. Ran this and it defragged the drive, both immediately and at reboot. The install still only offered a resize of 164GB. Looking at the cluster map I think the reason is some Metadata located near the middle of the drive. PerfectDisk doesn't move this to close up free space.

I also tried another program, Puran Defrag, which did appear to close up the free space but still didn't move the metadata.

The cluster map shows:
Block 1 - Directory
Blocks 2-18 - free space
Blocks 19-161 - files
Blocks 162-560 - free space
Block 561 - Metadata
Blocks 562-1011 - MFT zone
Blocks 1011-1800 - free space
Blocks 1801-1802 - Metadata

It seems a waste to have such a large partition for only about 20GB of files. Can anyone suggest how I can reduce the partition?

You don't say what size the partition is, but ISTR there is a limit to how far you can resize an NTFS partition in one step. If the size you are offered is around half the original size, accept the resize, then reboot, defrag, rinse and repeat.

It may be worth trying Partition Magic which comes as a Live CD with a wide range of tools.

I always used to disable the virtual memory in windows, when I had it, before defragging as well. That would sometimes allow a greater shrinkage of the windows partition.

Remember to enable it again after doing this, or you may find your windows running more slowly.

nelz: the original Windows partition is the full disc - 465GB. Can I just resize the partition using the SUSE installer, then exit and go back to Windows to defrag and resize again?

Yes, although you may have to do this more than once to get the size you want.
