Can't shrink C://

WebmasterWorld Senior Member 10+ Year Member

Msg#: 3710098 posted 9:54 am on Jul 29, 2008 (gmt 0)

Bought a new laptop (Toshiba) with Vista 32bit SP 1.

Shrink C:// (actually 110 Gb with Vista approx. 15 Gb) and Windows can only free 30 Gb of space.

Step A/ Did the basic, DiskCleanup and Defragmentation.
Tried again - same result

Step B/ Download PerfectDisk 8, did a Defragmentation (with offline files - pages files, - after boot)
Gain 10 Gb but still not enough.

Step C/ Did a factory restore, then Defragmentation with PerfectDisk and can free 43 Gb of space.

I have read a lot of docs about this issue and only two others solutions came out

A/ Because whatever you do, MFT files will always be in the middle of the volume, a method would be to do several restore/shrink. E.g. Shrink C and create new partition (50%), do factory restore in C and shring it again to free space, and again up to the maximum limit

B/ Force to delete user files before defragment/shrink - e.g. DiskCleanup Wizard, remove hibernation file and restore points, disable System Restore, disable the pagefile, disable the kernel memory dump, reboot machine and delete your c:\pagefile.sys file. I want to try this one but it is a bit risky, isn't it

Any of you this the same issue and a solution ?

Thank you

Guys ! I really need some help on this issue.

I did the above and now I have

C:/ - 35 Gb
D:/ - 43 Gb
Free space - 35 Gb

I can not extend the D:/ to add free space !
What should I do to add the free space to D partition ?

What will happen if I delete D:/ ? Will it become free space ?

Any tip on this issue will be highly welcome !

Format the drive entirely, partition it as you want it, then install Vista :-S on the partition of your choice.

Gparted does a very good shrink of NTFS partitions. Try that too.

Thanks Vince for your answer. Much appreciated.
I am a total newbie in OS :)

I will try the application but a suggestion without the need of external software would be better.

Anyway, it seems that it is a basic/dynamic problem. And secondly, it seems also that partition should be adjacent to free space in the Disk Management to be extended (but it is in my case)

Before you attempt to extend a simple volume, there are a few things you need to keep in mind. A primary partition becomes a simple volume when the disk is converted from basic to dynamic. However, if the simple volume was created before the disk was converted to dynamic it can not be extended. A simple volume can only be extended if the simple volume was created after the disk was converted to dynamic. A simple volume that was originally a primary partition can not be extended and you can not extend the system or boot volume.

From what I have read, turning a DATA partition (partition only used to stored data and application) into dynamic is stupid !

Went to Vista website and saw this
When you delete a hard disk partition or volume (the terms partition and volume are often used interchangeably), you create empty space that you can use to create new partitions.

So I will try to delete the D:/ partition hoping that both free space can be allocated into one single new volume.

I do not have any data yet, so it's not a big deal...

If it doesn't work then I will use Gparted. Anywaym, will definitely report back here tomorrow.
