Disk Management has stopped working

Hi there. I'm trying to use the Disk Management app built in to vista to
shrink a partition on one of my hard disks, however every time I try to run
it from the computer management utility in administrative tools it tells me
"An internal error has occurred. Restart the disk management snap-in".

When I click ok to get past the window it then opens the app, but when I
right-click on any drive & choose "shrink" it tells me the program has
stopped working and quits.

It's the only part of Vista i've had any problem with, I've tried restarting
it, rebooting pc, and starting the disk management app on its own
(diskmgmt.msc) from the search box. If anyone has any idea what's doing wrong
I'd appreciate any info you can give!

Thanks

Hello,

This means that the disk management program crashed, possibly due to a
bug in Windows or a misconfiguration somewhere on your computer.

The first thing i would do would be to send the error reports to
Microsoft and see if they have any added info on your problem:

- Click start
- Click Control Panel
- Click System and Maintenance
- Click Problem Reports and Solutions
- Click "Check for new solutions" on the left

Another thing you might try is to use the "diskpart" command-line
utility, which is a command-line version of the disk management
console.

You need to run this utility from an elevated command prompt.

- Click start
- Type: cmd
- Right-click cmd and click Run As Administrator
- Type: diskpart
- Press enter

You are now inside the diskpart utility.

1- Select which volume you wish to shrink

- Type: list volume
- Press enter
- Type: select volume X
(where X is the volume # that you want)
- Press enter

2- Shrink the drive

- Type: help shrink

This information will tell you how to tell diskpart how you want to
shrink the volume.

To see the most you can shrink the volume by, type:

shrink querymax

As an example, this command would shrink the volume by 5 gb:

shrink desired=5120
