How can I change an expandable disk to fixed size?

Hi,

I've configure my HDDs as expandable but now I like to set them to a fixed size.
Is it possible to change this setting afterwards?

Thanks

Really no ideas?

 

Ok - that's interessting.
I've two virtual machines - one for Windows XP and the other for Windows 7.

On my Windows 7 VM I can simply uncheck "expandable" in the hdd-settings.
On my Windows XP VM the checkbox is disabled.

Does anybody know how I can enable this checkbox?

Btw: I'm using the latest build of Parallels Desktop 6 for Mac.

Next info - after I press reset in hdd-settings alle checkboxes are enabled.

But if I uncheck "expandable" and press apply I get an internal error 0x03.
