Changing Partition types in Vista & error message when initiallising new drive

fetster · 20 Jan 2010 at 22:34

I have created a number of 2Tb drives with the GUID partition type using Vista. I have since found out that they are not compatible with my media player if they have this partition type.

I am trying to change them from a GPT to a MBR partition styles using Windows Vista and XP. (XP will not allow me to do anything to them).

How do I change the type of partition in Vista? When I goto format, it does not allow me to change the partition type.

Finally, I am trying to set up a new drive with a MBR partition but when I go into DIsk Management, and try to initialise the disk, I select MBR but I get the error 'Not enough storage is available to process this command' Then the error message 'Logical Disk manager - The device is not ready'. Any ideas what the problem could be?

To convert back to MBR you'll need to backup the contents of the disk and repartition it I'm afraid.

Backing up is not a problem but I wasn't sure how to repartition in Windows Vista. I tried reformatting, thinking that it would give me the option to reset the partition but it wouldn't let me.

I think you may have to delete all the partitions then re-initialise the disk in Disk Management by right clicking on the grey bit with the disk name rather than clicking in the white bar to the right.
