Recently removed the VistaPE partition from my eSATA as I am now booting the VistaPE ISO directly with Grub4DOS. However I had overlooked the fact that the VistaPE partition was the only primary partition on the drive, and now when I run DD10, either in Vista or from the CD, the eSATA drive is no longer listed. Seems DD10 requires at least one primary partition in order to 'see' a drive. I have tried shrinking the single extended logical partition using Vista's Disk Management in an attempt to create sufficient space to create a new primary partition, but it said it could only shrink 540MB and having accepted that I still don't have any unallocated space to work with. I need to get this drive up in DD but atm cannot think of any way this can be done.
