Windows 7: Change a Dynamic/Invalid Hard drive to Valid

06 Nov 2012   #11

Windows 7 Home Premium 32-Bit - Build 7600 SP1

I also have not seen the "invalid" tag. It might have to do with the disk being external, just a guess.

No, it was attached through a eSata port and used as a backup Disk. On a different PC but with the same OS W7 Pro

Hmm, then this is completely beyond me. Maybe there is a hardware problem in the disk - but that is only a guess.

Hi all

I have this sorted, or at least fixed.

I have no idea why W7 on my new PC saw the disk as Dynamic (and Invalid), my Vista Ultimate machine had no problem with it, VU works with Dynamic disks, I believe W7 Pro does not and called it Invalid because it was Dynamic.

Here is what I did, I used a free hex editor called HXD and followed the advice given here.
