Y'know what?
I only read that MS article earlier today while I was at work. And although I upgraded my BIOS when I first got the drive (and couldn't see more than 137GB), I didn't (at that stage) learn about the registry edit that was required!
I've just added the registry string (as quoted in the MS article), so maybe tht will make a difference!
Anyway Tim_Axe, I'll attached that jpeg you were after. Interesting, Disk Manager says it's 157GB of free space, but Partition Magic 6 reported it as 2 lots of free space (1x100GB, and 1x60GB), so PM obviously recognises something in the way of the prtitions that were there.
I'll post this, and reboot, and see if the registry string makes any difference.
Cheers,
Bruce.
