I had to use kennytech's suggestion to get it working.I've tried running 7.2.2 using trouble shoot compatibility, this managed to get it to install using XP SP 2 compatibility mode. But does not see my OS X partition, yet can read the HSF side of the Leopard disk. How did you get it to work? (using 32 bit Windows 7 BTW).
Edit: Just realised haven't assigned it a drive letter, d'oh. Will Check Computer Management and see if I can.
Edit 2: Nope that didn't work, can see partition in Computer Management but Windows doesn't know what to do with it
