I've upped the size to 200GB and it makes no difference - tells it's created a
PR successfully then when I check tells me no RP has been set.
The other drives are 1 external hard drive and 1 usb stick. All my work is saved externally the only things on the HDD are what came with the pc and my programmes. I haven't created a RP for the other drives but switched the protection on in case it made a difference there are off again now.
I would just feel more comfortable if I could get it work as it saved me a couple of times on my old PC.
