Thanks for that SD, I'm grateful to you.
All I have to do now is find a drive that doesn't cost an arm and a leg!
As mentioned, it is a while since I bought a hard drive and when looking at a well known online retailer's site, it seems that they all have huge capacity. I shall never use 320Gb let alone 500gb or 1Tb. It's not only MacDonalds who do 'Supersize' portions!
Thanks again,
