The Mac is up and running, even the add on external drive. I know it's overkill, but my next door neighbour has just bought a very ordinary looking saloon car with best part of 600 bhp.. So my new set up might be over the top but only cost a couple of grand, I can use my set up, all he can do is lean on the bar and brag about the size of his.. Anyway that's not the point. Memory sticks......... Mine worked fine, then suddenly zilch. Well almost., it appears on the screen showing one picture. If I look at the "info" it shows 15Gb used and about the same available. Any ideas? I wouldn't normally bother but......and it's a big BUT. The stick contains all my wedding photographs,I had copied them from my old computer to transfer to the new Mac prior to printing. Initially when I checked they worked but now, Oh dear, I can see trouble looming.
