PH CS3 files?

Hi I’m having trouble with CS3, 1/2 the time when I go to “save as” & save the file in jpeg or even tiff it saves in a formatt that’s not recognizable. It often takes me 3 or 4 tries before it’ll save properly. Can anyone help?:sad::sad:

scandisk your harddisks.

OK I’m not that computer savvy & have only just bought a new computer with vista premium What is “scandisk”

thanks for your help have done a scan today & hope it’s done the trick.
