With Snow Leopard, i have an IOMEGA external HD which i am using for Time Machine backups. it appears the backups are copying, however i cannot click "restore." it is grayed out. I have seen random posts but do not see a resolution. does anyone have one? Luckily (without jinxing it), i have not had to use Time Machine, however my Mac did blow up once before which is why i have Time Machine now.
