Can't See External Hard Drive
Hi,
At one point, I had 4 external hard drives plugged into my IMAC and I could see all of them. For some reason, now, I can't see one of the drives that is plugged directly into the back of my IMAC (USB Port), but I can see one of the external drives that is plugged into a USB hub... But no others...???? I have checked plugs, power, etc... I haven't made any major changes. Can anyone help?
Thanks!
