I have an external drive F: .
I have some folders with a lot of data in it. One of the folders will open but in that folder are sub folders.
One of the sub folder will not open. It gives me a message that says "You need to format the disk in drive F: before you can use it".
I know the drive don't need to be formated because all other folders are opening fine. I am using Vista 64 bit. How do I fix this? Please help.
