C: - My primary drive that has the OS installed
F: - A second HD I added 2 years ago
This computer doesn't have a media reader.
One cable connects to the drive, and then to the wall outlet to supply power. The other cable connects to the back of the HD, and then into the computers USB port. There is no enclosure like there is with my other ext HD's. These were HD's I picked up from someone and wanted to test them before buying enclosures and finding out they don't work.
It looks similar to this: http://www.buy.com/prod/new-usb-2-0-to-sata-ide-hard-drive-disk-cable-converter-adapter/q/sellerid/18700237/loc/101/213907146.html
These are both ATA drives.
I should also note that my (2) external drives that have their own enclosures are rarely turned on. They are plugged into the computer, but I don't turn them on unless I need something off of them.
