I started using it to recover the files, it estimated about 16 hours to move the files. The TestDisk program also came with a data recovery program. I had the program display the list on the drive and all the folders and files appear to still be on the hard drive. The harddrive has no partitions though, its just one big drive. I downloaded a program called Test Disk which is made to find damaged partitions and read the drive.
The computer I'm using is a Hp with Windows XP. I tried plugging it into a different usb port and i tried plugging it into my other computer, which is a Sony with Window XP, and it still didn't work. I assume reformating it would erase all of te information I have on it so I didn't do it. When I turn it on, Windows assigns it a letter and I can see it under My Computer like normal, but then when I click on it, it says the drive is not formatted and asks me if I want to format it. Recently, I ran into a problem accessing it. I have a Seagate 160 GB External Hard Drive that I've been using for about 2 years or so.
