I pulled the hard drive (3.5") from an older computer that did not have USB ports. I have data on the drive that I wish to keep! I purchased an external hard drive enclosure so that I could use this with my current computer (uses Windows XP). I installed the hard drive into the enclosure - it uses USB to run. The computer recognizes the drive. When I go to Windows Explorer, this drive shows up as “F: Local Drive.” When I double-click on it (or use the mouse to Open), I get a pop-up box that asks me if I want to format the drive. I respond no. So… I cannot access the files I have on this drive. I am assuming that formatting will erase all data. Any suggestions on what I am doing wrong? I just want to be able to open the drive, and intend to copy files to hard drive of current pc.
