Hello, here is my situation. I have an external usb WD hard drive. I owned a MAC for a while (I know, I know), so it was formatted Mac. Then after I bought a PC again, I used a program on a FRIENDS LAPTOP, called Mac Drive, to take all the stuff I would be keeping off of it, and then I attemped to format it, after which I was going to put all of my stuff back on it. A quick format would not work, kept saying that it could not complete it, so I did a regular format, waited and waited, then at 99%, could not complete. After this I noticed tho that it was showing up in "My Computer", so I was like awesome. I put all the files back on it and everything seemed great. But when I plugged it back into my computer, no such luck. If I go into Device Manager, it is under Disk Drives. But there is no drive letter assigned to it. Any help on this would be great, thanks. I'm running XP Pro, SP2.
