I took the 30GB harddrive out of my old zune planning on using it as a usb drive. I bought the appropriate enclosure, put it together, plugged it in and planned to format it and be done... little did i know it uses GPT partitioning. It doesnt necessarilly have to be formatted to NTFS, i believe most usb drives are FAT32?? Anyway, Windows sees the drive as a usb device, but nothing more. It will not allow me to format it or do anything with it. I have tried disk management (it says its not ready when i try to "initialize disk"), windows xp recovery console (tried "diskpart"), also tried diskpart while in windows, and gparted in ubuntu... nothing can do anything with it. This is very frustrating to me because i waited 3 weeks for the enclosure to finally arrive. If anyone has any suggestions that would be great. Thanks. Also, the drive is plugged into the enclosure correctly. I made that mistake the first time and the LED didnt light up. I switched it, and now it lights up correctly and windows sees it.
