Hi Jaclaz, Thanks for your response. Additional info below: Which OS are you running? > Windows 7 Is it an internal or external disk? > External How exactly (under which OS and with which tool) was it originally partitioned? > Windows 7, disk management Which was it's use (i.e. a backup drive, a "main" drive, almost empty, almost full, recently defragged, etc)? > it was connected to an all in one touchscreen desktop (HP touchsmart), and was storing recorded tv programs and was also a repository of pictures and videos. I will be buying a HD to clone the original disk into. Will buy Western Digital this time!
