I have an external Western Digital 320gb hard drive that has never given me problems. However the only thing i can think of that has caused sudden problems for this external SATA drive is the bios flash that i recently updated. The drive is recognized in mycomputer, however it doesnt say how big it is or any details about the drive, and this drive has EXTREMELY important data on it. It asks me to reformat but I can't do this because it warns me that all data will be lost!! Any way to get this external drive to be read?
