Therefore all the available filesystem drivers are unable to mount the filesystem as a drive. If the backup boot sector is good (as in this case) simply choose BACKUP BS and press enter.
A common and befuddling problem with computers is the sudden and seemingly inexplicable disappearance of an external hard drive that has been functioning properly. Then you can rule out physical damage that requires repair with specialized tools in a controlled environment. In order to repair the most common problems that cause an external disk to suddenly become RAW we will use Test Disk.
It can be a breathtaking experience to suddenly be told that your data, often irreplaceable pictures and documents, might be gone forever. For specifics, the hard drive’s technical documentation must be consulted. Download Testdisk Disk_Download and run Select Intel and hit enter (there is a slight chance that the partition is EFI GPT if the drive is 2TB or greater in size and at the bottom of this screen it says that Hint: EFI GPT was detected.
