As with many similar situations in life the appropriate response is “Don’t panic”. Sometimes that information is difficult to come by and can be proprietary. If that is the case, select EFI GPT instead and try that.) Press Q to go back a screen and then press enter to get to this screen.When approached sensibly and carefully, the situation can be resolved and the data saved more times than not. For example, the formulas for how some manufacturers calculate normalized values for attributes can be very difficult to find. Select WRITE and press enter in order to write our new partition table to the drive.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.I have a love-hate relationship with my home server.
In any case we recommend to check hard disk size next to Disk /dev/sd X at the output’s beginning so that you make sure that you select the exact hard disk that boots initially in your machine.A RAW filesystem simply means that it is a filesystem that is not recognized by Windows. DATA AND CALCULATE VALUES AND TOLERANCES DIFFERENTLY. When this is the case Test Disk will stop at this point and ask you to fix it before it finishes writing the new partition table.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.These examples use techniques that I actually employ in the real world to deal with real problems. I take no responsibility for anything you do based on my examples or the information that I provide here. After making sure that the connection between the drive and the computer is correct and its quality is the best it can be, you need to check the health of the drive itself. If there is no indication of physical damage then you can continue. If you try them yourself, it might cause damage or irreparable loss. If there is physical damage, then consider sending the drive to a professional recovery service since physical damage often continues to degrade the data and simply powering on the drive may make data become irretrievable.
