Eventually if you use a computer long enough you will have to deal with a hard drive crash. The basic solution for repair of a hard disk drive that has suffered a logic crash to is to reload your Windows operating system. However doing this formats your hard drive and formatting your hard drive deletes all of the files stored on it. This leaves you two options. The first is to use a data recovery program connected to this hard drive by means of a second computer and direct that computer’s operating system to copy from your crashed hard drive all of the files.
The second option is to go ahead and reload your operating system knowing that it will reformat that drive. Data recovery after reformat of hard drives is very possible. To recover data from formatted drive partitions you will need a file recovery program that treats those formatted drive areas as if it were deleted files. Most of the better data recovery utilities perform in this manner.
