CheckDisk is a free tool used to repair hard disks.
If you have a problem with a hard drive, try repairing it first with this free tool before paying for expensive programs or giving the drive for lost. CheckDisk will scan the disk for damaged sectors and can either repair them completely or hide them so that the computer recognizes the disk and can read it without problems. The only thing you'll notice is a loss of hard drive capacity. The program has access to the files that are in that sector to recover them and not lose them.
Before giving for lost a damaged sector this program will analyze all the possible solutions to try to recover the disk completely and not lose storage capacity.
