Replace the Disk with a Good/Bigger OneWhat to do when a hard disk has a bad sector problem in Windows 10/8/7? Occasionally, when one or more bad sectors come upon on a good hard disk, the disk will go bad. When this happens, the data in those bad sectors may be lost, but the data on the rest of the disk will be unaffected and the disk is still completely usable. Those bad sectors cannot be repaired, but they can be marked as unusable. Once marked as unusable, the Operating System will know not to attempt to store data in those bad sectors.
The total disk capacity will be decreased by the amount of storage space in those bad sectors. If the bad sector was caused by a faulty drive head, the problem can spread to many other sectors across the disk.So, if your hard drive is experiencing one or more bad sectors, follow our instruction to fix your problem as soon as possible.
