That a hard drive begins to fail and throw error messages is sometimes unavoidable for any computer user. And when this unfortunately happens, the first question that comes to your mind is: “Can it be repaired?”
You will find options to repair and remove bad sectors in Windows 10/8/7 and Linux, both on an external storage device and on a hard drive, without losing Data Recovery Services.
If you can’t access Data Recovery Services on your PC or USB drive due to bad sectors, follow these steps to restore data and repair bad sectors later.
This buggy little pool of storage space will not respond to any read or write requests. These sectors can be of two types: one resulting due to a software error and one due to physical damage.
Occasionally, when one or more bad sectors appear on a healthy hard drive, the drive will crash. When this happens, the data in those sectors may be lost, but the data on the rest of the drive will not be affected and the drive will still be fully usable.
Those bad sectors cannot be repaired, but can be marked as unusable. Once marked as unusable, the operating system will know that it will no longer have to store Wikipedia data on those bad sectors.
The total capacity of the disk will be decreased by the amount of storage space in those bad sectors. If the bad sector was caused by a bad head, the problem could spread to many other sectors across the drive.
Therefore, if your hard drive is experiencing one or more bad sectors , it is recommended to back up the drive immediately and repair or fix these sectors as soon as possible.
