What we're speaking about?
Reallocated sectors are specific 512-byte sectors of the hard drive that no longer have sufficient secure storage capacity. When the hard drive detects an error while writing, reading, or checking data during operation, it makes this sector unallocated, and moves the data to the reserved sectors on the disk. Thus, the hard disk will help you protect data from damage and deletion - your data will be moved to a safe part of the disk, and the disk itself will continue to work without interruption. However, it should be understood that if you lose even one sector containing part of a larger file (photo, video or text document), you will no longer be able to open these files, because the file is no longer integral. A hard disk with reallocated sectors can still work for a long time, but if the number of reallocated sectors increases at a high speed, this is a bad sign, you can lose the disk.
Therefore, the question may arise: is it safe to continue using the hard disk with unallocated sectors?
It really depends on how much you value your data. Of course, if there is nothing of value in there, or the drive is being used for testing applications and services, you may well be using this hard drive for the rest of its life. But, if there is valuable information for you, then it is better to replace such a disk with a new one and sleep peacefully. And, if you have extremely important data on the disk, even one reallocated sector should become a reason for you to replace the hard disk or at least to create an additional up-to-date backup of your data. Auchshe spend a little money and their efforts, rather than risk your job.
If you still haven't replaced the hard drive with reallocated sectors and lost data, you still have a way out.

So, how to fix this issue?
The only and correct "solution" for the reallocated sector is to buy a new hard drive after you restore data using DiskInternals Partition Recovery. Do not even try to somehow fix the reallocated sectors - this is a waste of time, the hard disk will no longer use these sectors and will continue to work without saving data in this part of the disk. There are no software or hardware fixes to reduce the number of reallocated sectors.
Only after you back up your data, restore your data and buy a new drive can you hack the hard drive for your own purposes.
