While running your Windows computer, you may receive error notes suggesting that your hard disk drive might have bad sectors. The errors are generally flagged as CRC or Cyclic Redundancy Error(s).
Some visible symptoms are: Some of your files and folders are missing from a partition, some files are unreadable or corrupted, it takes way too long or is impossible to access some files and folders from a particular location, and so on. All these may be a result of bad sector problems on your computer’s hard disk.
What are bad sectors on a hard disk?
Sectors are small divisions of a hard disk drive. And a bad sector on the hard drive is a sector or an area on the drive where data cannot be written or accessed due to some kind of physical error or inconsistencies of parity bits on the disk. Any data that is written or contained on that particular area is likely to get lost or corrupted. Data which is stored on the rest of the hard disk will be unaffected and the disk will considerably be usable as long as the bad sectors are not too many.
What causes bad sectors to appear on hard disks?
Hard disk bad sectors are primarily due to the magnetic fading of the hard drive and certain mechanical faults. Due to prolonged usage, the magnetic areas of the hard disk tend to lose its magnetic properties and thus its ability to retain data on it. Such bad sectors on the hard disk have the tendency to spread across the entire drive and are sometimes non-repairable.
Probable causes of bad sectors:
When these bad sectors spread on a hard disk, it can result in system turning instable as important system files are destroyed. However, data can be recovered and most damages can be corrected by making use of Remo Recover utility.
Retrieving data from bad sectors with the help of Remo Recover:
Remo Recover is a powerful hard disk recovery application that will thoroughly examine all areas that are affected with bad sectors to retrieve all contents from that hard disk. The software will smartly create an image file of the volume that is affected with bad sectors and will extract all meaningful information from that file. You can then manually examine those contents and save them to any healthy hard drive.
There are many additional features of Remo Recover and some of them are listed below:
Step 1: Install Remo Recover and launch it to open its main screen. Select "Recover Drives" option in order to recover inaccessible flash drive data.

Step 2: Click on "Partition Recovery" option to continue with data recovery process.

Step 3: Software will show a list of partitions, select the drive that is affected with bad sectors to rescue data from it.

Step 4: After the completion of recovery process, the complete list of files from the selected partition appears.

Step 5: Save recovered partition data on any desired location using "Save" option using the full version of this tool.
