Rescue Data from Hard Drive with Bad Sectors

 

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:

• Mechanical faults may include physical shocks to the hard disk
• Abrupt power shutdowns, spikes and failures
• Disruptions during read-write operations on the hard disk drive
• Header crash can also be the cause behind bad sectors and may lead to permanent data loss on it

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:

• Remo Recover is an advanced hard drive file recovery utility that is capable of retrieving all types of data files from all types of hard disk drives. It can identify files of more than 300 different file extensions including all famous audio, video and picture files, various types of documents, archives, softwares and many more
• This tool can recover all contents that are deleted or lost, irrespective of the actual reason behind data loss. For example, Remo Recover can be implemented to restore external hard drive not recognized, restore files lost due to hard drive file header corruption, hard drive format, etc.
• With this app, you can easily perform data recovery from bad hard drive on Mac under various data loss scenarios.

Steps to recover data from hard drive with bad sectors using Remo Recover:

Step 1: Install Remo Recover and launch it to open its main screen. Select "Recover Partitions" option. Then, you will see a list of logical and physical drives available in the system. Choose the appropriate one and click "Scan" button.

Step 2: The software scans the drive now to find the partitions that were present in it. Once scanning is over, a list of found hard drive partitions are listed. Choose the partition from where you want to recover data and click "Scan" button to initiate the recovery process

Step 3: Once scanning is completed, a list of recovered files are displayed in "Data View", and "File Type View"

Step 4: Now, take the advantage of its "Preview" option to preview each of the recovred files and evaluate its recovery results before saving

Step 5: If you are completely satisfied with the recovery results, then purchase its complete edition and save the recovered files
