How to recover system's data ?

Some damage can be repaired by replacing parts in the hard disk. This alone may make the disk usable, but there may still be logical damage.

f you have emptied the Recycle Bin, you can try to recover an older version of the deleted or lost file by using the free backup and restore feature built into Windows. To do it:

Open the folder that used to contain the deleted file and click the "History" button.

"Previous" button to locate and select the file you want to retrieve, then click the "Restore" button to get it back.

A specialized disk-imaging procedure is used to recover every readable bit from the surface.

Once this image is acquired and saved on a reliable medium, the image can be safely analyzed for logical damage and will possibly allow much of the original file system to be reconstructed.

A common misconception is that a damaged printed circuit board (PCB) may be simply replaced during recovery procedures by an identical PCB from a healthy drive.

While this may work in rare circumstances on hard disk drives manufactured before 2003, it will not work on newer drives.

Electronics boards of modern drives usually contain drive-specific adaptation data (generally a map of bad sectors and tuning parameters) and other information required to properly access data on the drive.

Replacement boards often need this information to effectively recover all of the data.

The replacement board may need to be reprogrammed.

Some manufacturers (Seagate, for example) store this information on a serial EEPROM chip, which can be removed and transferred to the replacement board.[4][5]

Each hard disk drive has what is called a system area or service area; this portion of the drive, which is not directly accessible to the end user, usually contains drive's firmware and adaptive data that helps the drive operate within normal parameters.
