I have several questions here, and I hope someone can provide me with the best solution .
As a user of PC, how can I recover my data when my hard drive crashes?
If the crash is not big, is it possible to recover the data trapped in the bad sector. And may I know if it is possible to fix the bad sector?
If possible, how can it be done for a cheap cost??
I have once seen that the scan disk of the Windows OS can fix some of the bad sectors. Is this true?
I have a hard drive of Samsung with a 250 GB which got some bad sectors, so it's urgent. Please give me an answer.
Bad sectors maybe due to a physical damage or inconsistencies in parity bit. If your hard disk is physically damaged, you will need to consult a data recovery expert. Otherwise, if you’re running a Windows 7, right click on the disk drive >properties>Tools>error checking; then check all the boxes and start the process. For windows XP and Me, go to programs>accessories>scan disk.
You need to back up your data to avoid further loss. Then, you can look for a hard disk recovery software such as Digital Rescue 3.1, R –studio, Recover my File. Most of this data recovery software costs a penny .
If all else fail, full format your hard drive to prevent further loss of space and also to recover those sectors.
To recover data after a hard disk crash, I suggest you to buy a new hard disk. Install it as the master drive. Then, your bad data should be installed as a slave data. Install the version of the operating system that you had in the previous hard disk. Find suitable data recovery software such as Easy recovery or Easeus Data Recovery. Using the professional version of these tools, you can recover your data only if your hard disk has not suffered any physical damage. Either way, repair the damaged components by taking the disk to a qualified technician.
Another way is to determine the nature of the crash. If it's software related, use the windows or any other operating system boot disk to start your computer. You can access the files from there, then back them up in a USB drive and then reinstall the operating system again.
One crazy suggestion is to place it overnight, into a very cold dry place particularly a freezer. It has been reported to have worked. But I do not advise it to you. You can do it at your own risk.
