How to Recover Data from Erased Hard Disk?
Recover hard drive: If your hard drive has valuable information, but you can’t access it, because the drive has been erased or damaged, there could be that the data is recoverable.
Actually, when you delete a file, Windows doesn’t erase it. It just marks the sectors containing the file’s data as available. They are thus considered free space. Now, a file recovery program can scan a hard drive for deleted files and restore them. However, if the file has been partially overwritten, the file recovery program can only recover part of the data.
To recover erased files from your hard disk, first, take a look at the drive. If everything looks good, you can proceed and try to restore data. There exist a few really good tools which will help you in the process. For example, Recuva utility makes data recovery simple. It browses and restores selected files off of the drive. Another similar tool is Undelete Plus for Windows. For Mac users, File Salvage is one of the best tools to pull data off. This utility can recover virtually any type of file on multiple partition types. It can recover from damaged drives and corrupt media. Another powerful tool is Data Rescue for Mac, but to get it, you must pay considerable fee.
On the contrary, TestDisk is an open source utility. TestDisk can run against almost any platform or partition type. It recovers data quickly.
These and other tools can recover from reformatted drives, especially if the data hasn’t been overwritten. Anyway, the less you work with the drive, the better. The more you write to it, the more likely you are to overwrite data. Even when you read from the damaged drive, you run the risk of exacerbating any damage it may have.
Don’t forget to back up your computer before you plug your damaged or erased into your PC and boot up.
Finally, remember that if you’re not careful, unscrupulous people can recover your confidential files, even if you think you’ve deleted all your data. This concern is even more important when you’re disposing of a computer or hard drive.
