Formatting a drive erases all the data on it, which seems like it would make recovering that data impossible. However, with the right tools and techniques, it is often possible to recover at least some of the deleted data. Here’s an in-depth look at how data recovery after formatting a drive works.
What Happens When You Format a Drive
When you format a drive, the file system information – like the allocation tables – is overwritten. This tells the operating system that the space taken up by the previous files is now available for new data.
Importantly, formatting does not immediately overwrite the actual data on the drive. The contents of the drive remain intact until new data is written over it. This provides a window of opportunity to recover the “deleted” data.
However, the longer you continue using the drive after formatting, the higher the chance that old data will get overwritten by new data. So for the best chance of recovery, you want to avoid adding more data to the drive.
Recovering Data After Quick Formatting
If you did a quick format of the drive, your chances of data recovery are higher. A quick format simply deletes the file system information but does not scan the drive for bad sectors or otherwise modify user data.
Data recovery software looks at the raw data on the drive and reconstructs the previous file system to make the files accessible again. As long as the existing data remains intact, the chance of recovery is quite high with a quick format.
Tools for Quick Format Data Recovery
There are many data recovery tools available that can recover deleted data after a quick format, including:
-
Stellar Data Recovery – Has a user-friendly interface and works with Windows, Mac, and Linux. Can recover from formatted hard drives, external storage devices, memory cards, and some RAID configurations.
-
EaseUS Data Recovery Wizard – Allows you to scan drives for recoverable data and preview found files before recovery. Has physical damage recovery tools.
-
Disk Drill – Works on Windows and Mac. Has free and premium data recovery capabilities. Can recover up to 500MB data in the free version.
Recovering Data After Full Formatting
If you did a full format on the drive, the recovery process is a bit more complex because a full formatting overwrites the file system information and scans the drive for bad sectors. This modifies user data areas that appear damaged.
However, data recovery is still possible in most cases. The key is again avoiding writing new data to the drive before recovery, as this has a higher chance of overwriting old data in a full format scenario.
Tools for Full Format Data Recovery
Some advanced data recovery tools that can recover data after a full format include:
-
R-Studio – A versatile recovery tool for Windows and Mac with features like advanced RAID recovery and corrupted file system reconstruction.
-
Data Rescue – Specializes in recovering data from drives with hardware issues or file system corruption. Works on Windows and Mac.
-
Ontrack EasyRecovery – Has physical and logical recovery tools for many file systems and types of data loss. Has a free trial so you can test it on your formatted drive first.
Tips to Improve Chances of Data Recovery
To maximize your chances of successfully recovering data after formatting a drive:
-
Stop using the drive immediately after accidentally formatting – the less you write new data, the better.
-
Only connect the formatted drive to copy recovered data – don’t install programs or write files to it.
-
Try multiple recovery tools – each one may get different results.
-
For full formats, go with advanced recovery software that can reconstruct file systems.
-
If the drive is physically damaged, you may need a clean room data recovery service.
While you can potentially recover from both quick and full formatting, avoiding those mistakes in the first place is ideal! Always be extremely careful when working with formatting utilities.
