I have reinstalled Windows and all of my software, but I forgot to back up all my pictures before reinstalling Windows OS. Can I recover data after reinstalling Windows?
It might be possible. It really depends on how much data you had before you reinstalled Windows OS and how much data you have written since.
When you reinstall Windows, it formats the drive. This takes all the clusters of data and marks them so they can be overwritten. The data is still on the drive after the format and can still be retrieved. The damage happens when you reinstall Windows. You need to download a data recovery software called M3 Data Recovery Free, it can recover lost data due to deletion, format, partition loss, Windows reinstall, hard drive crash, virus attack, etc.
When you get to step 3 of our software, the first thing that people assume is that since they can see the file name, the data is recoverable. This is an incorrect assumption. In the NTFS file system, the file's name, size, date, time and the clusters used by the data are stored in the Master File Table (MFT) entry.
If those clusters have not been overwritten by the re-installation of Windows, then the file will be recoverable. However if the re-installation of windows has written anything to these clusters, you still have a chance to recover data after reinsalling Windows.
It doesn't take long before the data would become overwritten, so if you ever lose a file, don't do anything! Install an data recovery program on a separate disk ASAP to try and recover data after reinsatling Windows. Remember, if you install the data recovery software on your hard drive you run the risk of it overwriting the file you want to recover.
