Oh no, that sounds rough! Losing a partition like that can really be a nightmare. Don’t worry, there are quite a few reliable software options that can help you out.
One of the software that comes highly recommended for this kind of issue is Disk Drill for Windows. It’s pretty user-friendly and has some powerful features that could help you recover your lost partition and the important data on it. Disk Drill can recover files from virtually any storage device, no matter the file system.
I once used it myself when my external drive went haywire, and it managed to recover almost everything I’d lost. Just download and install it, run the scan, and it’ll show you what it can recover. Of course, be sure to save any recovered files to a different drive to avoid overwriting anything.
If Disk Drill isn’t cutting it for you, there’s also Recuva and EaseUS Partition Recovery. Both have good reputations but personally, I found Disk Drill more straightforward.
