Partition recovery after formatting HDD as Windows 10 bootable USB

#1 Post by Billthebutcher » 12 Jan 2018, 12:56

Hi,
I'm trying to recover the partition of a 3 GB NTFS HDD which I inadvertently format as Windows 10 bootable USB.This disk has very important and files that I urgently need.

This is how the HDD is identified in the Disk Management:

However, TestDisk does not display the unalocated partitions. The hard disk seems small.

After a quick scan

The deep scan does not return any recoverable partitions.

Here is my log file:

After Analyse and Quick Search, use Deeper Search.
If your partition is found, set it to P(rimary) and on next screen, choose Write, confirm, BackupBS, confirm, Quit and restart your computer

Hi cgrenier,
Thanks for your help. I've done Deeper Search already. It does not return any recoverable partitions besides the 32 GB FAT 32.
Can you help me further?

Select EFI GPT instead of PC Intel after selecting the disk. If it still doesn't find your partitions, use PhotoRec to recover your data, it will not recover the original filenames unfortunately.
