Windows 11 reset - data lost

April 6th, 2023, 6:22

Hi to all members.

I restarted windows 11 22H2 to factory settings but by mistake checked delete user files (thought just SSD with system is going to be deleted and not secondary HDD with data)
Second HDD is WD5000AAKS.Tried few popular programs (disk digger, recuva, file scavenger, stellar etc...)for recovery but they find just some unknown and unreadable files.
I guess that new windows version write zeroes to distroy data and to be unreadable.Do you think there is chance to recover any data from it ?
Disk is used as secondary and no data is written to it after restart.

Thanks in advance :)

windows install does not wipe disks.

wasn't it bitlocker-ed by any chance? those progs should be able to find at least some working data in raw rec mode if it wasn't crypted...

PC was using win7 for years and working fine.I fresh installed win11 , but windows security was not working (tried all fix but no luck), so I thought factory reset would fix things.It's older PC DDR2.My opinion is that new Win11 now after factory reset delete's data unrecoverable.My mistake on factory reset or restore how ever it is called i checked delete my data.

i really doubt it would wipe the data, but not impossible of course.
check the drive contents in a hex editor (winhex or HexEd for example)
drag the scrollbar from top to bottom and let me know what you see, garbage looking thing or 00s

There is lot of numbers and letters.
Got this message on start
Partition 1 and partition 2 overlap by 160,314,632 sectors. If file contents / file system data structures in the overwritten partition are implausible or cause problems, then it's obvious why. Note that Partition 1 is not an existing partition that is actively referenced by a partition table. Merely traces of the start a potentially previously existing partition were found, e.g. a boot sector.
