restoring and recovering .blend files

Support Technical Support
1

Hello.

My whole system crashed recently, I lost most of my work and all backups I copied got corrupted.

Blender shows thumbnails but it says that it cannot read the files - “format is not supported”

  1. Is there any method to brute-force files to open or… something?

I should have uncorrupted files on the mirrored RAID disk that is now not being used
2. Do you know any software that can recover deleted blend files?

append is the closest brute force i know of.

i backup to a flash drive and a mostly unplugged hdd, that way its isolated from disaster.

Since it seems to be a dead end I’ll just add that that is what I did.

The copies on the external disk were corrupted. Possibly microvibrations from the machine, because disk check revealed no bad sectors.
