What settings to use to increase recovery success?

#1 Post by amskuay » 20 Jan 2015, 08:02

Thanks for this awesome program. I have been able to recover jpg files from an SD card which had been formatted. Thankyou for all the hard work you've put in!

Unfortunately, I had a little accident yesterday - I was trying to fix a thumbdrive with disk part and used the format recommended override function. Unfortunately, I specified the wrong volume and it targeted my 2TB secondary HDD. I realised 1% in and quickly stopped the procedure. When I then checked the secondary HDD, I saw that it was RAW. The bad news does not stop there. When tried to access the drive through Windows explorer, it said I needed to format the drive in order to access it. I thought that format doesn't really delete the data so I pressed ok to format. The process only took 2 seconds. Obviously the secondary HDD is now empty, but at least I can access it.

So I have used photorec to try and recover the data - it is all photos. But nothing has turned up. I had 181GB worth of photos there and it cannot seem to recover any of it. What settings would you recommend to increase my chance of recovery success? Thanks so much... My wife is close to kicking me out!

Run TestDisk, Advanced, select the partition, choose Boot, RebuildBS, List, if you see your files, choose Write and confirm, Quit
Please post the testdisk.log content if it doesn't work.

TestDisk exited normally.

I had previously tried aggressive search also, but it was still running after 36hrs, so decided to stop.

Try PhotoRec, in Options, enable the expert mode, start a recovery, use a blocksize of 512, use the default settings otherwise. Do you recover your pictures this way ?

I've tried that too and it didn't really do much. I Don't understand where it could have all gone.
