Hi.
First i must say that i am totally newbie in recovery files/disks matter.

Now, i don't think i can explain what happened to my 3 usb external disks and my Mac OS X El Capitan disk.
All i know is my mac froze and i rebooted the Mac (pressing the button).
Now, i couldn't enter in El Capitan (for what i saw i lost some important files of the system).
Then i Installed a new partition and a new El Capitan, without deleting the first El Capitan.
After i installed i saw that my external disks lost some folders and lots os files mysteriously.

I used already Data Rescue 4 ; blacklisted_site Mac Data Recovery ; EaseUS Data Recovery ; DiskWarrior and right now i am using iSkysoft Data Recovery.

All of them just show me known files. Well, i would like to have more than that since my disks are, it seems, physically fine.

I would like to know if i can retrieve the lost folders and files to their initial places? I need some *.CPR files and none of this programs i used can find them (Steinberg Cubase files).

What do you recommend? TestDisk or PhotoRec ? LiveCD or can i work right in El Capitan 2 ?

PhotoRec can recover .cpr files, they are part of the RIFF file family. They are recovered by default.

I'm running now the photorec with riff family selected.
All is finding is wavs... Will it find *.cpr eventualy?
