Hi Forum,
according to cgsecurity http://www.cgsecurity.org/wiki/CDRW#Rec ... nked_CD-RW it is possible to recover data from quick-erased DVDs with a linux system.
So I downloaded latest AltLinux, booted it via USB Stick, mounted the session as described at above link.
But then I am completely stalled. Neither testdisk nor photorec have the mounted thingy in the disk list, so I cannot start recovery from there.
Can someone explain why the mount?
And how to go on after the mount?

Re: Recovery of fast-erased DVD-RW
Use "mount" to find the device and run "photorec /dev/sr0" (replace /dev/sr0 by the correct device).
Note that it doesn't work with all readers/writers

Thanks cgrenier for the hints!
I am sadly a noob with linux, and couldnt start the recovery of fast-erased DVD-RW. Here is what happens using latest ALTLinux:
* I found out that /dev/sr0 is my DVD-recorder via
* when I insert a "proper" DVD-RW (e.g. containing the sources of windows or ms office) then would work well, i.e. it shows the DVD-RW on the intial screen.
* when I insert one of the DVD-RWs I want to recover then does not work, it's output is:
which outputs: : in the mount command.
Any ideas how I can make the DVDs accessible to photorec?

Re: Recovery of fast-erased DVD-RW
Update:
I used an external USB DVD-ROM drive, and photorec now sees the disk when started via.
One disk I tried before was not successful, photorec finished recovery after 2 seconds, not sure why this happened. Will investigate later.
I just run a recovery of another DVD-RW disk and this seems to work nicely in pass 1.
