Multisession

#1 Post by HEMA »

In a cd there was some old photos, But while again loading some other photos in nero by mistake we have given multisession. The problem is all the old photos have been overwritten and we are not able to view that photos. Very rare photos which cannot be taken again. What to do. Please help me with this problem. The cd is not a rewritable one.

a quick google finds this
http://www.diskinternals.com/cd-dvd-recovery/
which says it works only on windows and has a free trial

I don't know how to do this on linux but I'm sure there is stuff out there.

Anyone else?

Had a quick look at the web site suggested by HairyWill and it seemed as if the free trial version was limited to recovering files of up to 64K. You have to pay for the full version to recover bigger files.

Another Windows solution, which does not have this limitation, is Isobuster. I am sure the free version is not meant to be used this way but it can be done with a little trickery. Not for the complete novice.

Have a look at my review of Isobuster and what I did when I lost my photos by looking here:

Are normal burnt CD's simply 'overwritten? Or, does the next session simply go alongside the first and somehow obliterate the first string character, like a deleted document on the hard drive?

This may or not be relevent and is just a suggestion but, try looking here:

Read of previous cdrom session

With multi-session cdrom, it is possible to delete files of previous session. Because the files are not really deleted, it is possible to recover them. To read files from the first session, run under Linux

mount /dev/cdrom /mnt/cdrom -t iso9660 -o session=0
Good luck!

Hi
All may not be lost quite yet. It sounds to me like the last session you burned on that CD didn’t link the other tracks together quite right. Nero is good at that. I don’t know how to retrieve your files with Linux but in Windows all you have to do is put the CD in your CD/DVD drive, then open up “My Computer
