yes, it was connected while maemo was running, and in mass storage mode.

many thanks, I will try this.


Edit ---

many thanks for the help, again. my problem is not solved yet, but I keep trying.

so, when BackupMenu starts, the following messages are written:

"UDev started.
1
2
Error with: cp /lib/libacl.so.1 /tmp/disk/lib/ Code:1
cp: cannot stat '/lib/libacl.so.1': No such file or directory

3.

then it loads, and works fine. I press "w" to mass storage mode, then connect it to my ubuntu laptop. it sees (I mean I can see it in nautilus) the "ot a boot d" named phone (before using fsck and accidental deletion the phone name was "n900") with its 27 Gig storage, and the other 2 Gig partition (I assume the "/home" folder). so I ran testdisk and it does find partitions with the "Intel" partition table, but the listed partitions (after deeper search) are only the "ot a boot d", "Linux" (this is the 2 Gig partition), "Linux swap", and another "Linux" partition which also too small to be the lost partition. I'm a bit stucked now. my only idea is to run GParted on my ubuntu laptop to gain access to the n900's partitions...

(I don't know if I'm right, but I read that BackupMenu can do backup only from my rootFS and optFS, but not from my MyDocs folder which contains the .documents. and I don't know how to backup my lost partitions with it)

I ran Photorec too before installing BackupMenu, so it went through the process while maemo was running, and with Non-partitioned table (I connected it to my ubuntu laptop, so the recup folders were saved to the laptop - to the Desktop), and it does restored many lost files from the device, but not all of them I think, and I do no want to sort them one by one... (: (it is a nightmare...) and some of the .doc files can not be opened with OpenOffice (for example)...
