winxp says file x is damaged and not readable executre chkdsk.
irfanview says: canno read file-header,unknown filesize, or file does not exist.
i was advised to run diskdigger.

I would restore from backup

Odds are the file is beyond repair and letting the app you linked to scan it probably won't make it any worse.

backup does not exist, thats why the idea to make an image first.
how do i make an image of my card? good data are backed up now.
data are images from the right camera of stereodatamaker(3dstereo)-software.
i will examine now data of both cards(left and right cam. it seems eighter card is not clean ir something is wrong for all data.

i cleaned card again, then backedup all data to a seperate sata-drive using win2k. yes, win2k can see my sata-drive now, sata-driver had to be installed. other than mentioned in an other thread.
will now try to recover corrupt data with diskdigger. any other good tool?thanks

diskdigger,pc inspector and imagerescue(lexar) did not have any effect on my corrupt files. i have now backedup the whole card in a folder goog files are deleted on the card. only corrupt ones left there. any more tools which could help?

FORMAT the card would be a good idea unless you're still hoping to get the corrupted files back.

1.i will buy a new identical card in order to work with the other one shooting 3dstereo. 2. will buy other card-types, also slower. class2, i am using class 6 and 133x.
3. i will change the shooting procedure, the settings. it was the first time when my cams were on for several hours, also lcd-screen. interesting is the fact that after changing the batteries(i didnt wait until the camera went off) images were safe on the right cam. i used eneloops and other hybrid-batteries. there are no better ones, except one-time use lithiums which a friend of mine is using.
4. i will get an image-tank. to save images regularly on location.

If you have problems with your memory card in 80% of all cases the controller of your card is damaged and no software or card reader can help. You must separate the memory chip and dump the raw data to recover your data.
