[Lilux-help] Corrupted files

Hello, I have a strange situation with some files (photos from digital camera): Although the timestamp of the file is not altered, the content of the file is not displayable anymore in any viewer. Looking at the content of the files (hexdump) told me that all of these files only consist of NULL bytes. There are 42 files corrupted, including one mpg file of 216 MB I tried to investigate further what could have happened to those files. Unfortunately, I have no idea when some event could have happened which might cause the file content to be nulled, but I am sure they have been intact only a couple of days before. I tried to investigate with the command debugreiserfs -D /dev/hdb3 . In the resulting file I found the filename and inodes of the corrupted files with entries like shown below. These entries do not differ from those I can find for uncorrupted files. ------------------------------------------------------------------------------- | 3|800 46096 0x0 SD (0), len 44, location 2980 entry count 65535, fsck need 0, format new| (NEW SD), mode drwxr-xr-x, size 10472, nlink 2, mtime 24/2007 21:09:07 blocks 21, uid 500 ------------------------------------------------------------------------------- | 4|800 46096 0x1 DIR (3), len 2824, location 156 entry count 89, fsck need 0, format old| ###: Name length Object key Hash Gen number 0: ".

Is there anybody out there who has some idea - why suddenly files can be corrupted this way - where I possibly can find more information about what happened (maybe logfiles to analyse, look for what???) - if these files might be recovered, and how Some possibly useful information: - Installed system is an OpenSuse 10.2 - Filesystem containing the corrupted files is Reiserfs - Timestamp, filename, filesize etc. of the ls command show the original data - No, there is no backup, otherwise I would not ask this question here - I regularly use the "suspend-to-disk" feature Any help would be greatly appreciated Thanks in advance, Jean-Jacques Mouris
