Noth ing against any tool that gets the job done, I still have to use Windows for my laptop when I want wireless access cos the PCMCIA card I was given will not work in Linux, not even with ndiswrapper so there you go.
I do hope you have now formatted the card and no longer have the initial problem

hold on your horses (like they said)

I got them back. to my shame, I found in the package of the media reader a program for Windows called HAMA photorescue. to my shame because I would have preferd use Linux but thos was too important to me to pass a solution. so I recover my photos even if I still cannot access the folder from a prompt or a filebrowser

thanks for everybody's help

hello all,

I tryed all that was suggested while it was suggested, it might be that the file system is behond recovery as even if I edit the card.img suggested by Nelz using khexedit suggested by towy71, I cannot find the directory with the corrupted name
the only error messages that I get while accessing the card after mounting /dev/sda1 is that the file does not exist, escaping the ? does not work (as I indicate in a previous reply)

I am very gratful for the help and suggestion, it hopened some other possibilities.

but... is there a software that can edit the filesystem (not the files) ? ))

thanks

A ? character won't stop you accessing the directory, just escape it. You seem to assume that the filesystem corruption is limited to changing the name of one directory. It seems moree likely that the filesystem itself is corrupted, otherwise "cp -av /mnt/card ~/W would show thew files being copied.

You have been ofered several suggestions that may help. why not try these before asking for more? EWven if they fail, the error messages may give further clues as to the cause of the problem.

But if you use dd to take a copy of the entire card to a file (dd if=/dev/whatever_the_card_is of=card.img) you could then edit that file, then mount the file to access the pictures...

good one the khexedit, but infortunatly, it cannot edit the filesystem, only the files, so I still cannot rename my directory.

thanks anyway towy71

sorry, I muyst have explain too much and badly.

I am looking for a software that can access the filename at a hexadecimal level so that I can rename the directory that is missnamed. all the rest is done, I can mount, ready the good part of the card, I can use gphoto2 for the part of the card that is not corrupted...... there is one folder in the card that cannot be enter by anymean, only list using ls, but has it contain ? signe, the shell try to expand it. and escaping with \ doesnot work either. I know that mc can ready files in hexa and it is possible with some software to modify a file in hexadecimal but here it is the filename that needs to be modify

I have problem to explain the problem clearly as english is not my first language

here is the result of ls
localhost:~# ls /mnt/loop
d?i? ecim

localhost:~# ls -la /mnt/loop
: No such file or directory
total 22
drwxr--r-- 4 root root 16384 May 1 09:54 .
drwxr-xr-x 7 root root 4096 May 1 13:22 ..
drwxr--r-- 3 root root 2048 Apr 28 21:35 ecim

thanks for the help

I'm not sure of corruption, I have some cheap dvd drives.....never again......but sometimes, if I take one disk out and put another on in it does what this person described, it sees the files (so mounts the drives) but all the names are in ????, I have tried umount and mount manually but nothing works, I normally have to just leave it and come back later, in which it starts to work again....the machines I have are mdk 10.

Like Nelz (in Warrington, really?) I suspect that there's some major corruption going on there. I've never seen a Canon card corrupted. I wonder if it was reformated off the camera, so to speak?

Still dd will at least preserve anything that is there.

If the camera cannot read it, the card's filesystem would appear to be corrupted.

I wouldn't try to fix it on the card, one slip and you make everything worse. If you cannot copy everything off with the cp command I gave, which would at least give you access to the pictures even if the names were screwed, try using dd to make a backup of the card first.

Code:

dd if=/dev/sda1 of=card.img

Then you can mount the image with

Code:

mount -o loop card.img /mount/point

and experiment with that.

hello nelz,

it is not a problem of monting the system, as I can see correctly the other folders, the problem is that I bought the camera while traveling in peru and that canon dump his olds camera there, so the firmware of the camera needed to b e change

but in the midtime, I have all the birthday of my son on it.

the camera itself cannot reread the photos, but shows that the media card is full.

Windows can see only the config folder, only linux can see the corrupted folder but it see it has a file of size 0byte and with illegal caracters in the name,

so I am trying to rewrite the names directly on the card so that I can access it using bash or other.

gphoto2 can see the photos that where taken after the folder was corrupted as the camera recreated a new folder with the correct name

Can you access any files on the camera? Does

Code:

cp -a /mnt/cf ~/

copy the files? change /mnt/cf to the mount point of your card reader.

If not, I suspect that either the filesystem is corrupt or you are trying to mount it with the wrong filesystem module (e.g. msdos instead of vfat).

The first thing I'd do is copy the files using gphoto (or camera:/ in Konq's location bar) to make sure they are safe. Then try different options for mounting the card. If all else fails, and you have copied the photos, try reformatting the card in the camera. It may simply have become corrupted.

try all of this (should have tell it before) konqueror and nautilus do not see the directory, bash see it but when trying to do it I get "cannot stat no such file or directory"

escaping the ? does not work ether. I beleive that only at hexadecimal level will I be able to fix this but any other solution very much welcome
