Wrong filename case when inserting a camera memory card.

robin_listas · May 19, 2011, 8:03pm

In short: the files in 11.2 of the memory card from my camera were lower
case, and in 11.4 they are upper case. Thus, F-spot uploads all the photos
again, and I get two copies of each, one low case (old), another upper case
(new), without the comments or rotations that I had made.

How can I make the system automount it again in lower case?

I knew the proper options to do this manually in fstab, but not via udev or
whatever it uses.

Mounted as:

> minas-tirith:~ # mount | grep sdb
> /dev/sdb1 on /media/AEA9-05F6 type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0022,dmask=0077,codepage=cp437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks)

Can I somehow force it to be mounted lowercase as before, or do I have to
accept this change?

I did some googling, this may be an issue with vfat.

Some people suggest mounting with the following options


shortname=lower
posix=1

Good luck,
Hiatt

I think this is what Carlos already knows and this does not help for udev.
The point is how to tell udev (which is used by gnome and kde for that
desktop environment automount feature or however it is called) to do the
same. I did not find out so far. With fstab it is obviously no problem, with
udev rules I seem also to be completely unable to find out how to do the
same.

Yes, indeed, vfat mount has options to convert all files to uppercase when
mounting in linux. I know that.

It is automounted by Gnome, thus the options are beyond my reach.

I may have to indeed, mount it manually always to bypass this bug.

No, this is something that the good folks at openSUSE/Gnome have done. They
default to mount vfat with the options that convert all names to upper
case, while on previous version they did not - thus breaking things.

Sorry, I guess I’m not much help here.

It seems it’s hardcoded in DeviceKit and the developers get flamed here:

Rant: Arrogant Developers - Kirsle.net

I’m fortunately I didn’t hit this because I download directly from camera using USB from digikam rather than deal with flash cards.

I’m guessing that it is 11.2 which was wrong and converted to lowercase. I
have to check two things later and I will comment on that.

Yes, it matches my checks so far.

In 11.2 the camera is detected, but does not work. In 11.4 I haven’t tested
it yet.

Yes, 11.2 mounts the card like this:


>
> /dev/sde1 on /media/AEA9-05F6 type vfat (rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=100,shortname=lower,dmask=0077,utf8=1,flush)
>

The trick is the “shortname=lower” option. This happens because of this
setting in gconf:

/system/storage/default_options/vfat/mount_options
shortname=lower,flush,utf8,uid=

And indeed, looking at the hexadecimal dump of the card, the filenames
(short) are stored in uppercase. Thus the correct display is uppercase. The
problem is that it is a different default than in 11.2, and there is no way
to change the default - except mounting manually.

11.4 mounts differently:

>

And all the /system/storage/ keys in gconf have disappeared, we can not
configure defaults. Now it uses “shortname=mixed”, hardcoded.

So, yes, there has been a change, and the user has been denied control.

Yes, 11.4 can work with the camera. But the connector is small and very
easy to disconnect, just moving the camera unplugs it in mid-transaction.
Dangerous.

read the directions, i’m sure it is in your camera user manual:

“Do not move the camera while connected to another device.”

Ha, ha. Look how I laugh :-}

I did not move the camera. I just used the laptop’s touchpad, the hand
passed near the cable… that was enough.

that is really kinda strange…is it a proprietary cable on one end and
usb on the other?

i ask because my current camera uses a standard USB cable, and though
the part that plugs into the camera is very small, it is also quite snug
and i’ve never had it just fall out…

maybe put a rubber band around the camera to trap the cord in a place
where it can’t fall out…

Yep.

The “proprietary end” has an engrossment with some electronics and
red/green LED. The same cable is used for charging. The engrossment in the
cable impedes the plug from fully entering the camera socket.

It doesn’t fall out, it just moves a bit and the usb connection fails. The
battery connection may still work, though.

Or not use the cable with the laptop, only with the desktop.

By the way, I think I lost some photos, or I can’t find them again. I don’t
see a missing number in the filenames, but I can’t find two photos I made
of an interesting antena. Weird. Yesterday afternoon I saw them. During the
night they disappeared. With all the testing I deleted the directories
several times in both computers, but never in the camera. But those two or
three photos are somehow lost.

Must be a secret black operations antenna, so “they” wiped the proofs. :-p

Oops! What from the ground, afar, looked to be antennas, when zoomed in
were really power line isolators. So I did not recognize the two photos for
what they were, the power line itself I could not see in the bright sun and
several hundred meters below. Curious!

Mystery solved.

i think would contact the maker of that camera and (nicely) complain
about the design (which is the apparent problem)…i mean either your
cable is not produced to design, or the design is faulty…in either
case the manufacturer should be happy to receive your “bug report” and
either send you a correctly produced cable, or maybe they have already
changed the design and they will send a good one to you…

if they won’t do either you can let’em know which camera manufacturer
you will not be purchasing from in the future…

[am happy you solved the Black Ops Antenna mystery!]
