I have a 6 to 1 media card reader and using Ubuntu. I'm not able to read the compact flash, will read the SD/MMC card. I'm able to read the card using WindowsXP and Vista.

I open the computer and see the Compact Flash Drive icon I click on it and get error "Unable to mount media." I can install a SD card with no problem reading. I'm very new to Ubuntu and Linux, I have search with no luck.

I'm getting the same thing with my usb hard desk ??

i never had this problem before ??

I'm using the ubuntu 7.04

Ok i also get "You are not privileged to mount this volume."
what is that ??
how do i fix it ?

thanks every one

screener: I use SuSE with KDE but maybe there is an option similar on the Gnome desktop. If you right click on the device icon on the desktop and select properties, see if there is a mounting tab with an option "Mount as user".

Then, when the hal/udev system detects the card it should create a device node with the desktop user as the owner of the device.

IggyGal: Since an Icon comes up, is sounds like the device is being detected. I think you may want to monitor the kernel messages before inserting the device. Open up a terminal program and run "sudo tail -f /var/log/messages". Then insert the device and moniter the messages that come up. Do all flash disks do this? I wonder if the filesystem on the disk might be corrupt.

You could try mounting it manually. Notice the device node that was printed when monitoring /var/log/messages. It might be something like /dev/sdc1. Then use the mount command as root to try mounting it temporarily on /mnt.

sudo mount -t vfat /dev/sdc1 /mnt -o defaults,umask=000

See if it mounts or if there are any error messages. If there is an error message about bad superblock ..., you could try checking the filesystem on the disk:
sudo /sbin/fsck.vfat /dev/sdc1.

Keep in mind that I made up the device in these examples. It may be /dev/sdb1 on your system.

I have never heard of a 6 in 1 Media Card Reader working in Linux. Who manufacturers this? How is it attached to the Motherboard? You may need to manually mount the drive:

i.e sudo mount /dev/xxxx /xxxx

The best thing may be too look up the manufacturer and see if they have specific drivers for this application.

I was actually trying to sort out my Sandisk SDDR73 cardreader this morning. Card reader showed up as 2 drives when I looked in /places/computer/ , but it wouldn't mount due to not being able to read the CF card. Found the info I needed on the following site http://www.linuxjournal.com/article/6687 and tried a reformat on my CF card through my Canon camera. Tried with a new photo and it worked fine. Was wondering about the 2 devices showing when I first saw them, but the webpage info from the link above stated, that Ubuntu recognizes each card slot in the card reader as a separate device. For mine it defaulted to the CF card, but your reader might be different.

These have worked for some time in Linux. Each type of card slot is treated as a separate drive. There used to some issues with multislot readers but these have been fixed in the kernel drivers. These readers are USB and the internal ones connect two pin headers on the mother board. You can see a variety of these devices at pcclub.com, search for "card reader".

Interesting. Never knew that. Thanks!

Thanks everyone. After about three hours of searching and reading I was able to read card. Actually I had to format card with the camera. Not sure why but looks like it working. Again thanks
