New external sd card reader mounting problem

[dr-kart]

Ubuntu 12.10x64 can not mount external usb card reader with sd card, FAT32 formatted. Win7 opens and operates it with no problem at all.

Gparted CAN see device but says about mounting problem. See pics.





The same symptoms in 12.04.1. Help.

That's strange...
Could you post the output of:

dpkg -l | grep 'dosfstools\|mtools'

[dr-kart]

dpkg -l | grep 'dosfstools\|mtools'

ii  dosfstools                                3.0.13-1                                  amd64        utilities for making and checking MS-DOS FAT filesystems

Connect your sdcard to your computer and post the output of:

tail -n 20 /var/log/syslog

If this sdcard is empty, go to gparted and create a new partitiontable (msdos) and a new fat32 partition.

[dr-kart]

I did that before. Gparted created fat32 partition. And I was able to write on flash. But when I unmount and mount device I get same error. While no errors on Win.

Edit: after gparted formated (fat32) sd card I put some files on it. No error messages on ubuntu. But then I checked it on Win and saw NO FILES on it! So data writing was failed on ubuntu.

The problem here is not the partition, rather than the partition table itself.
Have you tried to create a new partition table?

...Have you tried to create a new partition table?

Just did it with creatian new partition table (msdos type) first. All the same. Creation successful.After unmount and mount again I get same:

Well, there's still this line:

Windows tends to ignore hardware errors to a certain point. Do you have a second sdcard you could plug in to your card reader just to see if this behaviour can be reproduced?
