Kindle and Read-only file system

Some times ago i moved on 64 bit system and my first problem with new system was situation when i couldn't copy any files to my Amazon Kindle 5. Every time when i tried to delete some file from Kindle i got following error:
[Errno 30] Read-only file system
Here is the solution how to fix it. First of all need to determine your device. Execute mount command for this, and you must have something like this:
/dev/sdc1 on /media/alex/Kindle type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2)
 After determination, just execute:
 sudo fsck.vfat -r /dev/sdc1
Unmount and remove and plug again the USB cable of your Kindle device, and after this simple manipulations you'll  be able to copy any files to your Kindle.
