[SOLVED] udev pen drive filename length

gosala · 10-06-2011, 10:14 AM

Hi,

I have a problem with mounting pen drive using udev. I am working in an arm development platform and installed udev successfully. My udev rules are as follow.
BUS=="usb", ID=="1-1", KERNEL=="sd?1", NAME="pen1"
What I want here is to assign node "pen1" whenever a pen is mounted to port "1-1". udev works fine but when I mount using "mount /dev/pen1 /mnt" and access the content, the filenames appear corrupted and show only 8 bits.
eg: myfilename.mp3 is replaced with myfile~e.mp3

what should I do?

What file system is your pen drive using?
jdk

Hi jdk,

It is vfat.

Maybe that's causing the file mangling that you observe. Is there any reason to use vfat rather than another file system?

Hi jdk,

apparently I can't use other fs. anyway I used udev-110 which is a quite older version. Can't it be a problem?

Yeah I noticed that and wondered why. It's usually not necessary to write udev rules to mount an external drive. The older version could be the problem. I'm using version 172-1. Are you using a very old version of Ubuntu? You ought to be able to install a more recent version and see if that fixes the problem. Updating udev may involve updating a lot of its dependencies.
What makes you think you can't use another fs on the pen drive?

Hi jdk,

It was a problem with mount command.After adding -vfat argument in to my mount command problem solved.so thank you very much for your advices. I learnt a lot from you.
