automatic usb harddisk mounting

Hey there,

I've been having some troubles with my usb harddisk. It automatically mounts, and Konqueror pops up a window, but it gives "Read-only file system" errors, even when it appears to be mounted read-write.

There is something very buggy about this and I'd like to get into contact with the people that are responsible for this auto-mounting or that have some knowledge about the process and that are supposed to know about this problem.

The problem sometimes just dissappears. Usually I can write to the filesystem a couple of times and then it suddenly switches into read-only mode. Or, I cannot write to it at all, to start with. Or, it starts read-only, and then it becomes read-write later.

Anyway,
is this a kernel issue? Should I contact kernel programmers? Is it a KDE issue? Where can I take this?

greetings,

Xen.

I think this is an issue with your drive. Please take a look at dmesg, when you're mounting:

Source code

 
1

sudo tail -f /var/log/messages

to see why it is being mounted read-only. It might be corrupted, as I had same problem with my flash drive. Backup data, reformat.

Hey kriko,

thanks for the reply. I had before looked into /var/log/messages, but did not find anything useful, but now with the tail this came up:

Source code

 
1

May  7 15:12:24 linux kernel: FAT: Filesystem panic (dev sda1)
May  7 15:12:24 linux kernel:     invalid access to FAT (entry 0xffffffff)
May  7 15:12:24 linux kernel:     File system has been set read-only

So I guess a reformat will do the trick.
Now I only need some way to back up all this data, which I would have needed anyway...

Just mount it in read-only:
#sudo mount -o ro /dev/xxx /mnt

What good will that do? It is already in effect read-only, so why would I need to mount it read-only?

Sorry, misunderstood.
