usb fstab entry won't mount r/w

Hey all,

I have a usb drive that im trying to mount in fstab and it won't let me mount it for r/w, only r/o. This is very frustrating. Here is the line:

/dev/sda1 /mnt/usb auto noauto,user,rw 0 0

Just a note that if I put kudzu in the line at all it erases everything. I'm fresh out of ideas here.

Kind regards,

what's the file system on your usb drive? If it's ntfs, you probably won't be able to mount it r/w.

I'm not sure,

I think its vfat, since I was able to mount it earlier as root using mount /dev/sda1 /mnt/usb
and I copied some files on it. The machine got rebooted by accident when copying those files, do you think I maybe corrupted the fs ?

you can check what the filessystem is by
fdisk -l
(as root).

I'm not sure about corruption. Maybe that can happen. If you can mount it read only, you'll be able to save the files on it, if you have to reformat it - better than nothig.

Man, I have the same problem, and my USB External HD have two partitions, one with FAT32 and another with Ext3, so is not NTFS problem...

What I have found is:

When I log in with "root" user, the r/w mode is functional, but when I log with any other account, the USB HD is read only.

I haven't found how to handle this, but I have tried all things what comes to my head:

* Changing the fstab to allow all users r/w
* Assign GUID of the user
* Delete it from fstab and let Linux detect it again
* Creating a new partition in External HD!!

Nothing of above have solve the problem.

Any help will be higly appreciated.

Regards!!
