USB stick permissions problem [solved]

Hi,

As a root, I mount my USB stick with: mount /dev/sda1 /mnt/stick

Prior to mounting the /mnt/stick directory has these permissions:

drwxrwxrwx 2 panu root

After connecting the stick and mounting, the permissions are:

drxwr-xr-x 7 root root

I can read it as a user but write only with root. After mounting the permissions can't be changed with chmod.

1. How could I write it as user?
2. Do I need to add something to fstab? currently I have nothing concerning the usb stick.

Thanks for any help!

You should add a line to fstab simillar to

/dev/sda1            /mnt/stick     vfat      rw,user,noauto           0    0 

Now you will be able to mount your usb stick AS USER using

mount /mnt/stick

if the above doesn't work try adding umask=0000 before 0  0.

Re: USB stick permissions problem [solved]

ok,

I appended the fstab as pressh suggested, and rebooted. Nothing changed: can still only mount as root and can only write as root.

then added the umask command so that the fstab line looks like this:

/dev/sda1  /mnt/stick  rw,user,noauto,umask=0000   0    0

Is this what you meant, Penguin? I rebooted, but still no change, and the permissions before and after the mounting are as I described in the first post.

Could it be something with groups? My user belongs to audio, storage, video and optical. Is there some other groups it should belong to?

and vfat is there also after the /mnt/stick bit of course..

Yes that's what he meant.

Don't think it can be a problem with groups, others than that you can perhaps have a mistype in the fstab line (e.g. wrote 'users' instead of 'user')

You actually mount using

mount /mnt/stick

????

because when you use

mount /dev/sda1 /mnt/stick

/etc/fstab will not be used, and so you'll not be able to mount as user
