hi, i've installed mandriva 2006, and i cannot access my pendrive (scandisk).
following a reply in another thread (i am a beginer in linux) i ran dmesg and got

Initializing USB Mass Storage driver...

following the same reply, i tried

mount /dev/sda0

and i got

mount: it was not possivel to find /dev/sda0 in /etc/fstab or /etc/mtab

so what should i do to read my pendrive?

thanks!

Sometimes you need to wait for up to 20 seconds for Sandisk sb drives to work. It should automount on it's own. If not, the drive should be accessable through /dev/sda1 (not /dev/sda0 - doesn't exist). It's also possible that your drive has a newer device ID than the usb-storage driver supports.

Try plugging it in and waiting a few seconds to see if an icon pops up on the desktop. If not, type "mount" in a terminal window to see if it has at least mounted it. If it isn't mounted, try "mkdir /mnt/usb ; mount /dev/sda1 /mnt/usb" (as root). If that doesn't work, type "lsusb" and "dmesg" again and post both results.

i waited, didnt work. so i tried the commands, got

mount: it was not possible to find /dev/sda1/mnt/usb in /etc/fstab or /etc/mtab

lsusb returned

and dmesg (i am posting what i think is relevant out of the hundred or so lines)

The space needs to be between /dev/sda1 and /mnt/usb. /dev/sda1 is what you want to mount and /mnt/usb is where you want to mount it to.

it worked, thanks!!!!

sorry, but now i can see the pen drive (for instance with
kdiskfree) and its contents, but when i try to copy files in it, it says "access denied".

i've noticed that the files in the pen drive are "labeled" with

username: root
group: root

help!!

in fact, when i try to unmount from kdiskfree, it says

unmount /dev/sda1

unmount: /dev/sda1 is not in the fstab (and you are not root)

You should be able to write to the drive as root.

yes, but i would like to be able to read it with the tools in
kde, and logged as a "normal" user. is there a simple way to do this?

thanks!

First, let's step back to beginner mode (Mandriva is geared for this). Start the Mandriva Control Center (Start menu->System->Configuration->Configure your computer). It will require root password to run. Once in, select System->Enable or Disable the System Services. Scroll down and make sure that haldaemon exists and is running.

If it doesn't exist, click cancel, then go to Software Management->Install Software. Search for hal (use the seach window). Select it and install it. It should automatically start. If not, procede to next step.

If it does exist, but isn't running, make sure boot is checked, and click on start for that service.

That should take care of it being mounted automatically. If not, let me know.
Also, which desktop are you running? (KDE or Gnome)

>Scroll down and make sure that haldaemon exists and is running.

yes, it exists, and it is running, and is starts with boot.
but the pen drive does not mount automatically.
I am using KDE 3.4.

I'm not sure why your drive isn't automounting. Here is what I get when I plug in my sandisk 128M stick:

Check to see if kded is running.

yes, kded is running.

what commands do i use to copy files from /home/username to the drive as root?
can i use kdiskfree as root?

thanks!
