Can't find it in /media or /mnt.

What I want:

  • live distro so I have guarantee it won't break and will boot/work every single time
  • have access to directory on that USB drive for storage purposes, ie. use in typical pen drive fashion

What I don't want:

  • persistent install
  • use, as it makes much harder/impossible to access data from other machines
  • partition the drive as it makes backups/cloning harder and isn't elegant

I tried to be clever, reinserted the drive after boot, but then can't even run the terminal.

I'm using Linux Mint 13 XFCE

To find your USB drive, first issue:


then you will see something like:


where as /dev/sdxy is your usb drive which x={a,b,c or d} and y={1,2,3,...}

now issue:

mount -l|grep /dev/sdxy

it will show (something like):

/dev/sdxy on /PATH/TO/USB/MOUNT/PLACE type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,quiet,errors=remount-ro) [USB_DRIVE_LALBEL]

I hope this will be quite helpful.

You can see where the device is mounted with Disk Utility, it use to be mounted in:


You can't unmount the device but you can remount it with write permission:

sudo mount -o remount,rw /lib/live/mount/medium

Then maybe you wont be able to drag & drop files in directory but you can do it with terminal:

mv file.txt /lib/live/mount/medium

This works for me in every live USB Linux I've used. Regards!

Yes you can't find it in /media or /mnt, standard casper + AUFS mount the USB drive that holds filesystem.squashfs to /cdrom or /cdrom0, that's where you're looking for the USB key partition.

For the rest, just open some file manager, maybe Thunar, you'd see them on the left panel.

And if you re-plugin the key, it would ruin the live system.

Almost, is mounted there but read only, I need to write to files. –  null Nov 5 '12 at 19:23
mount -o remount,rw /cdrom –  Jim Paris Nov 5 '12 at 21:55
Remounting works for me, how come this isn't accepted as an answer? –  Ehtesh Choudhury Mar 8 '13 at 16:11

Ubuntu mounts it rw at /isodevice

Hmm, Mint which is based on Ubuntu does not. I could use Ubuntu, but prefer Mint and in general want bit less distro specific solution. –  null Nov 5 '12 at 19:48
I know you're using mint, which is why I specified that this was for Ubuntu, in case anyone else came across this question and was wondering. But anyway, this is most certainly a distro-specific thing, because they're all different. –  Jim Paris Nov 5 '12 at 21:55

These aren't the 'right way', but might work for you:

  • If I understand what you want correctly (esp. that you do not want a persistent install), you could just partition the USB drive, and make a data partition.

  • You can boot with the 'toram' kernel parameter - then you can unplug and re-plug safely. Where you specify that depends on the bootloader being used, but you can try it (non-persistently) at boot time, then figure out how to make it permanent (if you're using syslinux, it will be in syslinux.cfg).

Both kinda 'kludges', but might do the trick ...
