I put a 64GB Kingston USB key in one of the USB ports on the Pi.

It has been recognized and mounted automatically and I am able to write files, but why, in the MEDIA directory, has KINGSTON has been split between KINGSTON and KINGSTON_, one with 16 GB and the other 48 GB?

When the first is full what will happen, as my code mentions only" /media/KINGSTON"?

  • If you could run mount and sudo fdisk -l and post the output to pastebin.net that would be useful.

Probably it is due to filesystem type limitation when automounted. If the key is empty so wiping all the data inside is not a problem (thanks for the comment RPi Awesomeness), you can create an ext4 filesystem with

sudo mkfs.ext4 /dev/sdNN

where NN is the device name. You must first dismount the already mounted drives with either:

umount /dev/sdNN


umount /directory mount point

for each one.

    This is a very useful answer, but just as a heads-up to people who aren't as computer/Linux-savy, formatting (making a filesystem as suggested here) will wipe your data. Just a heads up, if you're doing this, make sure to back up any data you don't want to lose. Great job on the answer. Commented Apr 4, 2014 at 13:20
  • Also it will be /dev/sdNN. (/dev/hdNN is for legacy IDE drivers only since the kernel moved to the (S)ATA modules by default.)
