View Full Version : [ubuntu] Ubuntu can't find partition

August 4th, 2010, 07:27 PM
I plugged my usb HDD with 3 partitions on it, but Ubuntu sees only one... how to show other ones?

What happens if you type

"sudo fdisk -l"?

Partition table entries are not in disk order

(it's not the whole log, just the one 'bout the usb hdd in question)

How to mount other partitions...?

Well, you can manually mount them using the mount command (note that due to the fat32 formatting, you will need to do some stuff to get th epermissions right; they cannot be changed except at time of mounting).

All I can remember about mounting fat32 is that you use the "-t vfat" switch.

Automounting is handled in /etc/fstab for internal devices, but I don't know whether you can do that safely with a device that may or may not be plugged in.

What's weird is that it discovers one of the partitions.. why it can't mount others?

August 4th, 2010, 08:29 PM
That is strange, because normally all partitions will automatically mount when you plug a USB device in...even when you reboot and leave the device plugged in.

Which partition is it that mounts? That way, it will be easier to figure out what the problem is with the rest of them.

It shows one partition (named 250 GB something something, but it's only 10.1 GB large). I know wich one it is, but I don't know how to write it...

I am not sure what version of Ubuntu you are using but "disk utility" is installed by default in 10.04 and, I believe, available for 9.10.

If you are on 10.04 it will be found at System>Administration>Disk Utility.

It is a pretty handy little bugger and should pick up the partitions if fsdisk is and then you just need to click on the partition and then on "mount partition".
