I have tried to mount an external USB 3.0 hdd on my debian virtual machine (I'm using VirtualBox). I have tried to mount it using mount /dev/sdb1/ /media/vol1/ but I get the following error:

mount: can't find /dev/sdb1 in /etc/fstab of /etc/mtab

I have tried to use fdisk -l, the error I get is the following:

    WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdb: 1000.2 GB, 1000170586112 bytes

This is the result of parted -l:

How can I mount the hdd and read its content?

Please include the command you ran which gives the error. The output you show and the error you quote are from fdisk which has nothing to do with mounting. – terdon Apr 26 '14 at 10:21
Thank you for the suggestion. I improved my question, I hope that now it il clearer. – giovi321 Apr 27 '14 at 16:26
Please follow the suggestion in your error message. Edit your question and add the output of sudo parted -l. Don't take a screenshot, just copy paste it into your question using the formatting tools available. Also, check man mount. The format of the mount command is mount partition mount_point, so you would need something like mount /dev/sdb1 /media/disk. – terdon Apr 27 '14 at 16:33
Thank you for the suggestions. I did use mount correctly, it was a typo in the question. I also put the results of the commands formatted correctly instead of the previous picture. – giovi321 Apr 28 '14 at 19:07
I think the reason for the error message is quite simple: you need to drop the trailing slash from /dev/sdb1/ and just use /dev/sdb1. With the trailing slash mount will treat /dev/sdb1 as a directory and search for a device to mount there in /etc/fstab. – Graeme May 1 '14 at 18:32
