not authorized to access external hard drive
 

I am running Raspberry Pi, and when I plug in my Toshiba external hard drive, and I try to access the contents of it, it gives off an error message saying that i am "Not authorized". I can't mount it.

Is the drive password protected?
Is the user part of disk, plugdev & backup group? Check /etc/group

no, it's not.
not sure what you mean - i ran a cat, and for the specific user logged in: 1003 is the last value.

Do you have hdd password set in bios of Toshiba?

The user name should be next to those entries

no, i don't. and the usernames do show up.

Use your editor to add

and just exactly how did you mount the drive and what flavor of linux are you running on your Pi?

what am i adding? that line that is selected?

You are adding username to the group.
See my example I have 2 users

Also as lleb requested what Distro are you using?

Try this if you have the sudo command enabled if not then just become root and then try this
Note replace the sdxx with the device you are mounting it can be sdb or sdb1



then
then
Once you have done running these commands open up your file browser and navigate to /home/shares/public and all your files should be there

To find what name your system is giving to you device drive and type in terminal, as root "mount" it will display all the devices pluged in your system
Also if you type fdisk -l also will show you the list of drives and partitions in your system.

Good luck to you!
