View old internal hard drive

[crazygk02]

I re0installed a 3tb Toshiba internal hard drive that I had taken out of an old Linux system and set aside.
I now have a new installation and I am trying to be able to view the content of the internal drive.
I am only able to see and mount the 548 mb boot system (Sda3). There is another partition on the drive that is 700 gigs and I would like to be able to see that partition but I don't see a way to mount that particular drive (Sda1).
I am currently booting off of Linux mint in Sdb1.
Sdb3 is the old boot record that I can see currently. How can I access Sda1?

NAME FSTYPE LABEL UUID MOUNTPOINT

├─sda1
├─sda2
└─sda3 ntfs 054C3286306D7A41 /media/tester/054C32863

Can you see the partition with blkid or gparted?
You will need to get the UUID.
If you can, this worked for me in a similar situation:
Open a terminal to get the UUID:

blkid

Make a mount point:

sudo mkdir /media/<something>

Then edit /etc/fstab with elevated privileges (I like xed)

gksudo xed /etc/fstab

At the bottom Add 2 lines(obviously using the appropriate UUID):
# Mount <something> Partition /dev/sda1
UUID=ea9f1b41-fb8f-494b-b049-6d9554d6e0a9 /media/<something> auto defaults 0 2

Save and reboot

You will probably have to change ownership to if you want to do more that read only:

Open a terminal:

sudo chown -R <username>:<username> /media/<something>


Hope that helps.
