Mounting UFS HDD in Linux Mint

Blogger Repost: Monday 23 April 2018 - Last time used 27 April 2020


It has been a while since I decommisioned my FreeNAS server with-

  • 1 x 160GB HDD
  • 2 x 320GB HDD
  • 2 x 500GB HDD
  • 1 x 1.5TB HDD

The main purpose was to store/stream all my media files

  • Movies
  • Music
  • Images
  • CD ISO's
  • Important Documents
  • 1 x Shared Drive (1.5TB HDD) on the LAN
I have now found a use for those 2 x 320GB HDD but first I need to see what files are on these HDD's and tempoary transfer them elsewhere if necessary.
The problem is, the hard drive partitions are formatted using the UFS standard which Linux Mint cannot use. My computer with Linux Mint uses the EXT4 standard.
Thankfully there is a BASH work around, Linux will READ but cannot write to these drives. So here I used a HDD docking station.

IDE SATA Docking Station

To find out the label of an external hard drive, open up a terminal, and use the following command


Result (depends on what you already have connected)
sda 8:0 0 149.1G 0 disk
└─sda1 8:1 0 149.1G 0 part /
sdc 8:32 0 74.5G 0 disk
└─sdc1 8:33 0 74.5G 0 part
sr0 11:0 1 1024M 0 rom

from this I can see sdc is the HDD I need
(normally linux is installed on sda)
Now we to mount the drive using the following command

sudo mount -t ufs -o ro,ufstype=ufs2 /dev/sdc1 /mnt/

Now I can read/copy the files to another location before reformatting the drive with ext4 (or FAT32 for windows). Note pay special attention to the error that comes up on the monitor, this tells you the actual mount name you have to use, in this case it is sdc2. Last time I tried another HDD, it came up as sdc1, all depends on how many usb devices you have connected at the time.
