I've just bought a 4TB external HD from Seagate and want to use it as an extension to my laptop (Linux Mint 18). However it's not mounting automatically. Having searched several forums, I can't find a solution to this. I've tried addressing the HD in the terminal, but

$ sudo parted -l
Model: ATA SAMSUNG MZNLN256 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type      File system     Flags
 1      1049kB  25,0GB  25,0GB  primary   ext4            boot
 2      25,0GB  256GB   231GB   extended
 5      25,0GB  246GB   221GB   logical   ext4
 6      246GB   256GB   10,1GB  logical   linux-swap(v1)

doesn't show the HD.

$ lsusb

After disconnecting, reconnecting and running:

$ dmesg | tail

$ sudo gnome-disks

just shows me the Model Seagate Expansion (0707) information, the Serial number and the Device /dev/sdc.

$ sudo mount /dev/sdc /media/disk4TB

tells me that it's not a valid block device.

Does anybody have an advice how to proceed in making it usable on Linux Mint18?

  • The Harddrive has a Partiontable ans is formated? – user192526 May 13 '17 at 15:50
  • @Bahamut I can't tell. I just unpacked it, pluged it in and I don't know how to address it. Also gparted wasn't helping – andschar May 13 '17 at 15:54
  • Your dmesg above doesn't look right. – Satō Katsura May 13 '17 at 15:56
  • Maybe a Problem with the Modul uas lsusb -v -d 0bc2:231a So we can write a quirk for your Harddrive. – user192526 May 13 '17 at 16:01
  • parted is showing you the partitions on sda. You need to tell it which disk to view: parted /dev/sdb – Michael Mol May 14 '17 at 2:52

If you are still having problems with this, try:

# modprobe uas

I had a similar issue with what looks like the same drive. You can add uas to /etc/modules to automatically load it:

# cat /etc/modules

# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

  • Note that you may need to wait a minute or two after doing this before the drive is recognized, so don't jump to immediate conclusions if you don't see it right away. – Kazark Aug 15 at 18:45
