I have a hard drive with Linux Mint installed that I recently rescued from a dying computer and have been using a USB to SATA adapter that comes with an external power adapter to try to get some data off that hard drive onto my netbook which uses Ubuntu 12.04.

Unfortunately the hard drive won't mount, and I can't figure out how to access the data in it.

There doesn't seem to be anything wrong with the hard drive itself. I actually tried installing it on a third computer (without the SATA/USB adapter - just connected the sata cables to it) and it boots up and runs fine. I checked for signs of disk errors and ran a few diagnostic tests and there are no problems there.

Any ideas?

Here is the output from dmesg:

and fdisk -l

fdisk: unable to seek on /dev/sdb: Invalid argument

in gparted, the /dev/sdb entry shows up as "unallocated".

for lsusb:

Edit add: Here is the product I am using: http://mail.ultraproducts.com/product_details.php?cPath=104&pPath=669&productID=669

Second edit: Tried sudo gdisk -l /dev/sdb here is what I get:

  • Never seen the overlapping thing before... did you try o mount it? – Scott Goodgame Aug 30 '14 at 0:54
  • Not yet - just wanted to first make sense of the error before trying anything else. It's a bit mystifying but I've been trying to figure out if it might be something being messed up with the disk. – user1790399 Aug 30 '14 at 13:20

It might be using GPT rather than MBR. You can mount it with..

You can try gdisk instead

sudo apt-get install gdisk
sudo gdisk -l /dev/sdb
sudo mount /dev/sdbX /mnt    #Where X is the partition you want to mount.

  • Thanks! I had to use sudo apparently to run gdisk, but I have updated the question to reflect this output. I'm still a bit confused by the output, but it seems like MBR is being used after all? – user1790399 Aug 30 '14 at 0:37

I'm an Arch Linux user and I had the same problem.

The solution was install ntfs-3g and reboot my laptop

extra/ntfs-3g 2017.3.23-1 [installed]
    NTFS filesystem driver and utilities

I can see my device now:

lsusb && sudo fdisk -l && lsblk && dmesg | tail -n 20

udevadm monitor
