Hello,
I have an external HDD and when I plugged it to my system then it is detected, but not mounted:

Code:

$ lsusb
Bus 002 Device 037: ID 125f:a15a A-DATA Technology Co., Ltd. DashDrive Durable HD710 portable HDD various size

And:

Code:

$ sudo fdisk -l

Partition 1 does not start on physical sector boundary.
Partition 2 does not start on physical sector boundary.

And:

Code:

$ dmesg | tail -n 17

Have you tried removing from the ADATA enclosure and connecting directly to SATA interface?

You could try to connect it directly with SATA as labtech suggested.

If that is not possible or after connecting with SATA you can try to image the drive with dd_rescue:

Code:

dd_recue -d -n /dev/sdb /home/[yourusername]/imagefile.dd /home/username/imagefile.log

In case you have some bad sectors while imaging you can try to fill the gaps with

Code:

dd_recue -R /dev/sdb /home/[yourusername]/imagefile.dd /home/username/imagefile.log

Be aware you need 500GB free space in /home/[yourusername]/!
