Is my HDD dead?

[hack3rcon]

Hello.
I have an external A-DATA HDD and when I plugged it to my system then it can't be mounted.

Code:

$ lsusb
Bus 004 Device 002: ID 8087:8000 Intel Corp.
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 8087:8008 Intel Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 007: ID 125f:a15a A-DATA Technology Co., Ltd.


When I use "testdisk" for recover it then :

Code:

TestDisk 6.14, Data Recovery Utility, July 2013
Christophe GRENIER <grenier@cgsecurity.org>

Disk /dev/sdc1 - 1000 GB / 931 GiB - CHS 953867 64 32

     Partition                  Start        End    Size in sectors


No partition found or selected for recovery



Any idea?

Thank you.

Can you retrieve a SMART report with smartmontools?

Can you read sector 0 with dd or a hex editor?
