Your best bet for complete recovery is SpinRite 6, from Steve Gibson's company, GRC.COM. It's cheap, fast and creates a self-booting CD or diskette. It will do the best of anything I've ever seen to recover data. Then dump the drive and replace.

Quite commonly on external drives the usb interface will go bad in the external drives the hard drive enclosed is probably functioning ok. Would try a different usb cord just to make sure the cord is not the issue. If still does not work you may need to purchase a new enclosure that will have a new usb interface circuit board with it. If taken in for service they will probably tell you to purchase a new external drive. Here is a video on recovering data a side from an external drive.Some steps are not necessary if you have access to an ide/sata to usb adapter. These are pretty inexpensive on ebay as well as replacement enclosures.
1) All you need is a *bootable* Windows CD/DVD.
2) Go to your BIOS, choose First Boot device as 'CD/DVD Drive"
3) Second Boot device as HDD
4) Insert the bootable Windows CD/DVD into your CD/DVD Drive and install Windows from it.
For the Seagate hard disk model ST3120827AS, the TVS diode is typically located on the circuit board (PCB). TVS diodes are designed to protect electronic circuits from voltage spikes and transient events. They are usually small, with two leads, and look like small cylindrical or rectangular components.To locate the TVS diode on the circuit board, you may need to refer to the hard drive's datasheet or schematic diagram, if available. Additionally, you can try searching for online resources or forums where individuals share information about hard drive components and their locations.Regarding the Cisco Nexus Network Switch , it's important to note that specific details about the internal components, including the location of TVS diodes, may be proprietary and not readily available in publicly accessible documents. For detailed information about the switch's internal components, you may need to refer to Cisco's official documentation or contact Cisco's supporthttps://www.serverblink.com/n3k-c31108pc-v-cisco-nexus-network-switch/
Try downloading TESTDISK and see if the drive is detected on the List within TESTDISK. If it is then you may be able to restore the boot sector within TESTDISK.
You will need an external Hard drive adapter case.
This will probably come with driver disk.
If already and external drive it may have internal firmware which talks directly to the PC.
Just install drivers, if any, and plug unit in.
Follow screen prompts.
You do not say what OS you were installing, and Windows limits what you can do with the hard drive during installation.
As you have found out, any power interruption during an installation will likely corrupt the process and make the system unbootable.
If you can restart the install at the very beginning that may work for you. However, I believe the simplest fix will be to use a live system bootable disk and erase the corrupted partition table on the drive then restart the install as if it were a brand new hard drive.
For that type of recovery I use gparted, which can be downloaded for free from http://gparted.org/livecd.php
Gparted live can be used on CD, hard disk, USB, or even pxe boot. I would delete all the existing partitions that were created during the failed install, then restart the install from the very beginning as if it were a new disk.
The hard disk must have crashed and only professional data recovery service providers can retrieve data from the hard disk. It will cost money and if the data is extremely important then only you should opt for data recovery.
You mean "lost" photos? or I don't understand your question. If lost, there are a number of "free" recovery software solutions as well as purchase type solutions. Otherwise, tomshardware.com has very good answers.
