My external hdd was not connected while the formatting n installation process. I tried all the possibilities which i can do to detect the hdd, it is not detected in My Computer-Device Manager-Drive-Disk Management , but it can be seen in device&printer.
Finally, I updated win 7 to win 10 still is was not detecting. Then, in Device manager - Storage Controller - Right Clicked USB ATTACHED SCSI (UAS) Mass Storage Device and Clicked Enable option on dropdown menu and then Seagate BUP Plus Slim BK SCSI Disk Device shown in Device Manager - Drive & Disk Management.

Hello paragbhandari!

This is unpleasant, I understand! :/

from what is shown in Disk Management I can see theree drives, the third (DiSk 2) which is 1TB and suppose that is the external? It says it's Unallocated, meaning that there isn't any partition table for the system to recognize. :/

Anotehr thing I am seeing is that partition/drive E: of 174GB is RAW, meaning there isn't a file system on it recognizable to the system. There is no access to that drive, as well. Had you noticed that?

I would suggest you to first change the cable of the external drive. Then, use its dedicated software to check its health and SMART values and if/how it is detected. Try it on another system.

Post back screenshots of all results.

I would also suggest booting to a Linux-based Live CD and checking whether you can access either the external or drive E.

Create Live Peppermint CD/DVD/USB:
Peppermint Live CD/DVD/USB - Create for Emergency Backup

Good luck and post back! :)
