The history is like this :
I have a 2TB Seagate USB 3.0 Hard Disk Drive (HDD) full of movie files which recently was very slow to open the folders in it (also slow to load the file when opened).
Although Windows 10 say that the HDD is healthy and already optimized, because of the slow to open/load, I optimize the HDD using Defraggler, a free software from piriform. Up until 83% the progressing bar in Defraggler stop "forever" (after I've waited it for almost 2 hours).
I can't shutdown the computer directly because I need to close the Defraggler first.
But even after I click the STOP button on Defraggler, after I've waited a long time, it still didn't stop. So, via Windows Task Manager, I "end task" the Defraggler. Then the Defraggler close.
Since that time already late at night, I didn't check how is the HDD at that time (after Defraggler close via "end task" in Task Manager). I just directly shutdown the computer, but then the computer didn't want to shutdown. It just hanging there with a message "shutting down". After I unplug that HDD, then the computer can shutdown.
This morning I turn on the computer without problem.
When I connect that USB HDD, the HDD led is blinking, the Windows Explorer of "This PC" show a progress bar on top of the window and this HDD show but only a drive icon with a drive letter. So I wait until the progress bar full, but still in "This PC" explorer, this USB HDD only show a drive icon with a drive letter (this HDD led still keeps on blinking). There is no icon shown up in the taskbar for the connected external drive, so I can't do the "eject" safely this HDD.
So I just unplug this HDD, and I plug another older 2TB USB 3.0 HDD. Windows 10 directly recognize it, "kling" sound is heard, and in the taskbar for the connected external drive, this older USB HDD shown up. All is normal with the other two 2TB USB3.0 older HDDs.
I shutdown the computer. Unplug the older HDD, plug the "problematic" HDD. Turn on the computer. But Windows won't start, it just hang there with my motherboard logo "forever". Only after I unplug that "problematic" HDD, then the Windows can start. And this happen after yesterday I optimize the HDD with Degfraggler.
So this "problematic" HDD when already attached to the computer is causing Windows unable to start and Windows unable to shutdown. If it plug after the Windows start, Windows unable to detect it (showing a drive icon and drive letter only) and the taskbar for the connected external drive also not show up.
I've searched the internet and found some articles with similar problem, and mostly the article's solution is to do file recovery via third party software.
Since I think that to do a file recovery is my last resort, I would like to know if there is still a way to fix this, so I don't need to do the file recovery.
Any kind of respond would be greatly appreciated. Thank you in advanced.
EDIT:
Below is the "This PC" window :
Below is the task manager of that Drive P :
And below after cannibalism:
From youtube, I saw Seagate cannibalism - and it has SATA port + power port.
But it seems mine doesn't have it. Is there still a way that I can connect it internally ?
Oh ya I forget, when I open Disk Management, it unable to show all the hard drive attached to the computer unless I unplug that Drive P.
