Power Went Out When Moving User Accounts

I have two WD Blue 1T Drives. One was filling up with pictures and games used by three people, plus all the apps, so I was going to do a clean install, and put all user files on the second WD Blue 1T drive. (I bought the second over a year ago with intentions of doing it then, just never got to it, so the second one was blank and formatted when I started.)

Of course, the power went out during sysprep. Now that power is back on, neither drive shows up; it is as if nothing is on either of them. I used a cord to connect them to my laptop and one shows up in the file explorer (the one I was moving files to) but not in disk management. (Yes, happily I had backed up all important stuff so there is no data lost, whew!). The other one doesn't show up anywhere. I don't have another desktop to put them in to try, only the one and the laptop where I connected them to.

Am I stuck with data I can't get to because both these drives are bricks? Is there anything I can do to fix this? Or just throw them away?

Is there a way I could use Linux to "see" them then format them and use them as if nothing happened?

Welcome to the forum. Can the BIOS see the drive if it can't it's dead power off could corrupt the drive but rare to kill it

If you see the device in BIOS, then, as said by Samuria, you still have a hope.

If this is the case then you can use any Live Recovery CD, like Hiren Boot or similar, in order to format your drive and get it back to life :)

I've seen it happen once and a problem occurred in that the Source drive got changed to RAW format, rather difficult to deal with, get the files copied off.

And thanks to everyone else who responded.

Yes, both could be seen by the BIOS. What had apparently happened is the formatting, or something, disappeared from the new d:\user accounts drive. I made that my new c: drive and clean installed Windows 10. (There's another whine about that, I'll add it to this one below).

Then I used the trusty EaseUS, which I had from years ago, and broke all the partitions, then formatted the other, original c: drive and used it as a d:user accounts drive.

Thanks for the BIOS idea. I would never, ever have thought to look there, truly!

My whine, which is posted in another thread, is now I am stuck with Windows 10 HOME, instead of PRO, which is what it should be. How do I fix that???? I skipped the key thingy in the install, as it was supposed to already be in the machine, and my system is showing activated, genuine, etc., only HOME. My screaming, whining, etc. is in another thread, so I'm marking this as solved.

Thanks to all of you!
