Question Most of the time when I boot up, one of my HDD is not recognized and I have to assign a letter to it

[MutantMike]

So I was using a data recovery tool "TestDisk" and I think I did something wrong, I used option for not being able to find a drive or something

But anyway ever since that 2 days ago when I restart my PC, over half the time my D drive in disk management just states "new volume" and I assign D for it



Why does this happen and can I make it stick to D instead of reverting to just new volume most of the time after I turn the PC off?

Did you check drive's health ?
Hard disk sentinel for instance

and Mini tool partition wizard to check file system ?
