Internal hard drive inaccessible with a question mark

Hello everyone,

I'm reaching out because I have a problem with a hard drive that has become inaccessible and shows a question mark in "My PC".

Having read another thread from someone who had a similar problem, I've tried several things (I hope I did it correctly), but nothing worked.

Here’s the view I have:
Hello,

I tried going into Windows Disk Management but I no longer see my drive E:



and also no error in the device manager:


I tried the CrystalDisk software and similarly, my hard drive does not appear:

Finally, I tried DriverCloud (and there I updated all the drivers automatically, at least I think so because every time I do it, new drivers appear to install).

So...
I'm a bit desperate because my E drive contains a lot of important documents.
I probably misused one of the tools above, or maybe there’s still something else to do? Or maybe my hard drive is dead... and that would be a disaster.

Thanks in advance if you have any ideas :)
