HDD randomly disappeared from "This PC" but shows up in disk management as "unallocated"

[Varpin]

Like the title says. Windows allows me to initialize the disk, I have everything backed up so I could do that, but I would like to try and fix this some other way first. I unplugged both SATA and data cables, but that didn't do anything. Also tried updating its driver. Everything worked like normal 24 hours ago, noticed that the drive was missing when I was trying to launch an app installed on it. (2 screenshots, Disk 2)

Very weird indeed. Most like dead though. You can try format the drive, but not sure'll work.

What does CrystalDiskInfo say?

It can't see the drive, I tried scanning for new drives

Try another SATA cable and port, maybe connecting it to another machine entirely... if it's no better, dead drive.

Consider it as dead, you should backup all files if it was suddenly recognized

How old is this drive?

[Needfuldoer]

It's detecting it as a 3 GB hard drive. Either that's a very old drive you're running for some reason, or the drive itself is dead.

Oh wow I didn't even notice that before! it should say 3 TB. So most likely a dead drive...

About 6 years. It's most likely dead, I just noticed that it says 3 GB instead of TB in disk management.

Is it a Seagate? IIRC there were some 3 TB Seagate models that were known to brick themselves.

@NeedfuldoerYeah, its a Seagate ST3000DM001

[SpookyCitrus]

Yeah this is common behavior of a failed drive, not really anything you can do to fix it nor recover the files off of it. If the data is unimportant, simply just replace the drive. If the data is important, looking into recovery options would be the next step.

Oof, yeah I think that's the one with the bad firmware.
