Windows 10: Hard Drive isn't showing up on file explorer, device manager, nor disk manager, after...

My PC froze, and i waited maybe 10 minutes for it to work but it didn't and because simply pressing the power button didn't help i held the power button and force shut it down. it happened to be previously many times, and nothing happened after i force shut down the PC. after i powered it back on i realized that i can't see the drive on file explorer.

external hard drive showing up in device management but not disk management

I had a similar problem. I put an old laptop hard drive into a Rosewill USB hard drive enclosure. It showed up just fine when connected to one laptop. However, when I connected it to a different laptop, it showed up in Device Manager, but not in Disk Management
or Explorer.

I double-clicked the drive in Device Manager to get into Properties, then went to the Volume tab, then clicked "Populate." This showed the drive to be "Offline."

To make the drive "Online," I did the following:

1. Go to an elevated command prompt: Right-click on start button > Select Command Prompt (Admin). Enter the following commands (in bold).

2. diskpart

The command prompt will change to: DISKPART>

3. list disk

All disks will be listed. Note the number of the disk you want to make to go online.

4. select disk 2

Instead of 2, substitute the number of your disk.

5. online disk

If this command is successfully executed, you will get a message that reads, "DiskPart successfully onlined the selected disk."

It took me a long time to find this solution, so I'm putting it here hoping that it helps the next person.

 

external hard drive showing up in device management but not disk management

Hi,

I recently tried to use a brand new Seagate 2TB External HD, but it is not showing up. It initially showed up, but after I tried reformatting it to exFAT32, it disappeared from the disk management list.

I then tried:

• refreshing the disk management list,
• inserting into a different USB port,
• re-starting my computer, and
• uninstalling the device from device manager/letting it refresh,

I still can't see it. There is no yellow error in the USB controller list.

I'm on Windows 10.

Intel i5-3317U @ 1.7GHz

Any suggestions? Thanks!

 

Hard drive showing up in disk management but not in file explorer

So I just finished building my new computer and I put a 2 tb firecuda sshd in it. I boute windows fine on my ssd and my hard drive showed up in the BIOS but it didn't show up in file explorer. I went to disk management and formatted it to be a basic drive
but it's still not showing up in file explorer.
