Windows 10: Why external USB Hard disk is showing in disk manager & device but can't be accessed?

Hi Everyone,


My laptop is Dell inspiron 7586 and CoreTM i7 processor, with Windows 10 Home.


Recently my USB external drives 1GB WD external drive show up as INTERNAL Basic drives and not as REMOVABLE devices in the disk management.


Even the external drive is labeled as basic 931.48 GB Online, Healthy Primary Partition. The hard drive is detectable in Device and printer section. But it can not be accessible.


This is very annoying, since I can't use the USB bootup option... because USB device is not seen by the PC!


I read "everything" I found on the internet, but nothing really worked, so far.


Can anybody help?


Thanks a lot in advance.

:)

 

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!

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.
