    Hard drive shows up in device manager but no in disk management


    I have a few months old Seagate 2tb HDD that just today began to not show up in my drives in file explorer. After screwing with SATA and power cables (to no prevail). It was previously assigned a letter and didn't show any sign of failure, any help?

    :)

    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.
