    EXT HDD Show "Online" but are "Offline" After Clone (Can't Format)


    I'm on Windows 10 Home, using USB 3.0 EXT HDD (one Glyph & one Fantom)

    The Problem: I attempted to clone each drive using Macrium Reflect as I've done many times before to back up information. Something's up because both drives seem to be bricked. At the moment that is.


    • If you look disk.jpg you'll see the drives highlighted clearly showing "Online".
    • Then in cmd.jpg, again highlighted "disks" & associated "volume" information. Notice how the volumes say "offline".
    • Finally in format.jpg, you see the Disk Management error popup when trying to format Disk 5. Same thing for the other disk.


    Attempted: I've tried numerous things in Disk Management such as: a) deleting the volume, b) reassigning a simple volume, c) assigning a drive letter. In powershell, same attempts just in command line/powershell. Mainly attempting to convert these offline volumes to online using:

    Code:
    "select disk 2", "offline disk" | diskpart

    and to put it back online:

    Code:
    "select disk 2", "online disk" | diskpart
    No change. Unable to reformat & use either drive. Active/Healthy partitions w/ assigned letters or not.

    Any ideas on how I might recover these disks? It's unclear if beforehand these were "dynamic drives" or not, they show "Basic" now.

    Any help is appreciated.

    From the title, I understand you are trying to format the drives and make those workable. If that is,

    Try formatting the problem drives with HP USB Disk Storage Format Tool v 2.2.3. ( You have to run it as administrator)

    Try unplugging Just one of them. Check plug back it and do the same as the other.
    Its may be (longshot ) that the two drives ids are similar enough that it is confusing the system.
