    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[/quote]
    and to put it back online:
    Code: "select disk 2", "online disk" | diskpart[/quote] 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.

    :)

    Printers, ext HDD not recognised

    Upgraded to Windows 10, initially, printers & ext HDD for backup all worked OK. Few days later, all stopped working, nothing visible in Devices window. Subsequently downloaded updates KB3081449, KB3081452 on 28 Aug followed by KB3081448 on 29 Aug. Full
    functionality returned. Backed up on 30 Aug, used printer on 01 Sep; no problems. Today, printers visible in Devices, but marked as offline even thought they are switched on. Ext HDD not visible at all. What's going on and how can I fix it?

    Failing HDD and Cloning

    You seem intend on this install clean install windows when I have said windows does not run on that drive and TeraCopy doesn't even budge anymore.
    for moving files from that drive. Then there are those that have suggested imaging and 1 or 2 that talked about cloning software.

    I now have 3 HDDs left...

    So nothing is copying, no cloning and imaging, now what?

    computer stops recognizing 2 ext HDD

    I use a 7 year old HP Pavillion desk top and so far it has worked well. I have USB connected 2 ext HDD. One is basic storage and the other is my ext backup HDD. If I try to open a file in either of them, my computer stops recognizing both the ext HDDs causing
    a major problem creating backups. The only way to bring back recognition of the drives is to reboot. I plugged the two HDDs into another computer and they were fine there. How do I fix this?
