Windows 10: 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?

Cannot see my ext WD 2 TB HDD


Ran into this problem transferring media files from my laptop to the WD ext hdd. Both USB 3.
"My Book", my 2 TB WD ext HDD I cannot be seen on my laptop nor my media mini pc
I found it in Disk Management. It is shown as Disk 2. It has a black streak all the way (full?) It has excess of I,8 TB used and indicates that it is unitialized.


I have attached a snipper capture of the disk management page.

How do I get the ext HDD to function without losing all my media? I am not technically savvy, but can follow step by step advice.

Thanks

 

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?

Hi Johan,

It is possible that your
HDD was unreadable
causing the error message to appear. We recommend that you perform these troubleshooting steps and check if there are any changes:

• 
  Shutdown
  your
  PC.
  
• 
  Unhooked
  the
  HDD
  and
  turn on
  your
  PC.
  
• 
  Reconnect
  your
  HDD
  and
  restart
  your
  PC.
  

If the issue persists, we suggest that you contact your
laptop/computer's manufacturer
for further assistance.

Update us on how it goes.
