External hard drive not recognised

[scopio]

Problem:
I have two external hard drives that I have been using for backups etc. on my desktop running Windows 10 Home. I connected the external drives to my HP Laptop running Windows 7 Home Premium SP1 to copy some files and it has changed the ownership to the external drives laptop user!
Now when I connect the external drives back on my desktop running Windows 10 Home the drives are not recognised and don’t even show in Disk Management have tried to connect the drives in different USB sockets to no avail!! When I plug them in the pc makes the connection sound but the drives do not appear anywhere!
Question:
How can I get the external drives to be recognised and change ownership back on my desktop running Windows 10 Home??

Hi Compton, could you please elaborate your response, for example from which pc do I need to uninstall the external drive from the laptop (which recognises it or from the desktop which is where I want to use it)?

Unable to uninstall the external drive from Device Manager or Disk Manager as the external drive does not appear listed at all on the desktop!

OK got there in the end   It was listed under Device Manager >  USB Controllers with an exclamation mark with the error saying that "the driver for this device is in memory". I uninstalled it from the USB Controllers and it worked. Previously I was looking in Device Manager > under Disk Drives and in Windows Explorer under This PC (Computer) where it was not listed!
Thanks for your help and like I said I got there in the end.
