Backup not finding my Seagate expansion drive.

Hi,

I am running Windows 10 Pro Build 1703, prior to my update I was using my external Seagate
drive as my backup location, however since the update, backup is not finding the drive.
The drive is working perfectly for all other tasks and is shown on Disk Managment as a "healthy" drive".
I have tried everything I can think off including manually entering the drive location, however, Windows
comes back telling me the location does not exist!.....Err....Yes, it does!!

Any assistance would be most welcome.

Hi I am trying to backup my system using backup & restore Windows 10.
As I mentioned in my earlier post, the drive is accessible for all other tasks other than Windows 10
backup utility accessible via all settings....

To be honest, most of us here have stopped using Windows backup and restore because it has proven to be too unreliable. You have now experienced part of its unreliability. Third party imaging programs have proven to be much more reliable and flexible, such as Macrium Reflect:

In fact, I just went to Windows backup and restore to see if I had any problems on my computer with it seeing an external drive and mine says "This feature is not available in a portable workstation environment". So, due to it's unreliability, I can't even get into it to try to help! I wouldn't take the chance of having to face one of the problems we now both are having when it came time to restore my backup because of a hardware failure.
