Backup Error : Destination cannot be mounted on the system. ReadyNas 102
I had an issue with the backup jobs not working. I checked both backup drives. I run seperate backup jobs on each drive. They are Toshiba 2Tb 2.5" HDD's. One needed repairing, so I connected it to my...
If the filesystem isn't unmounted safely then it can lead to the filesystem being marked dirty and going read-only.
Connecting it up to your PC and repairing it can be a good way to go.
If that doesn't resolve it (i.e. problem comes back quickly despite safely unmounting the USB disk) then you could try formatting the disk again and seeing if things work better with a clean filesystem.
If that still doesn't resolve it perhaps check the USB disk using vendor tools. If the disk is failing that could explain the problem too.

So is this the Nas causing this problem? Interesting since I have 3 major issues with this Nas now.
I cannot turn it off nicely. I keep pushing the button and nothing happens except the LED flashes for a while. I had to pull the plug. The admin page was not loading the details. Just showing a progress indicator for 10 mins until pulling the plug. Speaking of which, I plugged in the 2nd USB HDD last night. It worked perfectly on my notebook. I setup a backup job and started a backup. If I had not pulled the Nas plug it would still be going, well over 12 hrs later. How long does it take to do a backup on less than 400Gb of data? I have deleted both backup jobs.

Is there another way? I am not aware of one.

These disks were both new last August. The only thing they have been used for is Nas backup disks and as the Nas keeps failing these, not very many. If there is a problem with the format then it was caused by the Nas. We had a lengthy power failure a while ago. The relevant log details:
Thu Jan 7 2016 17:12:27: System: ReadyNASOS service or process was restarted.
Thu Jan 7 2016 16:40:21: System: UPS UPS () battery is low. System will shut down soon.
Thu Jan 7 2016 16:21:53: System: UPS UPS () is on battery power.
Thu Jan 7 2016 13:47:42: Backup: Saved backup job Backup1.As the UPS did its job properly as far as I can tell, this power failure did not seem to cause any problems. There was a successful backup completed the next day as well.
The Nas has finally shut down so I pulled both USB drives. The one re the thread title did not show any errors. Windows did a full scan. The other drive had errors which were fixed.
I plan on copying the entire contents of the Nas to another external HDD for safety if I can. The 3rd issue is with very slow access. I have already spent more time on these problems than I think this Nas is worth. I am considering getting another Nas. Not Netgear of course.
If the filesystem isn't unmounted safely that would typically be caused by user error.
Repairing the disk using your PC is the way to go.
Which services and apps are you running?
Which firmware are you running?

I I unplugged the Nas, granted. But if the Nas has been trying to do a simple backup for over 12hrs, the admin page is flakey, keeps restarting and when it starts won't give any info except for a busy icon. When it refuses to turn off by the usual methods outlined in the manual (a situation that has existed since I first got it) you have got to accept that there is no other option if one wishes to get somewhere.
On the other hand :
Mon Jan 11 2016 12:22:29 : System: External storage 'TOSHIBA_MQ01UBB200' might not have been safely ejected after last use. This device will be read-only. Plug it into its native operating system and repair it before it will be writeable.
Mon Jan 11 2016 12:19:24 : System: External storage device connected.Cannot blame the user for that one.
This all tells me that there is some serious problems here and I am getting nowhere and as I said I have already spent over my allocation of reasonable time to sort this problem out. A sensible person recognises that there is a point where you should cut your loses and go elsewhere.
I have yet to see any indication that you know anything about the problem. This is not a dig at you, just a comment that there are too many problems to deal with in this manner.

However I have to say that this is not the way to go. Look at this from my position.
I connect the USB HDD. I try to do a backup. It doesn't work. I remove the USB HDD and repair it.
Repeat previous step.
The way to go is to have the Nas do automatic backups without having to do the USB HDD 2 step constantly.
