I have 7 drives that are attached via USB to the Unraid box.

All show up fine in Unassigned and are Shared out, making them accessible over the network.

However, after a period of time, the drives show as if nothing is on them.

root@Tower:/mnt/disks/S-01# ls
/bin/ls: reading directory '.': Input/output error

I've tried unplugging the drives and trying a different USB port but they still stay this way.

My only option is to reboot the Unraid box and then they start acting normally again for a week or two.

 

Any thoughts or suggestions regarding this?

I kind of think that there is an issue with Unraid and USB controller.

Hopefully you unmount the disks before you unplug them.  Based on your log, it appears you are not unmounting first:

Or, the disks are dropping off line and creating a lot of ntfs issues.

You were correct. I tried unmounting and remounting and they showed up.

However that brings up a good point to have a good UPS on the portable drives. I think we lost power and for some reason I didn't have these drives on UPS.
