Unfortunately I'm not able to reproduce these errors with my HW.
Do you have a possibility to try a different USB stick/storage?
Does the stock EdgeRouter Lite USB stick work?

When simulating some errors I noticed there's a case where the driver
does not recover properly. I'll try to send fixes for that soon.
But that still doesn't solve why get an error in the first place. :-(
