Thanks a lot for describing the steps in detail. Actually, FW 00.07.00 is much more transparent to all this than previous FW versions.
I formatted a SanDisk Ultra Fit USB 3.1 64GB Flash Drive under WIN10 with the WIN standard formatting tool to NTFS (no fast formatting). I did some tests with it, writing, reading, and so on. Yet, after re-inserting the USB Flash Drive into RUT955 slot I could not find anything under RUT955 menu USB TOOLS > Mounted File Systems. I think this is the fault. I rebooted RUT, I un-plugged the USB Flash Drive, I re-inserted it, no change. I even tried another USB stick, nothing changed. I went through a power disconnect/connect cycle, nothing changed.
Is there a chance to verify whether the USB port has a defect? Perhaps under menu Administration > Troubleshoot?
Would you be so kind to assist that procedure?
Thanks in advance, BR Guenther
P.S.: Is it possible with package "Network shares" installed to use it's format tab to format a USB drive to the needs of RUT955? This would be comfortable, because the USB Drive could reside in RUT's slot.
