plug it in and not recognized at all. is there something special i need to do to get this to work? it works fine on my computer.

[Q] External USB drives (HDD/SSD) and mounting

How does the SATV decide what directory it will mount an external USB drive to?

/mnt/media_rw/usbdrive
/mnt/media_rw/usbdrive2
/mnt/media_rw/usbdrive3

I keep noticing mine will change from one to another each time I reboot. This is really messing with Foldermount. Does it matter what other devices are plugged in? How can I force it to a certain one? I am rooted so if this can be done from terminal, I assume it's *NIX like, I'm all ears :)

thanks
