I'm still having the problem. I tried a reset, tried restarting the usbdrive1, reformatted the usb drive, everything short of reflashing the firmware. The unit is actually a 320, not a 250 as I earlier stated. The firmware in your database says it's 1.11, which is what the unit came with and I'm using. Are there any other backup options that I can use for a complete backup of the linkstation to usb (outside sources)? I'm really frustrated by this as we have important files that are not getting backed up: We're using the linksation as a file server on the network. Any further ideas? I'm feeling desperate at this time!
