August 5, 201114 yr I haven't rebooted the machine yet. I've captured the syslog (attached). Anyone have any idea about this? Is my USB stick fried? I've only had it about 6 months. If I reboot, will I be able to recover anything off the USB stick? There were some script files I was working on there that I don't have a backup of. What can/should I do next? Here's an extract from the log, at the point where I think all the trouble started.

August 5, 201114 yr A reboot will probably get them back. Apparently, your USB device disconnected, so all reads of it fail. (You could try un-plugging and re-inserting the USB flash drive, but it might not work if the port has been disabled by the OS)
August 5, 201114 yr Author Rebooted, and it came back up and started a correcting parity check. Is unRAID supposed to do that? Shouldn't it do a non-correcting parity check, and at least require me to confirm that I want to correct parity before making any changes?
