There's no sleep mode and a crash would not run the scripts that change the colors of the leds. The only plausible explanation I can think of is that it (paniced?) rebooted and failed to mount the usb disk when booting. You may be able to get some idea by looking at the logs. Enabling bootlogd in /etc/default/bootlogd should make the console bootup be logged to a file as well, though this won't help with things before the disk led comes on. FWIW, "brick" is usually reserved for issues that can't be recovered from without hardware modification. -- see shy jo
