[Tinyos-help] External flash unresponsive after GoldenImage

Some of my Mica2 motes have become hadicapped after being programmed with
and rebooted to GoldenImage. What I mean by handicapped is that they still
function with basic apps such as Blink, but seem to have trouble with
programs that require the use of external flash. For example, running
Deluge2.0's FormatFlash leaves the red LED on now, whereas before, the green
LED would light up a second or two after programming. As for reinstalling
GoldenImage again, it seems to skip the copying-itself-to-external-flash
part (no blinking of the yellow and green indicating copying), and instead
does a normal startup and goes quiet afterwards.
I can't quite pinpoint what exactly causes this; it's happened to 3 out of
20 motes I've reprogrammed over a span of 2 hours, and I'm somewhat worried
that the remaining 17 might face the same fate. Any suggestions as to the
source of the problem would be appreciated; methods for resetting the memory
or the entire mote to factory settings are also welcome.
