Problem(s) Encountered:

Was doing a long series of exposures of an eclipsing binary.  The first 134 of these were written to the disk properly (/data/mcgraw) but the last 15 were read out but were not transferred to the final destination.  They might be written somewhere else, but I can''t find them and I don''t want to fiddle around when I am sleepy. The system now will not write images.

I noticed an error message ''BUS ERROR'' on the IC screen that shows the image as it is read out.  It appears momentarily, right before the status switches to ''IDLE''.

Solutions:

Data and system recovery for this problem is written up here:
