On Feb 25, 2009, the mcdc server experienced a hard drive error, and data
for sf32000 was lost.  We have been able to recover the bulk of our data holdings 
but there still may be items that have not been restored.  If there is a particular 
data set that you need and do not see, please contact the MCDC and we may be able to 
expedite the recovery of that data set.
