SGP/EBBR/E8 - Data Corruption and Loss

Data loss was experienced during the periods indicated for unknown reasons.
My understanding is that ingestion of the data failed for these periods
because the record length was shorter than it is supposed to be.
Site Operations personnel visited the site on September 7 and powered down
and then up, the EBBR, essentially causing a reload of the CR10 program.
All output locations had been -9999 or 0000 when they had arrived.  The
battery condition was normal.  Failure of a portion of the storage module
may be indicated; data sneakernetted from the storage module shows an
alternating sequence of two days, September 2 and 3 and then a stretch of
garbage characters.  No other days of data are found.  The portion of the
storage module memory that contained the program was not corrupted, as the
CR10 program compiled and ran properly when it was reloaded from the storage
module.  The data after the period above is reasonable.  The last part of
the storage module memory may be bad and perhaps in trying to access it
remotely multiple times the situation above resulted.

No recovery of the lost data is possible since the storage module data
are missing or corrupted.
