As it turns out, data seems to fall off the 16Tb drives after ~20 days.  Which makes it a good thing that I saved all of my raw data from my good Mode Cleaner / seismic weekend for offline Wiener Filtering in the following secret place:

/cvs/cds/caltech/users/jenne/AdaptiveFiltering/mat/MCseis_raw_data_7Aug2010

It's not linked to the svn, since it's a boatload of data.
