Hi Mark,

Of these files on /volatile, I see that there are ~750 that are truncated or corrupted in some way.  I am in the process of collecting all of the jobs (both at Jlab and UConn) that completed successfully and staging them on SRM.  When I am done, I will pass you a list so you can pull the lot to jlab and stick them into mss.  Instructions for accessing the files on SRM are on the wiki at the page below.
