I believe Satoshi Asami was attempting to build a CCD array in excess of 1TB. A number of fixes went in as he hit some of the larger amounts of disk. It may not have been Satoshi; it was one of the guys at Berkeley itself, but my memory says "Satoshi". I don't know if he tried a dump/restore on it; I think he was spending all his money on disks, not tape robots. ;-).
