We have lost one head-disk-assembly to a head crash; losing a 500MB file structure is no fun. A site nearby has lost 3 HDAs in about the same period of time. Be careful about non-DEC memory in 780s with RP07s using the 2.2MB/s transfer rate (with dual mem controllers). It seems that a number of mem boards (many of DEC's included) don't quite make the grade on timing, and haven't been fully exercised by previous controllers. Some of our DEC and non-DEC memories have had to be replaced to shake out nasty system failures. -------
