Umm ... "huh?"

All three of those disks are used *quite* heavily... This is on my 
workstation ... I'd know if it crashed a lot :-)  Granted, this is an 
SS2, but esp/dma revision on my SS2 is the same as on the SS1+'s around 
here...What are the revisions on your SS1+ hardware?  (Note, my SS1 
systems are rock solid with 2 disks, too...)
