Yeah.  I don't know what I was thinking.  I've been using scsi stuff since 
'96, so I really have no excuse.  I know that you always chain from drive 
to drive, I don't know why I did it like this...

So my problems probably start there, and end with IBM crap drives.  Does 
anyone else here have any stories to share with Adaptec/DPT raid 
controllers and IBM drives?  The other systems that I've had problems with 
drives going to "failed" state were cabled properly, but also exclusively 
used IBM drives from the "dark years" of IBM and/or Hitachi.

Thanks very much,

Charles
