Hi Jeffrey,

Thanks.  I use tw_cli too and I have scripted a check to see if it 
degrades but this doesn't help with checking for disk problems before 
they happen which SMART should help with.  As it happens, smartctl works 
with 3Ware SATA drives.  It is my other SATA drives that I'm unable to 
monitor.
