Many moons ago (I will show my age by this description) a company called 
Sola made a thing called a "ferroresonant transformer" ( 
http://www.solaheviduty.com/).  These things were "the standard" for 
line glitch removal before there were UPS, and they really are 
bullet-proof when big glitches are the issue.  They are quite literally 
incapable of passing anything other than 60 Hz.  And they are Not Cheap. 
  And of course there are two grades of UPS:  the ones that kick in when 
the power goes off, and the ones that are always running, i.e. they are 
actually battery chargers and they are constantly generating line 
voltage off of the battery.  But I'm sure you know that.

It does seem odd that you should blow just drives and not motherboards, 
unless you don't have the standard configuration where the power supply 
that powers the MB also powers the drives.
Do you have drives and MB separated?
