Interesting suggestion, certainly shouldn't hurt.  But AFAIK the device 
mapper runs in the kernel and it's going to do it's "own thing" before I 
get a chance to hdparm it.

That's why I'm most interested in determining what (if anything) a LVM 
configuration does ... especially in situations where it detects a 
bad/repairable configuration (if that even makes sense).

Regardless, I'll do some experimenting - not sure if there are going to 
be any limitations with hdparm and configuring my disks via a USB adapter.
