Yeah I agree they are difficult to deal with sometimes.  And expensive.

I agree the restriction should only apply to the place where I install the application.  
I told them that two years ago and they said that's the way their software is designed, to prevent 
installation if RAID 1 is detected, that's what the tech support guy told me anyway.
They want to prevent someone from taking a mirrored drive and giving it to someone else to use
on a different machine.  They told me this two years ago not sure if they have the same policy though - 
but my version is about two years old.

I could clone just my data somehow on a seperate drive or backup (not the applications and OS),
yet I also want to clone the entire OS and applications
that's where most of the time goes into as far as restoring a disk or buying a new disk
is concerned.  I'm paranoid because I've had 3 crashes in the past 4 years and it's always a pain
delays my work for days.  SATA drives are made cheap compared to server grade SCSI's.
