Your troubles are symptomatic of using a standard IDE/SATA driver instead of
the RAID driver.

Nevertheless I would agree with other posters that RAID is best confined to
enterprise-class server iron. It has no proper place on a desktop.

IME it may not anyway. I've seen cases where a failing disk trashes the data
on the communications bus, corrupting both. Here again it is the difference
between a mickey-mouse 'RAID' implementation and a true duplex SCSI interface
that matters.

For a better means of protecting your data with two disks, check out Lazy
Mirror.
