Best IDE RAID5 solution for FreeBSD 5.2 ?

[Adrian at Connexus]

Hi Andrew,

Thank-you very much..  The HD software found a bug on
one of the drives that hadn't degraded - fixing that
seems to have worked..  I thought HDs were supposed to
fix things like that internally ?!

You saved me lots of time and effort - email your address
and i'll add you to my Christmas card list!!

Regards,
Adrian.
