    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.
