:Drives connected via EHCI, both externally powered (3.5 inch drives).

    Externally powered means it can't be an overcurrent issue.  Shoot.

    It could be an EHCI issue, or it could really be bad blocks on the
    drive (though that seems less likely).  Do you have any problems when
    you do not load EHCI and just use OHCI ?
