That would be nice as a recent install at work using an Asus MB w/ Adaptec built in, plus a Seagate ST19171W (? aw, heck, its a full height 3-1/2" 9G drive) produces a message "reducing tagged openings to 64" quickly/instantly followed by another dropping it to 63. Its quiet after that. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
