Moreover, addressing a single block the same size as the disk sector size, one at a time, is overkill in terms of efficiency and wearing for the hdd. Hence exec times for typical operations may well skyrocket x1000 or so. -- paolo -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
