https://bugzilla.novell.com/show_bug.cgi?id=229914 ------- Comment #12 from bjoern.wahl@hospital-borken.de 2007-01-17 05:54 MST ------- Created an attachment (id=113350) --> (https://bugzilla.novell.com/attachment.cgi?id=113350&action=view) notihing Assuming that hdparm shows the wrong results I tested copying the dvd-image on the harddisk, and there a can not find any difference between 10.2 and 10.1 so maybe it is really only a bug concerning hdparm an not the real world performance.... I keep an eye on that and here are my results... opensuse10-2-kernel2.6.19.2 linux-h4hs:/tmp # date && cp openSUSE-10.2-GM-DVD-i386.iso openSUSE-10.2-GM-DVD-i386.iso2 && date Mi 17.
