Actually the controller is on the drive now, not on the motherboard. This has been true since the adoption of IDE. The motherboard host adapter or interface is only passing commands to the controller which is actually on the disk. It is a historical semantic misnomer that we call a host adapter a controller. So by changing out the drive you are effectively changing the controller. Of course this says nothing about bad cables or bad power etc. -----Original Message----- From: fedora-list-bounces@xxxxxxxxxx [mailto:fedora-list-bounces@xxxxxxxxxx] On Behalf Of Alan Cox Sent: Tuesday, August 07, 2007 7:59 AM To: For users of Fedora Cc: fc-cornette@xxxxxxxxxxxxxx Subject: Re: fedora 6 kernel panic issues > effecting the other drive as well.

A parallel ATA controller setup means the master can take out the slave and vice versa. SATA is one drive per cable which prevents that happening. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
