Habe gerade mal danach gesucht, es scheint wohl tatsaechlich die Firmware zu sein. Damit hast du auch die Loesung parat, du bist gewzungen, dieses Programm zu benutzen, um den Kram abzuschalten.
Ich habe nun auch einen interessanten Thread gefunden: http://groups.google.com/group/linux.kernel/browse_thread/thread/505ccf76002... Al Auszüge daraus: WD is not the first to do this unload nonsense, I've noticed it with Toshiba before: http://lkml.org/lkml/2006/11/15/413 Since then, I am dependent on the thkd[1] module and no hdparm is going to fix it; the module does a dumb read every now and then on one device, causing streaming performance to kink periodically, but it works at least at keeping the disk alive. (Reason it's in kernel: better to have even when userspace is not running.) Improvements welcome. ;-) Yuck, how stupid! But the solution is simple. Make sure to get a warranty of much more than 80 days. Use RAID-1 (or backup often). Just let those disks destroy themselves (they _are_ faulty) and get new ones all the time. As long as they make them this stupid, you won't have to buy new disks again. Free warranty replacements forever. To be a bit more constructive, tell them about this strategy. Perhaps they get busy fixing the firmware? Christian Pernegger wrote:
Being able to set the timeout online via hdparm would be nice, too :) That can be arranged. I just need a copy of the DOS utility that does it now.
