Thanks for the quick reply Actually I managed to fix the issue by using the patches here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=436703 After using that patch, no more "clack" > Don't have any debian around but apparently it's > issuing spin down for > /dev/sdX's too. The patch still doesn't solve the missing flush-cache, however after seeing the code, seems that the origin of the problem was that shutdown was NOT issuing spin down at all (for sdX). > > 4) What everyone in forums is asking... are they > SATA > > drives being forced from long time ago, and they > have > > just found out by using the new kernel?

They're wondering if before kernel 2.6.22 their SATA HDDs were making emergency shutdowns and didn't realize that they weren't normal shutdowns. And they may have been using Linux in their SATAs from a long time ago, just to realize now (thanks to the new K2.6.22 warning) that they were damaging their HDDs since years. In summary: the emergency shutdowns issue appeared in K2.6.22, and using previous kernels fixes it, or the emergenct shutdown happens in any kernel version?? I can't answer that question by myself, because I've just installed Linux in this HDD and upgraded immediately. > Sure way to tell is to look at emergency unload > count int the output of > 'smartctl -a'.

Thanks, but the idea that software can do such thing gives me the creeps. > Opcode 0x94 is retired now and it's probably not too > good a idea to > issue it to modern disks. 0xE0 should be good > enough Don't blame me, it's in Debian's src.

May be I can submit a patch... However the patch I'm using doesn't trigger FLUSH but the problem is solved anyway.
