What i should to do to get similar problems? :) Since the topic is here: Can you boot up the machine with that ata HDD offline (unplugged), and then insert it and atthach it? On my 6.2-STABLE machine, I can detach-replace-attach ata disks (most of the time), but only if I have that slot active at boot time. And yes, though I haven't come up with an absolute sequence to reproduce it, I occasionary have the same problem that hot replaced disks are not recognized by 'atacontrol attach', be it the same physical disk or another. I feel there is a 'right sequence' of atacontrol commands (or the lack of), and some 'wrong sequences'. The only way to reattach it then is to reboot the machine. Thanks -- Hiroharu Tamaru
