external USB harddrive not recognized when present at boot
hi guys,
i posted this question originally on debian-user, but was suggested to
post here as well...
i am encountering an interesting (and annoying) problem. when the
external USB harddrive is plugged in during boot (i have dell d430 with
d/port port replicator - the drive is connected to one of the usb ports
on the d/port), i can hear it spinning in the very beginning, but then
it powers down and won't get recognized. it's neither shown in
/dev/disk/by-uuid nor do the udev rules apply to create the node in /dev.
apparently, it has something to do with this error showing up approx. 4
seconds after the boot start, at the time when the drive spins.

since after unplugging and plugging again, the harddrive is recognized,
udev plays its part and i am getting the respective device nodes in /dev.

this is on lenny/amd64 with up-to-date installation. on my previous
laptop with etch, even when the drive was present on boot, it would be
recognized and taken care of by udev, iirc (it would spin immediatelly
on boot start and then once more during the boot procedure).
does anybody have any hint as how to proceed from here?
thanks,
lubos
