Where are /dev/sda>15 partitions?

I've got a PATA drive, and I installed arch64 half a month ago.
The problem is very easy to understand: my new ArchLinux installation can't detect /dev/sdaX where X>15.
So I can't load /dev/hda16,17,18,19.
How can I fix this?
Thanks

Re: Where are /dev/sda>15 partitions?

You might be able to get around this by using the old drivers which handled PATA drives only. To do this I think you would need to change 'pata' to 'ide' in your mkinitcpio.conf and rebuild the image. If it works correctly and goes back to using the old drivers on your next reboot all the PATA drives are going to go back to the familiar naming of /dev/hdX so make sure to edit your boot loader config and fstab before rebooting.

btw, when I say "old driver" I don't really mean that it's outdated or anything. Most distros still use it as the default.

This isn't the most ideal solution since in time everything is going to move to the new libata drivers but it might be a decent temporary fix if you can't find a real solution.

EDIT: Just came across this: http://lists.opensuse.org/opensuse/2007 … 01896.html
That was posted April 14th so my guess is you'll just have to go back to the old system for now.
