In addition to the comments from Mary about partition UUID's I think you will find the reason that drives are re-designated as hdxx when adding SATA to the mix is a BIOS thing. I'm sure you will find a section in your BIOS setup that controls SATA/PATA emulation modes.

Ideally the system should be using drive UUIDs to identify partitions now rather than the dsXX and hdXX identifiers although I think in some circumstances one might not be able to. Does /etc/fstab look like this: UUID=b6c863a3-f68c-4b7f-a7b7-07e19d671903 /home ext3 defaults,errors=remount-ro 0 1 or like this:' /dev/sda3 /home ext3 defaults,errors=remount-ro 0 1 Does /boot/grub/menu.1st have a line like this: kopt=root=UUID=b6c863a3-f68c-4b7f-a7b7-07e19d671903 resume=UUID=0d6f4ee5-c312-42b1-a543-5f0f9f040eff ro or does it use /dev/[hs]dXX? (Or do you not use grub?) The idea of the UUID= identifiers for partitions rather than the dsXX and hdXX identifiers is that they should only change after a reformat, not when the kernel the way it addresses them. You can find out a partition's UUID with the "vol_id -u [partition]" command, eg: $ sudo vol_id -u /dev/sda3 b6c863a3-f68c-4b7f-a7b7-07e19d671903 There is more info at https://help.ubuntu.com/community/UsingUUID -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
