GRUB counts hard drives, doesn't care where they're attached, it only counts the hard drives, skipping other drives. e.g. Port Connected Older Linux Grub ----------------------------------------------- IDE1 primary HDD /dev/hda hd0 IDE1 secondary nothing /dev/hdb IDE2 primary CD-ROM /dev/hdc IDE2 secondary Zip drive /dev/hdd IDE3 primary HDD /dev/hde hd1 IDE3 secondary HDD /dev/hdf hd2 I've picked on the older Linux scheme of absolutely referencing drives, being something that many of us are very familiar with, and to show what consistency versus inconsistency does for getting predictable results. I haven't worked out how the new /dev/sdx scheme will work, but I suspect you'd see this sort of thing: Port Connected Older Linux --------------------------------------- IDE1 primary HDD /dev/sda IDE1 secondary nothing IDE2 primary CD-ROM /dev/sdb IDE2 secondary Zip drive /dev/sdc IDE3 primary HDD /dev/sdd IDE3 secondary HDD /dev/sde And, if you plugged in an external USB drive, and *if* your BIOS will use USB first when there's something on it, you could expect them all to shift to higher letters, with your USB drive being /dev/sda. -- [tim@bigblack ~]$ uname -ipr 2.6.22.9-91.fc7 i686 i386 Using FC 4, 5, 6 & 7, plus CentOS 5.
