It might be possible that the names sda to sdd were used for something
that wasn't an hard disk during the install (a card reader with 4
different slots might be a good candidate). Then your system would
still boot properly with your old device.map because grub detected
that sde was the first hard disk, but then you wouldn't be able to
run update-grub because your first hard disk is sda now. Could you
check this in the installation log or by running the debian installer
again to the point where it detects all the disks?
