    How can I restore the missing /dev/hdb1 & 2
    entries(links?)?

    I've been using a 9.2 Pro box for going through a stack of
    older hard disks with various partition arrangements
    without using YaST to mount them. I also have been using
    external USB and Firewire drives as backups for various
    machines as a test.

    I connected the external drives at various times with hdb
    installed as well as when hdb was not installed. I just
    tried a drive as hdb and had trouble using mount to a /mnt
    directory and it says that hdb can't be mounted and is a
    'special'(?) drive.

    I checked fdisk -l /dev/hdb and it shows all the LINUX
    types in the listing. I tried YaST's partitioner and while
    the partitions are shown I can not assign mount points.

    /sys/block/hdb exists as does /dev/hdb but /dev/hdb1 & 2,
    both primary partitions are missing. /dev/hdb5 inside an
    extended partition can be mounted as normal.

    It could be that udev is working and something is wrong
    with hdb1 & 2 but I tried Knoppix and I have no trouble
    mounting all three.

    I've gotten a feeling that the hotplugging may have done
    something. I did try the same drive in the external USB
    and Firewire cases and I noticed a long list of drives in
    /dev/disk/by-id which appear to be the IDE drives. In
    /dev/by-path I see what appears to be the external drives
    even though they are not attached.

    Can I just erase the contents of /dev and have them created
    at startup? Is that a really bad idea?
