    Hi Robert,

    Weird - that's what works for me, so I don't know how much more help I can
    offer, but here are a few suggestions that might help us figure out what's
    going on...

    Ah... you're running FreeBSD 5 - it was pretty late when I wrote that first
    reply, so I didn't notice that immediately. Unlike FreeBSD 4, where stuff
    in /dev/ had to be created manually, FreeBSD 5 uses devfs to create the
    device nodes as needed, when devices come and go. I haven't actually used
    my card reader on 5 yet, so I could be missing something obvious here...

    What does 'fdisk da2' give you at this point?
    Do you get anything in /var/log/messages when you insert the new card?

    It might be worth doing a 'camcontrol start' after the rescan, just in
    case, but I don't really think that will make any difference.

    Since you're running FreeBSD 5, it might be worth re-porting your question
    to the freebsd-current mailing list, to see if anyone there can shed some
    light on this.

    Sorry I can't be more help,

    Scott

    Aloha and mahalo Scott
    I had tried the "camcontrol start" before but I tried again without any good stuff.
    Fdisk seems to show the correct readings but I could use some help interpreting
    the output of "/var/log/messages".
     
    I am traveling now so I am using my laptop which is running current. When I return
    to Kona (7-6) I will try on one of my desktops that are running 5.2.1

    Thanks again for helping.
    Robert
