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
