Cannot mount pendrive

[Mariano Aliaga]

Hi,
   I tried to mount my pendrive today on 1.10.1 (installed from ISO)
with no luck. When I try to mount it with:

   mount_msdos /dev/da0s1 /mnt

I get "mount_msdos: /dev/da0s1: Invalid argument". I tried then to
list the disklabel with:

   disklabel da0s1

and got:

   disklabel: ioctl DIOCGDINFO32: label magic number or checksum is wrong!
   (disklabel or kernel is out of date?)

dmesg shows the following:

da0 at umass-sim0 bus 0 target 0 lun 0

I tried also with 1.8.2 with the same results. What am I doing wrong?

Thanks in advance
