Subject: Re: USB Mass Storage devices
First, look at dmesg to be sure it's getting assigned to /dev/sda (it most
likely is if there's no other scsi drives in the system). Assuming it's
there, try doing "fdisk -l /dev/sda", and then mount it. I haven't yet
figured out why the 2.6 kernel often doesn't detect the media on it's own
like 2.4 did, but running fdisk -l forces it to scan the device. I'm sure
there's a far more graceful solution, but I haven't bothered looking for
it yet. (-=
