Installation

I'm in the process of upgrading my m0n0wall router with all new hardware.  The previous system had been running on a compact flash drive (actually 3 over the past 3 years), and now I'm attempting to go to a different flash drive,  from Transcend. http://www.transcendusa.com/products/ModDetail.asp?ModNo=26&LangNo=0

I have attempted to load m0n0wall on the drive a few times now, using Windows and Ubuntu.  In Windows, the physdiskwrite program doesn't even see the drive (which appears as a hard drive in Windows).  In Ubuntu, I run the gunzip command and get the following:

dd: opening `/dev/sdb': Permission denied

I've tried this command multiple ways, mounted and unmounted and I still have the same problem.  Anyone have any ideas on how to get Ubuntu to allow me to write to this drive?

While the problem with Linux still exists.  I figured out why Windows didn't cooperate.  Having used XP the past 3 years to configure m0n0wall, I hadn't configured it using Vista.  All is up and running now. Still confused by Linux and it's issue, but at this point, I just don't really care.

.........dd: opening `/dev/sdb': Permission denied......

You must be a root(sudo su....su root.........)

I get the same error, even using sudo. Is there another error in the following command?

Code:

sudo gunzip -c generic-pc-1.235.img | dd of=/dev/sdb bs=16k

Doesn't sudo only affect the first command?  I'd run it in a sub-shell by using quotes, e.g.,

Code:

sudo "gunzip -c generic-pc-1.235.img | dd of=/dev/sdb bs=16k"

Or perhaps better a double sudo

Code:

sudo gunzip -c generic-pc-1.235.img | sudo dd of=/dev/sdb bs=16k

Of course one could always just run as root but it is a practice to be discouraged.
