Sorry if I wasn't clear.

I think both the PARIDE and UDF systems are working fine on their own. ( pcd and pg both recognise the drive fine, and udf is an installed filesystem )

The problem is that the design of the two seems incompatible, pg is a character device while udf requires mount, which wants a block device.

I was thinking that I can't be the first person to try to do this (I did look through the mailing list archives but couldn't find anything about it though), so I wanted to ask for advice from anyone who had been in a similar situation.

Does anyone know of a way to resolve this problem, either by creating a block-device version of pg, modification to pcd (which is a block device), or modification to udf or mount to trick them into working on a character device?
