I was trying to share the data on my removable (ext3) sd card with my computer; in other words, I wanted to be able to read and write to the same files on the sd card from either the tablet or the computer. The problem is with the permissions: files get created with the user "user" on the tablet, and with the user "belanger" on my computer, and that causes problems. Is there some way to get the tablet to use uid and gid 1000? (I think that would take care of the problem. Or is there another workaround?)
