Yeah, I'll be careful!
Code:
I ran the mtab thing and have this:
/dev/sdb /media/READER vfat rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush 0 0
/dev/sde /media/LAUNCHER vfat ro,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,flush 0 0
Looks like sdb is, indeed, what Ubuntu labels it as.
Launcher is the Sony software that comes with the device.
It always gets mounted, too. Don't think there is a way to get rid of it.
Anyway, thanks for you help. Looks I'm good to go now!
