Removable USB stick listed as non-removable in /sys/block?

In my question https://unix.stackexchange.com/q/119243 I got stuck on a problem nobody else seems to be having. (The issue also impedes my desire to use this answer .) So I made that specific problem into this new question. Apparently removable devices listed in /sys/block end with 1. It is stated here and several other places in this site and this principle is used in the answers I referenced above. My removable device, a Sandisk 64GB flash memory stick, is listed as: /sys/block/sdl/removable:0 Apparently, removable devices should end in 1 (and my others do). Why does my USB memory stick not follow the rule? It was automounted by Dolphin. I'm running Kubuntu 12.04. Dolphin shows it as "59.6GiB Removable Media". And it is mounted (automatically) at /media/me/70E8-1567 sudo blkid shows it as: /dev/sdl1: UUID="70E8-1567" TYPE="vfat". lsblk -do name,rm shows: sdl 0 And lsusb -vv shows: Bus 001 Device 008: ID 0781:5530 SanDisk Corp.
