I have a Linkstation Quad LS-QLrunning Firmware 1.05
I can disable the Recycle Bin / trashbox for each share through the web interface. This settings takes effect immediately, and the trashbox disappears and the Recycle Bin option for that share stays disabled.
However, when I change the user settings / group membership, the Recycle Bin is enabled for all my shares.
Has anybody else experienced this issue?
