IF you want to buy an try a larger USB drive, I'd say make sure it's a single drive internally, and not some sort of odd hybrid or dual drive of some sort. Unless you want to set this up for recording to network storage, as it appears capable of doing that. In fact, that would by far be the best way to do it if you tend to keep stuff.Yep, and its working great
It appears that OpenVIX (my preferred image) has a default standby time of 5 minutes, enabled by default:IF anybody wants to setup a 'Standby' mode for their external USB drive they are using on the Mio for recordings, here is how you do that on NA SDGr image: Menu - Setup - System - Expert Settings - Harddisk - Hard disk setup = "Standby after" Change that setting to what you want, and SAVE it.
Your drive will sleep, and wake up as needed for a recording.
