[IDEA] Create/protect music partition on SD card

[Miss Sissy Princess]

One of the challenges with generating interest in the proposal though is that modern USB storage is fast, compact, super reliable and cheap for example this 512MB device...

That's a very good option and one I will consider.  It's the same form factor as the USB "thumb" drive I use as my Unraid OS drive.

I kind of like the idea of having the USB dedicated solely to my USB DAC.  Right now, I have a 512GB USB SSD on one of the USB 3.0 ports and I have the Emotiva USB DAC on one of the two USB 2.0 ports, but all of the USB ports go through the same VL805 chip.  At least it's not like prior Pi boards where the Ethernet was, in essence, another USB device.

Thanks for suggesting that fits-in-the-pocket alternative.
