Thanks everyone for the replies, I really appreciate it.
The card is a 64GB Sandisk Ultra Class 10 (Transfer speeds up to 30 MB/s). The latest episode occurred when I put almost 10GB of music on it, 3GB or so of hi-res. I've done a factory reset but haven't reloaded the firmware.

I don't do any tagging. Can anything be done about the file names/tags issue?
It certainly does get stuck, even when I first turn it on when making no file changes.
Even when the scanning message isn't displayed, at times on the Advanced Mode screen the 'All Music' and 'Now Playing List' don't respond at all. Or the timing fields on the Basic Mode screen are all zeros and pressing the Home button doesn't bring up the Advanced Mode screen (like now). I can navigate by going to the second screen and selecting a category like Albums but this is a flat list and a pain to use. Eventually it usually rights itself, other times I turn it off/on and/or do a reset.
It's too bad the X3 only takes 64MB cards, I picked up one for a friend and loaded it with 50GB or so of music and was able to navigate and play what ever I wanted immediately.
