Thanks Matt, but it's not related to one song, and I've been using the Audiophile versions for years. As far as I know, it's using the Wave files on the PG-supplied drive.

One possible difference in how I've been using it lately is that before, I was using it for standards, thus pretty much exclusively using Real Tracks. Lately, I've just thrown together mixed styles to get a rough mix of whatever old rock song as a practice tool, and it seems maybe(?) it's crashed more often (but not exclusively) when hitting the disk building a style from the Stylepicker.

Also, another thing comes to mind. A couple of times in the last few months I've had a "Current drum kit has no bass, snare, closed hi-hat, open hi hat," error. I posted about that, and Jim Fogle suggested I return to factory settings, which I'd done; however, I'd not done the full return to all factory settings. Did that, and that fixed the problem. And now that I think about it, I had to do that again last week.
