Looking for SMD drives (specific models)

So I had the Ridge 32 running again (when I went to debug the -12V supply it had started working again, so I'll take that for now, I suppose). After running for an hour the SMD drive (a Fujitsu 2312) in it failed. At power up, the drive spins up and when it attempts to load the heads, there's a loud *clunk* and the drive then quickly spins down. (If anyone has any bright ideas, let me know...) I have a few other SMD drives (just picked 'em up today, in fact) but they're newer (~825mb) and the Ridge disc utilities only support a small subset of drives (they do not support providing custom geometries, because that would be *too easy*.) Here are the disks it lists as supported; some of these are pretty insane (CDC 9762? Really? Not sure about the Pertecs either...) but the Fujitsu's aren't entirely out of the question: Fujitsu: 2351A (Eagle, don't I wish) 2322 2333 2312 2344 Priam: 806 807 Pertec: DX 300 DX 332 DX 548 DX 199 DX 265 DX 365 CDC: 9766 9762 Anyone have one of the above they'd be willing to sell/trade/etc? Thanks as always, Josh
