Forget all that 5400/7200 RPM nonsense. CF cards and adapters are so cheap and readily available these days just make the swap. It will be the last thing you repair in your TAM for years to come and no sense in continuing to limp along with old/dying technology. I don't know if it's just me but all those 2.5" drives are failing on me left and right. I bought a 64GB CF card with adapter, shipped, for like 80 bucks. 

Also, thus far, CCC is the best and easiest way to clone older drives.
