Anyone using a 4200 drive for DV work?

In theory, there's no reason such a drive cannot work for DV transfers. Your drive must support a sustained data transfer rate of 3.7 MB/s and almost any drive out there will do that. (Most current drive perform at well over 30 MB/s.) If you can, you may want to test this with the specific system in question. With this being at the slow end of the curve these days, it wouldn't hurt to make sure it will work before laying down the cash.
Probably the worst thing about this setup is that you'll probably be using the same disk for your system as for your capture. That's not to say this cannot work, but it's one of the areas that often cause trouble for people. Ideally, you would want two IDE channels with one drive on each, one the system drive and one the capture drive. Some people say they use one drive without problems and so it's certainly possible, but some people also have problems that seem to be solved by rearranging their systems that way.
Good luck whatever you decide.
