I don't know how well they work, but there are converters so you can use a SATA drive on an IDE port; and compact flash to IDE is just pin mapping. Either option seems like a better idea than hoping 10+ year old drives keep going. Depends on how historically accurate you want though, I guess.
You can still get refurb or NoS IDE drives that have good reliability. I don't recommend SATA to IDE adapters because they're known to cause massive data corruption, don't always work and are expensive. CF or SD to IDE is a viable option, but flash media is expensive and older OSes don't know what flash is and tends to destroy it.
