Right you are, but only $15 on eBay . The circuitry to convert the 40-pin
IDE data to USB is built into the HD connector itself. Several VLSI chips that
I can see.

Well, I will have several Seagate IDE drives (only one now) mounted in a
homebrew external case I made and would like to know when it/they are active.

The Power LED is simple, but data is another matter
