I see.You mean use an IDE hard drive with something that expects a CF card? I think it may be possible. There's an adapter to use mSATA SSDs with cameras that use CFast cards, i.e. CF's successor, so the idea isn't new.
CF to 40pin (desktop) IDE adapters have a power connector (often 3.5" floppy drive style) on them.
CF to 44pin (laptop) IDE adapters don't because the power is coming from those four extra pins.
My only wish is that cf cards get back into production more, because currently there's a shortage at best buy. They had to special order me some and they could only find like 3 to stock.
Manufacturers, get on it! With 1, even 2 TB usb drives and 1 TB micro sd cards, all without using msata or m.2, purely what they can cram on board, a cf card could be bonkers now. Sure it wouldn't be that fast, but if we can fit 1 to 2 TB (for real, Kingston and Patriot have) on a usb and 1 TB on a micro SD, we could fit like 4 TB in a CF, and tons of machines already have CF ports.
I can't think of many good reasons future portable drives shouldn't be in CF form other than the IDE bus! Plus it'd make small CF card prices go way down!
