I don't recall what 'F5' on the display means, but I'm pretty sure it's an error code. I seem to recall that the sensor on that drive used an infrared LED. There are two ways you can check if it's actually emitting (besides checking the voltage across it, of course). One is to look at it through almost any video camera/camcorder or digital camera. Such units are sensitive to IR emissions, and will show such as a bright white light in a monochrome viewfinder (I have no clue what it would look like with a color viewfinder). Second option is to pick up one of those little cards at Radio Shack that glows when exposed to IR emissions. It's billed as being a tester for TV remotes and such, but hey, IR is IR no matter how you look at it. Just my $.02 worth. Hi, John. I'm doing digital basics this quarter, and I think I've survived Boolean and Karnaugh Maps (whew!). -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
