I've never seen an IDE drive with any *options* for controlling termination. Keyword being *options* (as in something that you control). I won't argue that they don't need termination, but I'll say that it's not an option, the drives and hosts are designed with what they need as-is. Which goes some way to explaining why you can't use long cables, you can't terminate drives optimally for how you've cabled them (one or two drives), what they have has to work whether there's an extra drive in the middle of the cable or not. Ages ago I waded through the specs IDE/ATA, whatever you want to call it, and don't recall user-configurable termination being discussed, either. -- Don't send private replies to my address, the mailbox is ignored.
