USB to IDE adapter

Is CF suitably low pinout?
No, I had thought of that. I only have 12 pins maximum. I forgot to mention also that we have strict electromagnetic emission requirements (it's for a military device), so it has to be a balanced serial bus - it can't be parallel or an unbalanced serial bus. Thanks anyway

My goodness, long time no post... I'm looking for some type of adapter to allow me to plug a USB thumb drive into an IDE port. Can anyone tell me if such a thing exists? I haven't found one so far, but searching for anything with both USB and IDE in the search phrase turns up a whole heap of external hard drive enclosures and that's about it. I want to go the other way. If anyone's interested, it's for a Windows XP embedded system that is required to have a removable hard disk on a low-pin-count connector, hence USB. Unfortunately, SATA is not an option. We have encountered a problem where if any USB device is unplugged, Windows appears to re-enumerate the entire USB tree (regardless of which root hub the device was plugged into), which causes BSODs if Windows is attempting to access the USB drive (which is the boot drive) at the same time. So we're trying to keep the USB interface to the disk, but make it look like something else to the OS.

Oh you are still alive? damn what happened to you dude? Sometimes I wondered what could have happened to someone called Ryan and who used to crack some well-timed jokes.. lol good to see you back. welcome. But unfortunately I'm not finding enough time to peek into CP these days..I'm just batch processing all the messages in weekends. Anyway how are ya?

I think so. Most days, anyway. I've just finished a 55hr work week, so I'm intending to take it easy this weekend. I'm well, but very, very busy these days. There's this really inconvenient thing called "work" that seems to consume most of my day :)

Addonics do them.
Visit http://www.notreadytogiveup.com/[^] and do something special today.

Are you sure? I just spent about 30mins searching their website, and all I could find were adapters that go the opposite way to what I'm looking for.

How many pins does the round esata power connector have? IIRC it's 5 or 6, the former would keep your pincount within spec.

We've tried SATA previously, but due to a few issues (such the number of connectors and the length of the cable causing signal degradation and unreliability), SATA just didn't work well enough. USB works beautifully until we disconnect another USB device while Windows is accessing the USB drive. Either we need to find some way of making the USB drive look like SATA or IDE to the computer, or convince Windows to never re-enumerate the USB drive and assume it always exists. I'm not sure if either one is possible.

Very late reply, but I just came across the adaptor today. Would using SD via SD-CF and CF-SATA adaptors be permisible. http://www.dooyoo.co.uk/other-memory-adapters/minolta-sd-cf1-compactflash-card-adapter/[^] Alternately what about removable SATA? There are only 7 data lines, and the power cable only has 5 wires internally. It might require a custom enclosure, but the commercial ones I've seen would never survive MS-810E testing anyway.

Thanks for the reply! Unfortunately, we've had no success with SATA due to the length of the cable, the number of connectors involved, and the fact that we can't use proper SATA cable. We are using waterproof connectors that come with wires already attached and waterproofed - and they're not twisted pair. USB seems to work, but SATA did not at all. We have a workaround - it's not pretty but it will do.
