Hardware, Embedded Systems Current computers use SATA disk drives. Pentium IV's and earlier computers used the IDE drive standards. How can you intermix SATA and IDE disk drives? This article discusses the options. It is the next in my series of articles on computer refurbishing.

To benali72 and Laurence, I don't believe faulty hardware is the problem.The devices work.perfectly well IF A DRIVE IS PLUGGED IN. The failure condition is only when the system tries to boot with card / adapter powered and plugged in but with no drive attached. In the case of the PCI card by Ultra, tech support actually told me there was no way to make it work. It appears that the devices are not designed to deal with the scenario of booting without a drive connected. Before you say, "Why would anyone ever do such a stupid thing," believe me that I have a valid, reasonably frequent scenario where I normally boot without a drive but every once in a while boot from a PATA drive. It's in a business environment involving old but still-running machines using the QNX RTOS.

Thanks,
James

Oh, I understand the problem now. Thanks for your elaboration.

Yes, I can tell you the drive dongle products (like the Syba) aren't designed to work without a drive present. When you boot it does its initialization, and if there is no drive present it won't work.

The main thing I can think to do would be to try the USB approach the article outlines. That way you could add or remove the drive at will, since it's external. I don't know whether it would address your needs but it would work and it would give the flexibility to easily add or remove the drive. Just plug/unplug the drive into the USB connector prior to each boot.

If you use this approach on a regular basis you'll want to buy a drive enclosure for the external drive too (most the USB products exclude that part).

Best of luck.

BTW-- I used to love QNX.
