I've pulled an old IDE hard drive from a xp computer. chuck it up in my IDE enclosure, plug it into my Windows 7 pc, and nothing. not listed in dev man, computer, or disk manager, zip. i plug the same set up into another xp computer, no prob. i need my Windows 7 pc to recognize it so i can save some info off it. i dont have continuous access to the xp pc i tried it on, so i cant use that one for the rescue. my Windows 7 pc will detect my ata/sata enclosures fine, just not this IDE one.
