I've been having this problem for a few months now. When the computer wakes from a sleep or hibernate state, my data drive (a 1TB Samsung Spinppoint) occasionally fails to come back with it, and the operating system no longer recognises that it even exists. This only happens when the drive is run in AHCI mode. If I switch it to IDE mode the problem goes away. It's easily fixed with a reboot, but it's becoming a pain. My system drive is a Samsung Spinpoint 500Gb running in AHCI mode, which never experiences this fault.
Initially I believed there was something wrong with my motherboard, which had already been diagnosed as faulty, but the problem continued after the MB was changed. This has now happened under three separate configurations:
ASUS P5K Premium WiFi motherboard with Vista (64-bit)
Gigabyte P35 DS3R motherboard with (Vista 64-bit)
Gigabyte P35 DS3R motherboard with Windows 7 (64-bit)
Otherwise, the disk works perfectly, and diagnostics reveal no problem.
Any suggestions gratefully received.
