Hi, I have an ASUS P5B Deluxe motherboard, a SATA HD and a SATA optical drive. Until today, all was working as it should. I tried to rescue data off an IDE HD by adding it as a second drive. This failed miserably for reasons I'm still not sure of. I could less about that now, however. Once I gave up on the IDE drive, and disconnected it from the system, I get the POST message "Detect Drives Done, No Any Drives Found". Not the SATA HD, not the SATA optical. This means I can't boot up period. I've tried reflashing the BIOS, playing around with the BIOS settings, but all to no avail. The weirdest thing is that the BIOS lists both drives and correctly identifies which port they are plugged into. I don't get it. Anybody out there with some idea?
