I currently have 4 devices in my IDE slots: 1 x Maxtor 80gb (primary master & the one Windows is installed on) 1 x WD Caviar 120gb (primary slave - storage nr1) 1 x NEC DVD-RW (secondary master) 1 x WD 250gb (secondary slave - storage nr2) Now, for about a year it's been running fine. Then, all of a sudden storage nr2 stops appearing. Reboot and it hangs at the BIOS startup screen, and storage nr2 isn't in there either. Since that happened out of the blue, if I have the primary one plugged in - which it needs to be, as it has Windows installed - storage nr2 won't show up anywhere and the BIOS always hangs no matter what the configuration of the other devices; I can unplug everything except that hard drive and it'll hang. Again that's just started randomly. If I unplug that drive then storage nr2 appears in the BIOS, and it doesn't hang! What's going on?!
