Hey everyone and thanks for stopping by, Have to say I joined this forum community specifically for this issue and searched the forums for similar problems relating to mine but then again each one is unique to it's own system so I’ll stop rambling now My pc (see profile for details or feel free to ask) was running fine a few hours ago then I tried a (gigabyte) bios update, which I thought was fine but during updating it froze so I had to terminate the program then restart. Once that happened the bios didn't come up at all and needed to restart again but luckily this motherboard is equipped with backup bios I think... anyway it came up again and that leads to my problem. My slave drive can't be detected! Both drives (160g) run on sata cables. I checked the bios settings to the best of my limited knowledge and didn't get far. Cables are all fine; device manager doesn't detect my secondary hard drive even after much uninstalling.reinstalling..Updating. ect. I’d very much appreciate any feedback as all of my applications are on the "undetectable" hdd, which I need fairly urgently, Thanks in advance Aussie.
