Hello Guys, I was traveling home from school, about a week ago, so I detached my 40G Seagate hard disk from my desktop system, The hard disk contained some movies which i wanted my brothers to see. On getting home, my brother connected the hard disk to his PC and to my surprise, the hard disk was not detected by the BIOS, thought the harddisk was spinning all jumper settings possible was tried, and the situation was still the same. We even removed all other IDE hard drives, and left this hard disk as the only disk connected to the system, event at thsi point, the BIOS did not recognise it, so also did the OS. I thought it was a Board compatibility issue, so I decided to keep the disk until I returned to school. Now I'm in school, and I've returned the disk to it's normal position on my PC, even at that, my BIOS is no longer detecting it. I though it was a problem with the electronic interface of the Hard disk, so I got a similar harddisk, and switched their electronic boards, yet the situation was still the same. To make matters worse, my electronic board worked with the other hard disk. I have gone a step further by opening the disk compartment and switching their read heads, but now I even caused more problem because both hard drives are now in the same state - bad! Please is there hope of still recovering my data from the disk? I have over 13G of music, over 3.6G of eBooks and over 10G of Softwares! Someone please help me.
