Hello guys. Few days ago when I turned on my pc(after 2-3 hours),the hard disk was not detected. I tried it elswhere but I encountered same problem.I also changed my IDE connectors but also of no use. My hard disk was samsung 40gb SV0412H (3600RPM) I have an P3 1000MHZ &ASUS MOTHERBOARD. What can be the problem ? How can I recover my data? Is it of no use now?
