I had my pc running till 1-2am as usual but today afternoon my segate 1TB[sT31000340AS] hdd was not being detected ? it was bought like 6months back. I removed all the hdd except for this, tried different power-cables and sata connectors but nothing works. The hdd is not being detected in bios. The hdd starts to spin first, i get a light jerk but after 5-10secs it shuts down or may be the speed decreases, this happens in every restart ! I don't have any idea of such issues can anyone help me with it ? I know that my model is on mass failing list of seagate flagship but when i checked my serial no. it was not on the list of failing model. I am really frustrated with this as 80-90% of hdd was loaded . 1. afaik the hdd is not really dead, this issue can be fixed or replacement is the only option ? 2. Will i loose my data ? 3. What if i wanna get back my data ? Will seagate help me ? 4. Any other opinions for this situation ??? The drive is in Warranty, Expiration 24-Oct-2013 . It had SD15 firmware, i don't really know much about hdd firmwares, can i update the firmware in such situation ?
