Sony VAIO SVE151J11L BIOS is not detecting my HDD (showing operating system not found) and i tried connecting it to other computer with SATA External Case without any luck. Hard disk is running its not dead. Please help if i can fix it. I have Imp data in it. Will i be able to recover? Thank you.

IF the bios is not seeing your HDD. You cannot use any recovery software. It’s a faulty HDD. You can buy hardware like rapidspar but its very expensive. I think you best change is to send it to HDD recovery firm
