My less than two years old laptop's hard disk (Toshiba 500GB) abruptly died today. There were no issues until windows hanged and I had to restart. The booting hanged at "starting windows". Since then, the booting hangs at bios screen. The hard disk is being detected in the bios prompt correctly. Do I need to replace my HDD or is there any chance of repairing it? And any chance of data recovery?
