So yesterday my brother dropped my acer travelmate 4740 and since then it wont boot. Although i am able to boot into ubuntu using live usb but when i try to mount my hdd into ubuntu, it wont mount. I'v also tried using windows system repair but it doesnt work either. I think im looking at a faulty HDD. In ubuntu to it says the drive works OK with 47 bad sectors. I don't know what to do. Please help...
