I have an acer laptop with a problematic disk, it didnt want to boot up but when i booted to usb and checked disk manager it said that the disk is basic and online but the whole disk is unallocated with and asterisk on where the drive letter shoud be. I used aomei disk manager to have a disk surface test... only 2 red squares and 32 bad sectors, rest is fine. The last time I saw the volumes, it hade a recovery,system,data, and another one, but the data volume was a healthy raw. Please help thanks
