I accidentally touch the data cable on data transfer, and the computer froze. When restarting the computer I see in the Disk Manager say my HDD is in RAW format. I format it but I say Windows is unable to complete the format, I think after that my HDD is very unstable and randomly disconnects from my pc(I replaced my cable but can't fix it). I search on google "how to fix bad sector on HDD", and some sites recommend using Disk Genius. At first, It appear a bit bad sector but after scanning and fixing it fills the screen with a bad sector. But the HDD is surprisingly quiet I can hear it spinning and some click when I get very close to it. I now make the software up and running full day to scan and fix the bad sector. my HDD is WD brand, it model is "wd1600bevt"
