Bad Sector Kya Hota Hai?
Hard Disk kai chhote-chhote sectors mein vibhajit hoti hai jahan data store hota hai. Bad Sector wo sector hota hai jahan data theek se read ya write nahi ho sakta - woh sector kharab ho jaata hai.
Do tarah ke Bad Sectors hote hain:
Logical Bad Sector: Yeh software-related problem hai - aksar virus, sudden power cut, ya improper shutdown ki wajah se hota hai. Inhe chkdsk tool se repair kiya ja sakta hai.
Physical Bad Sector: Yeh hardware damage hai - disk ka actual magnetic surface kharab ho jaata hai. Inhe fix nahi kiya ja sakta, sirf mark karke bypass kiya jaata hai.
