Asslam O Alaikum Dosto.

Dosto main apny system ki hard disk change karna chahta hoon. Main chahta hoon k apni mojooda hard disk ka tamaam data format kar k is hard disk ko sale kar doon. Kiya aisa mumkin hai k is hard disk k ko kisi aisay software sey format kiya jaye k hard drive k data ko koi recover na kar sakay. Mera matlab ye hai k formated data kisi bhi software k through recover na ho aur permanent delete ho jaye.
Ap ki rehnuamai ki ashad zarrorat hai.
Ap sab ka bohut shukriya.
Allah hafiz
