我岩岩買左個external hard drive
終於可以backup晒0的野再format啦
但係我想問下點先可以101%大清洗？(因為有勁virus同spyware)
我部laptop係dell，佢有隻cd比我，係recovery？？
用呢隻野再install過windows得唔得？

dell 應該跟2隻cd, 一隻係driver, 另一隻係windows.

可以的話最好當然係reformat啦, 但如果唔可以reformat的話, 咁要睇妳部機有幾嚴重啦!

點reformat呀？
放隻windows碟入去就得？
洗唔洗format晒2個drive呀？

定係咁就得？

嘈嘈, 唔好意思呀, 我依家先睇到妳呢個post咋!! 係呀, 放隻windows碟boot機時勁按"enter"至出現loading windows 咁上下的字, 然後跟指示做啦! format 2 個drive係最好的做法!

There are lots of third party utililties software which can help you reformat the HDD.  However, if you know the brand of your HDD, it would be easier to go to the official website and get some sort of harddisk tools to help you out.  For example, Seagate has an official site and you can download the Seagate Seatools free of charge and this software fill your HDD with zero.  That means it is completely cleaned.  You can find others from the web too.  Good luck!
