ကၽြန္ေတာ့္ Memory stick က Kingston 2G ပါ Virus က Folder ေတြကို .exe
နာမည္ေတြေၿပာင္းေၿပာင္းလိုက္လို႔ Format ခ်တာ
"windows cannot format this drive.Quit any disk utilities or other programs that are using this drive, and make sure that no window is displaying the contents of the drive.Then try formatting again."
ဆိုၿပီးစာတန္းပဲတက္တက္ေနတာ Format လံုး၀ခ်လို႔မ၇ဘူးၿဖစ္ေနလို႔ အႀကံဥာဏ္ေလးမ်ား
ေပးၾကပါဦးေနာ္...

For window XP,
Go to start then run, type cmd
enter

In command prompt(cmd.exe) type this

format/q/x :(your drive letter)

i assume your pendrive is f, if not, change the drive.
if this message occur as bellow
The type of file system is raw. Please use the /FS switch to specify the file system you wish to use on this volume

so you type this
format f:/fs:fat32

Most memory stick use file system fat32

Then, your problem will be solved

Be happy!
