How format USB drives that cannot be formatted ?

Today there are a lot of of viruses that corrupts flash drives thus making them unusable.

If you've got a flash drive which you cannot format using the default windows format utility , i suggest you to use a program called HP USB Disk Storage Format Tool
which i found very useful in saving my 16 GB flash drive from corrupting. Already a folder in my flash drive with very important documents have corrupted.
