Windows Shows error "Can not format the pen drive" ?

We have received many problems mentioning that they are not able to format their pen drives. Some of them have written that the pen drive capacity displayed is not correct.

When they try to format the pen drive, Windows Shows error "Can not format the pen drive". There can be more than one reasons behind such problems, some of the common problems are:

1. Virus or trojan infection.

2. Corrupted flash chips on the pen drive (hardware fault)

3. Fake pen drives ! (Many such drives are there in the markets, beware)

Lets see what to do to fix the issues.

Fix:

Virus or trojan infections:

Virus or trojans can run some process that keeps running in background. This not only harms the computer, but also prevents the pen drive from formatting as it shows that the drive is in use. Remove and re-insert the pen drive, don’t double click on drive and cancel autorun operations if it starts automatically. Run a virus scan on pen drive, this will help fix the issue. Now format the pen drive.

Always take precautions while using pen drives on other computers.
