Format

Some require that you use the makers Utility to format as they use compression to get the capacity where as others just require that you enter Disc Management in Windows to format.

However as you asked about [i]i put password for my pendrive.[/i] I'm assuming that you mean Encrypt not format.

Again this depends on the Maker & it's Model some Thumb Drives have this from new and you can change the Password from the Default to your own or leave things as they are.

If your Thumb Drive doesn't support this you'll need some form of Encryption Program so try looking here

Just remove the space from between the Domain Name and the [i].com[/i] to get a working URL. ;)
