After formatting my passport ultra with windows

I understand formatting my passport drives get rid of all of the contents in the drive. But does it get rid of the factory softwares as well? If so, do I have to reinstall it?

Problem found:

After formatting my passport ultra, the transfer speed decreased a lot. Its so slow now I dont understand why.

It used to be: around 40-75 (3.0)

but not its: around 15-22 (3.0)

Much help is appreciated. Thx guys

Try and reboot?
