Should I be worried? (usb)

[NotsogoodwithPCs]

So I was told to transfer my windows 8.1 onto a usb because I recently ordered a new motherboard and that would obviously save me money from buying a new OS.

Well I did everything that I was told to do, followed the procedure via Microsoft website and everything downloaded smoothly onto my usb, but as I tried ejecting my USB later on in the night it was saying it was being and couldn't safely eject. I tried to figure out what it was before ultimately just ejecting it myself and now I'm worried that I might've corrupted the files or something even though yes Windows 8.1 had finished installing hours ago on it.

Should I be concerned or am I over thinking it? I was about to go to the lengths of deleting the files on it but I've heard its a rather annoying process to FULLY wipe the USB. Thoughts? :/

It is said to be recommended to let Windows know when ejecting usb sticks but i never do, long as there's no activity coming from it like copying files or installing something from it, nothing has ever corrupted on me. Since Windows was installed already after lengthy amount of time i wouldn't worry about it.

If it happens again to another usb stick and want to make sure just restart the pc and pull it out while its booting.
