I unplugged to soon and erased everything and now when it turns on it give me a file system fail error and then it goes to wait for usb connection and just stays there

the scan is just a program reading the files and folders either in the computer or storage device
normally it is done by the security program ( windows fire wall) or what ever program you have installed
it reports on any problems found and waits for your decision
if you run a system check, that is different as it will rectify any program faults as it goes not files or folders
it is always advisable to scan usb sticks when installing as that is a favourite way that hackers get into a computer
although the usb stick may be in your control all the time , downloads from your own computer can transfer a problem via usb stick
As for your concern---scanning will not change any files or folders but will report on any faults to you

From what I can find, it would seem your Xbox one is having trouble connecting to the Microsoft servers. It could be because of increased traffic, or an issue with your internet speeds.It is also possible, that the services provided by Microsoft, are not ready yet. It happens a lot during the first while of release of a new system.The PS4 is having simmelar issues.

This happens when you connect your camero to your PC. Try plugging into another usb port if doesnt work Uninstall the Canon Software on your PC unplug the camera then restart your PC. When the PC is ready then plug in your camera to the PC. Wait until you see the Removable Icon on the System Tray. Now go to My Computer then check if you will be able to access your files. If everything fails try to use a card reader

Thanks for using Fixya

yes...unplug from pc shut mp3 off for a minute...plug it to pc (did it come on turn it on)...please get into the habit of disconnecting any usb connection with the safety disconnect...(green icon in task bar when usb is connected)...since you already deleted all files (format it now) start fresh...now you are able to put your songs on it...but to disconnect do not....do not just unplug the usb
