I have a pen drive. Usually there is no problem when I plug it in. But now a new hard drive is appearing on my with the name “System Reserved (Z:)” and it’s empty of files but shows that 70.3MB is free of 99.9 MB.
After this happened, my Windows OS began to give me an error that says a change has occurred to the system and I need to reinstall Windows. Is this related to the mysterious hard drive? How can I resolve this?
