Hello, My external hard disk has been acting up i.e it would take time to load some documents. So I decided to perform the Check disk options. This has been going on for the last 3 days and am thinking of cancelling the process because it seems to be stuck and it is not even 20% done. What will be the consequences of cancelling it?
