When you open a new topic, there is a template by default. It helps you to provide enough information for others to help you. In your case, you need to find out if this is a NC-specific problem (configuration, the way you added the drive etc.), an issue with the disk, or something with the system (how you added the drive), or perhaps something different. If you checked the disk before on a different computer, and it was fast and reliable, we could exclude the disk problem.
