    Hello @Khurram Shahzad,

    We provide a tutorial on preparing a disk or partition at:

    Tutorial - Preparing a local disk or partition for backups

    However, troubleshooting advanced issues with mounting a drive or partition extends beyond the scope of technical support we can offer. If the information in this tutorial doesn't help, then I recommend reaching out to a qualified system administrator for assistance. We provide a list of companies offering system administration services on the link below:

    System Administration Services | cPanel Forums

    Thank you.
