The problem: Virtual disk service error clean is not allowed

I have a Windows 8.1 Lenovo Yoga 13 with 128GB hard drive, and I bought an identical 128GB SSD from eBay, which comes with a Windows 8.1 installed and all the partitions. But I want to use it as my secondary storage device and delete everything on the new SSD. But I can’t delete the partition on the new SSD via Disk Management. Then I used diskpart clean command to clean the new SSD drive, I get an error message: virtual disk service error: clean is not allowed on the disk containing the current boot, system, pagefile, crashdump or hibernation volume. I’m not using it as my system disk, why I can’t clean it at all? Can anyone help? Thanks.
