Linux clears RAID information on a disk

My Notebook is Dell's Inspiron 14z, the original memory is composed of 32G solid state Drive and 512G machine hard disk. Later, I added a 256G SSD to it, installed and installed CentOS, and intend to 500G of mechanical hard disk as a data storage disk. But strangely enough, even though I could not successfully mount the 32G solid-state drive and the 512G machine hard drive, I found two inexplicable RAID array entries when I looked at the disk information using the disk utility. Then it reminds me that my notebook was originally using Intel's fast storage technology, so it was possible that the disk was hidden because of the Intel RSTe raid information. OK ~ found the reason, then began a long road to toss ....

Resolution Steps

Read RAID array device information:

sudo dmraid-r

To reset the disk:

sudo dmsetup remove_all

To deactivate a RAID array:

sudo dmraid–a No

To clear the raid information on the disk:

sudo dmraid–x

Go to the confirmation where you remember to play Yes

OK, after executing the above command, you can normally mount the partition of the disk ~
