I gave it a try. Now booting up at 7-10 and inserting the hard disk DSM does not recognize it, and there is no response.
DSM can recognize USB external storage now. 

The DSM version is DSM 7.1.1-42962 Update 2.
I remember before the 7-10 when the hard drive was not plugged in, the USB external storage was normal.
I don't know how to select and delete.
I gave it a try. DSM is still recognized as a local disk even if the USB external storage device is inserted. 
If I change the SataPortMap to 49, will it work?
