Dave: thanks for the quick reply.
It is unlikely the Gparted to be blamed. After it shrank the disk, I was able to boot back into Macintosh HD and run disk util to format the new Sandbox into HFS+, and it is not just files being hided, the two volumes lost bootable flag.

One abnorm thing during Sandbox creating: the On succesful completion option list has Restart from Sandbox, Set Sandbox as Startup Disk two items grayed-out. Any clue?
It seems, I have to use Disk util to fix the Macintosh HD first and restore the OS. Thanks to SD! user manual's emphosizing backup first before doing anything, I still have an OS to go.
