Motorola Droid 4 - Mystery /data partition 3gb

[CATMAN8]

Hello,
Recently a strange partition (storage area?) Appeared on my phone. it is simply called 'data' and it would seem my phone has set this as the new default app installation area. it's 3gb in size..
When I plug it into the computer, The other storage (internal and sd card) are unavailable, as is normal, but this data partition can still be accessed.

How can I transfer over this data back to internal storage (the internal storage on my droid 4 is 8gb) and set the phone to use the internal storage as the default storage space?

Thank you!

Phone is rooted.

It may be partitioned for apps.

From a Sprint Moto X using AC forums app

How would that have happened and how would I change it back?

Even if I plug in the phone to the PC, I can only access the internal storage (8gb) and the SDcard (32gb) but the "data" (3gb) remains unaccessable by the pc, and can only be used by the phone.

Upon further investigation of the issue,,, I belive It does have something to do with the moving apps to SDcard (possibly)
linking /data/app folder.
Now, How could this folder be unlinked?
