I have a share called Media that has an Allocation Method of "Most-Free" and Split Level of the first 2 folders with all disks included.  This has been working great until I added a new disk yesterday.  I added the disk and formatted it, after preclearing.  Last night I copied over about 1 TB of movies from my other NAS (exactly what I have been doing previously and has been working) and all 300 movies copied to the new disk only.  Using the Most-Free Allocation Method it should make that assessment for each file copied, but they all went to the new disk.  Any thoughts?

 

The Split Level is correct and has been working great before the new disk.  This is my structure:

 

Media --> Movie Folder --> Movie Files

What is the sizes and free spaces of the other disks that means the newest one does not have the most free space?  Perhaps a screen shot of the Main tab might show why you do not think that all the new material should not be going to the new disk.

The other disks were at 400 GB, but I would expect once the new disk grew larger than the others it would pick another disk (which I have seen previously).  The new disk is now 1.36 TB because it kept copying the files to the new disk and none of the other ones.

 

Picture attached.

If you look at your free space, your new disk (disk5) still has the most free space of 1.64TB while the other disks have about 1.59TB free.

so until disk5 has less than 1.59TB free, new data will be copied to disk5

OMG I'm an idiot! lol  Didn't even think about it being a 3TB drive. lol Sorry and thanks!
