I have my SSD on EXT4 and my shared data drive on NTFS. Unless anyone can think of good reason not to, I want to move the Trash folder out of the cramped SSD onto the NTFS partition.
Any horror stories or problems?
My guess is that you will run into problems, since NTFS does not support Unix permissions. Try out deleting and restoring a few files before you move your trash there for good.
That said, I found that a regular backup is a much more safe solution than Trash, and you can back up on the NTFS partition just fine.
