@chriswally -Unstoppable Copier- copying large files with deep paths can cause issues (exceeding 256 chr$), along with corrupt artwork. I use Teracopy and saw similar issues, switched to system copy, slow but sure, first pass turned up a corrupt file and the copy died. Deletion of the corrupt thumbnail file became my success (might want to look through the thumbnail folders looking for half green or grey images and delete). Solution #1 is going to work, copying the userdata sans thumbnail folders should get the job done, then copy each thumbnail folder one at a time and place in the correct postition until you hit the problem child. Never look back.
