You're correct, I've found the old bootstrap.dat but I also found hidden .fuse_hidden files 
one of which was 28GB.
I'll reformat the disk to ext4, I believe the fuse NTFS is causing other problems as well which I had prior to this which I have no explanation for, such as not properly syncing and also getting stuck on the initialization and also stuck building the database...
