110 Portable Plus software, Teledisk

I think I've finally figured out why this is an issue. The HP150 originally ran DOS 2.11 and had 270K, single-sided, floppy drives. This is the format of the TD0 image on the Computer Museum's site. Later 150's ran DOS 3.2 and had standard 720K, IBM PC drives. This would explain why the 270K images can't be read and why the zipped files can easily be transferred to the HP150.
