I bought an RL disk pack on Ebay, supposedly for an RL02 drive. It
is a Memorex "Mark III T"
the pack is defective (factory servo tracks are trashed)

You bought a generic 5440 style pack. I saw that listing and the
seller didn't know what he was selling.
DEC packs have custom servo tracks. If it don't say 'DEC' on it
it is highly unlikely to work in an RL0x
