I think the obvious answer here is the "New" !! drive is a USED, older (2010) than the original drive (2012), and was probably removed from a PVR due to it being faulty, sold on by someone who, like the OP, presumed because Windows recognised it and SMART said OK - that it is OK.
Too many people, unfortunately, believe that Windows is to be relied on 100% it is not. The Humax does not use NTFS or FAT32.
Fit a NEW, as in brand new, drive and all will be OK, as your laptop drive has proved. Return the faulty second hand drive for a refund!
