Really not sure what you are saying to me here - all I know is that nothing except PS could read the file that PS wrote (including GIMP, IrfanView etc..).
To me that says the file is broken.
Most TIFF files are written such that pixel data is based on unsigned (i.e. always positive and full range) integers of various sizes. Some files are based on floating point data, which was traditionally 32 or 64 bits because that is what the CPU hardware supports and it is defined by a IEEE specification. New 16-bit floating point formats were introduced some years ago (e.g. often called 'Half').
An Adobe employee distributed a draft specification for floating point data in TIFF (as supported by Photoshop) and libtiff implemented the 'predictor' support and other key features from this specification.
Few programs know how to deal with 16-bit float data. It is usually used in High Dynamic Range (HDR) applications where file size is still an issue and high precision is not needed. There is now an IEEE floating point specification for 16-bit floats and there is some hardware support for them.
Due to the volunteer efforts of Richard Nolde (who is on this list), GraphicsMagick is one of the programs which reads such files. Since it is free, you could try it and see if it can read your file.
