When you bake and display a 32bit .tif file inside of Maya, you may obtain an error indicating that the IFF conversion failed. This occurs because Maya tries to convert the file to IFF for previewing and fails.
Workaround: Select Keep Original Shading Network under the Settings section in the Lighting/shading > Batch Bake (mental ray) > option window.
