The first thing you've got to do it find out what about the files is different. Go here http://www.picturel.com/utils.html, get TiffLoad.exe and run it on 1 HP image and 1 Microtek image, by going out to the Command Prompt, type Tiffload FILENAME. For now, put the *.exe in you test directory.Onscreen will display more info in the TIFF header. Look at the 2 files and compare. Maybe your one is not an LZW.
Also, the files that won't open in PhotoShop, convert from TIF to TIF using another program. Saving the file again will rewrite the TIFF header and may help.
