I struggled to find a way to convert a bunch of Plextor PXI image files to a standard ISO format. When my PC was upgraded to XP Plextor tools stopped working and there is no upgrade path. I tried ISObuster version 1.6 and it did not work, not sure why. It told me the file was blank, and I knew it wasn’t.
The answer is to download a trial version of UltraISO. www.ezbsystems.com Conversion was SIMPLE ! What a fantastic tool !
Install the program as “trial”, run the program to Tools, Convert, select the PXI file and the format you want to output, eg ISO, etc. Worked perfectly
Hope this saves some other people grief.
