I've not read the rest of the thread but I think you need to be carefulto set the blocksize in this use case.In my notes I have:mkudffs --blocksize=2048 $LD(where LD is the loop device)Hi Tim,Thanks for the info, perhaps someday it may be useful.The use of UDF was based on assumptions that later proved to be not valid and I am now using xorriso to create the image in ISO9660 format.Bob
