The problem is that I have only few information.

One is a broken > du utility or a broken kernel. It's not just the du utility. I have burnt the image to a CD with recent cdrecord and there were no problems. When I mount the CD under Linux (2.4.27) I see some files (exactly those needed to install the software (Maple in this case) under Linux) But when I access the same CD under Win2000 I see totally different files (excatly those one needs to install the software under Windows) So the image size is nearly the sum of the sum of filesizes seen under Linux and Windows. > Did you try isoinfo? Yes, but it didn't help me, here is the output: isoinfo -debug -d -f -J -p -R -s -l -i maple9.51_su_win_mac_linux.iso CD-ROM is in ISO 9660 format System id: LINUX Volume id: MAPLE95 Volume set id: Publisher id: Data preparer id: Application id: MKISOFS ISO 9660/HFS FILESYSTEM BUILDER & CDRECORD CD-R/DVD CREATOR (C) 1993 E.YOUNGDALE (C) 1997 J.PEARSON/J.SCHILLING Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set sequence number is: 1 Logical block size is: 2048 Volume size is: 148416 Root directory extent: 28 size: 2048 Path table size is: 92 L Path table start: 20 L Path opt table start: 0 M Path table start: 22 M Path opt table start: 0 Creation Date: 2004 08 26 07:21:24.00 Modification Date: 2004 08 26 07:21:24.00 Expiration Date: 0000 00 00 00:00:00.00 Effective Date: 2004 08 26 07:21:24.00 File structure version: 1 Joliet escape sequence 0: '%' 1: '/' 2: 'E' 3: '' Joliet escape sequence 0: '%' 1: '/' 2: 'E' 3: '' Joliet with UCS level 3 found Rock Ridge signatures version 1 found I just wonder how one can create an image (probably with a dirty trick) which looks like a correct iso image to Linux and Windows but with totally different contents. Sorry, I don't have more information.
