I'll tell you what's most likely wrong - you're storing your extracted ISO images on a FAT32 filesystem which doesn't support file sizes larger than 4GiB. That's why DVD #1 works, it's explicitly reduced in size to fit on a 4GB USB stick too. -- Steve McIntyre, Cambridge, UK. st...@einval.com "Further comment on how I feel about IBM will appear once I've worked out whether they're being malicious or incompetent.
