I have a KNOPPIX CD and want to make an ISO image file in order to make copies. Of the machines available to me, two are partitioned with the NTFS and one has two partitions (vfat and ext2) with one of these partitions containing at least 850 meg free space.

So, I planned to use the tohd command to generate a CD image on the hard drive and then use the CD image (=iso file) to make bootable CDs. However, on that computer I haven't been successful in running the live CD (lots of Cloop errors).

I tried to download an isofile from various mirror sites but the rate is always very slow (5 - 12 KB/sec) and generally stops after 20-40 meg are downloaded. Tried bittorrent but the program never launches.

While I see captive NTFS on the KNOPPIX system after it launches (3.4 version that was included with KNOPPIX Hacking book), I have read that it is not a good idea to enable writing to NTFS.

I would appreciate a clarification about why it is OK to download an ISO image to an NTFS partition, but not OK to copy the same ISO file to an NTFS partition.

More importantly, I would appreciate advice from others about how I might best obtain an iso image. If I launch linux on my old laptop with 850 megs of free space, is there a simple way I can copy an iso image to it without using the knoppix to hd command?

Thanks
