How to create copy of DVD, which ISO image size is larger than maximum size of file on filesystem? There is only one DVD drive.

What UNIX/Linux filesystem are you using that has such a small maximum file size? – pdo Feb 16 '11 at 19:14
VFAT (FAT32) in quite old kernel has limit of 4GB file size. – Jakub Narębski Feb 16 '11 at 20:51

As long as you don't mind that the intermediate storage won't be usable as such:

split -b 1024m /dev/dvd iso-pieces.
# Pop out original, pop in blank
cat iso-pieces.* | growisofs -Z /dev/dvd=/dev/stdin

Thanks. I will probably use dd or cdread instead of split-ting on device, though. – Jakub Narębski Feb 18 '11 at 12:26
@Jakub: dd is useless here, it won't do anything for you that cat wouldn't do. But see Calculate md5sum of a CD/DVD about reading a CD's filesystem image exactly. – Gilles Feb 18 '11 at 18:22
I meant using e.g. dd if=/dev/dvd of=iso-piece.2 bs=1024m count=1 skip=1024m etc. instead of split. – Jakub Narębski Feb 22 '11 at 11:08
