I was attempting to copy between two USB hard disks (dd if=/dev/sda1 of=/mnt/sdb1/ntfs bs=1k), when I got an error saying the maximum filesize has been exceeded at 2GB.

Has anybody had this experience? sda1 was ntfs, sdb1 was ext2.

This exact same command worked fine for me in Knoppix 4.

i can't quite remember, but i think there's a limit in the default busybox dd. try installing gnu-utils in the repository (system or testing) which has a different dd.

(also try searching these forums).

for others with this prob: goto apps->Tools->Upgrade to gnu-utils

I will try that out. Thanks!

Old thread, only saw it now.

It sounds like you're trying to copy to a fat32/vfat filesystem on your usb drive. These filesystems have an effective filesize limit of 2GB.
