Trying to download the Kanotix .iso using Knoppix.

Tried using Firefox and Konqueror, and different mirrors, but the same thing happens. After about 80Mb of download, the CD-DVD drive jumps into action and the system grinds to a halt. The first time I had to do a hard reset.

Is this something to do with disk space allocation..? This is a brand new laptop with a hard disk partitioned into four, being three ReiserFS partitions and a swap.

Help really appreciated.
