I'm not sure.. The latest version of bittorrent (according to the 
homepage) , allocates space when it is needed , instead of allocating 
all the space when starting the download. This can now lead to high 
fragmentation (as any file changing size can be fragmented)...

The bad chunks are simply discarded and the download continues. These 
chunks are then downloaded from other sources and this is repeated 
untill you get the full file , with the correct checksum... It's the 
same idea behind the protocol used in xmule/amule/emule/edonkey. 
Download each part , check it and download from someone else if it is 
not valid.
