The past few days, I've been fighting to get udpcast to send an uncorrupted disk image to my lab computers. The hard disks are 160GB (160000000000) with six partitions (a mix of ntfs and ext2/3/swap). During the multicast, the sender reports some time outs. After a few hours and 160GB later, the progress indicator says it has run out of disk space on the receivers. Not all of the partitions exist on the cloned disks with a lot of free disk space either labelled empty or as an unknown partition.
I'm using the prebuilt pxe linux kernel (2.6.27.6) with a cast-o-matic initrd file.
Are the casting time outs related to the data corruption? And if the disks are identical how can I be running out of space? What can I do to get a clean copy of my disk across. I've been staying up way too long trying to figure this out. Any help is greatly appreciated.

You're probably running into the seek bug present in some Linux kernels. The problem is being fixed (Linux patches take a really long time to get through the chain into a released kernel...), so in the meantime I added a workaround for it to udpcast.
You can download this version from the udpcast site as usual.
