Using clonezilla-live-20100521-lucid.iso it goes through the same 
motions as it would with a 512 byte sector disk, duplicating the initial 
offset of 63.  I don't think there is any way for it to tell the 
difference, since the drive reports 512 byte sectors - but is slow 
unless you write 8 at once on the right boundaries.

But, something seems to be wrong with partclone's (v0.2.9) math. Right 
now it is saying:
Elapsed   03:11:52
Remaining 01:47:25
Rate      235.94 MB/min

But the progress bar says it is 6% done (which is probably about right).
