Apple's HFS+ doesn't suffer from fragmentation in the same way that  
Microsoft's FAT32 and NTFS file systems do, and OS X takes great  
pains to keep files smaller than a fairly large size (20MB?  I don't  
remember the number precisely) contiguous on disk at all times.  Odds  
are that something else is wrong.

If it doesn't happen any other time, I'd suspect YouSendIt.  If it  
happens with other programs too, I'd recommend checking to see if  
there's a firmware upgrade for your machine, and considering an  
upgrade to 10.3 or 10.4 -- power management has improved considerably  
since 10.2.
