A quite interesting discussion. Something must get logged at some point:
$ ll /var/log/lastlog
-r-------- 1 root root 1254130450140 Mar 1 20:01 /var/log/lastlog
$ ll -h /var/log/lastlog
-r-------- 1 root root 1.2T Mar 1 20:01 /var/log/lastlog
Now I wish I had a 1.2 Terabyte disk in my laptop ;). Using "ls -hs"
shows the actual size to be 52 kB.
Actually this is very close to the value reported by the OP, so
perhaps he also has a 64-bit machine. It has sort of been suggested,
but for the OP, the "du" program is very useful for telling you how
much space things take up. I especially like "du -hs *" which tells
you the size of each of the directories in the current directory.
Also, check out "df" and "df -h" Note that all of these should be run
in a terminal.
Lastly, if you are trying to use Ghost, then you actually may not be
able to go from a 160 GB disk to a 36 GB disk. Ghost, as far as I
know, creates an image of the disk, which is a direct binary copy.
You should be able to do this on a partition-by-partition basis if the
partitions are the same size, but I would still be careful. Perhaps a
better choice would be to boot to the rescue CD and simply mount the
partition to copy from and to copy to and just copy the files with "cp
-a".
