How do I save a disk image of my laptop hard drive?

[Mark Phillips]

Could someone help me verify that the entire hard drive was copied?

This is the message at the end of the copying:

29302560+0 records in
29302560+0 records out
30005821440 bytes (30 GB) copied, 6036.72 seconds, 5.0 MB/s
16656403+379 records in
16656403+379 records out
17056356977 bytes (17 GB) copied, 6036.63 seconds, 2.8 MB/s

The resulting image is only 16GB for a 30 GB drive. I know I used compression, 
but I just want to make sure it worked. It does say 30Gb copied. 

Just looking for some comfort before I wipe out this drive!

Thanks!

Mark

P.S. No warrenty expected, just a "feel good" comment!
