The last time a discussion as such arose, I took some notes which I believed
I would find valuable one day. FWIW (apologies about authors not attributed

I second that, dd, man dd

boot sector: dd if=/dev/hdd0 of=bootsect.lnx size=512 count=1 (replace 
hdd0 with drive name)

Entire drive:
dd if=/dev/hdd0 of=/some-location/hdd0.img (make sure file system is NOT 
mounted, copy to a different file system!)

and theres also QTParted, you can find it on system rescue cd 



I agree, dd.  Great for linux,

dd if=/dev/hdax of=path/file.img bs=1024

How do we get the best performance over network with ethernet mtu?

you could also dd to several files such that each file will fit on CD.. or 
even Zip them before puting them on cd.

anyone know if you can send dd output to gzip on the fly and have it stop 
when the compressed image reaches 650MB or 4GB and start a new image?  You 
can obviously output a certain number of sectors with dd, but there's no way 
to know the effective compression ratio of any given set of random files...

dd just doesn't work with windows xp because of certain Security IDs written 
to the disk at the time of install which depend on hardware information. 
Ghost is able to reproduce this.

Does anyone know of another product (for windows 'ghosting') with more of a 
'free software' licensing attitude?

Older version might be a problem but:

Newer versions of Ghost will do it, as above.

Ghost for Linux:

Somewhere, just out of sight, the unicorns are gathering.


It looks like there's a version of dd called "sdd" that's supposed to be

Looks great, but I don't see any disk-to-disk option in there. Is there
