how about this one, why can't i clone the entire thing?
can i reformat my other hard drive? since they are giving me an error
sd0 doesn't exist. I believe you want a device spanning the whole disk which should be sd0c (i.e. slice 2 = overlap) instead.
A media error while reading the source disk isn't exactly a good new. Perhaps should you start to focus on some "Plan B" ...
# dd if=/dev/sd0c of=/dev/sd1c bs=256k
this would clone the whole hard drive?
sorry for being noob...and "Plan B" would mean?
Assuming the source disk is readable, that will copy all of it to the destination one.
Nothing Solaris related: plan B - Wiktionary
Do i need to do something on my target disk? I mean do i have to format it or something
hehe 
i mean do you know of any Plan B action?

Update:
I did a cloning on partition by partition, but first i formatted and partition the target hard disk to match the source hard disk.
Question do i need to mount the cloned disk when i use it eventually? Because frankly speaking i don't know where to start if i need to mount it.
