Hello,
I had a big problem with my PC which is now fixed many thanks to the members of this panel.
Now I want to know if there is any software that can clone my hard drive so that if there is any problem I can just use the clone hard drive since I don't have a restore disk or is there anyway I can make a restore disk .??

I use Norton Ghost works a treat. Other option is Acronis True image but I have used Ghost for ages. Both of these will create a backup to dvds/cds or a partition. I back up to partition and then store it on seperate hard drive as this is quicker. A fully loaded system backed up to dvd will take ages to back up. I would also copy my copy if you know what I mean just in case one of the dvds gets corrupted

I would add another vote for Norton Ghost. I have used it both commercially and privately and through its simplicity, it has never failed to do what I need it to do.

Here are two free and open source alternatives

Clonezilla
