I'm not sure how to explain this in the subject better, so the "question" may not be right. But here goes. I have three hard drives. Drive A is a 320GB drive, Drive B is a 80 GB Drive, and Drive C is a 1TB Drive. I've copied the data from the 80 GB drive over to the 1TB drive, and am going to resize the partition (so I can copy the data from the 320 GB drive over next).
My question is this: If I boot into the operating system on the 1TB drive, can I use dd to copy the 320 GB drive over to another partition on that physical drive? I know that I shouldn't copy a live partition over (meaning I couldn't copy the data from the 320 GB drive over if I'm running that operating system).
My reasoning is this: I tried using Acronis TrueImage, Partition Manager, and Image 4 DOS/Linux (both applications), and it was going to take over a week to copy the data over. That means that for a week, I'm not able to use the computer, which isn't acceptable (unless it's my only option). I'm hoping that this works, so I can at least use the computer while I'm doing the copy.
If I have to, I can either boot to a Live CD (not really a preferred option) or use "Drive B", but I'd like to remove that drive as soon as possible.
Thanks, and have a great weekend.:)
