Continued problems with crashed macbook

[BarneyRubles]

Hi, recently I asked a tech about my crash macbook
http://macosx.com/tech-support/laptop-macbook-crashed/344526.html
I didn't have an external hard drive, and by the time I bought one, the support chat thing had expired. But I finally have one now. Anyway, I'm trying to save my files using the external hard drive and the instructions that the tech gave me.
"Don't give up on your files, yet!
If you don't have a backup of those files, then you should attempt to get those files.
Here's what I would do:
Get an external hard drive.
Boot to your OS X installer DVD. Run Disk Utility from the Utilities menu. click on your hard drive, and click the Restore tab. drag your internal hard drive to the Source line. Drag your external hard drive to the destination line, then click the Restore button. That might back up your files all in one step. You may need to wait for several hours for that to finish."

I just tried that, and it worked fine until I tried to drag my external hard drive to the destination line. It dragged it over and then let it go on the destination line, but nothing appeared. I was wondering, why might this be?
Thank you for your time.

Your external hard drive probably should be reformatted as a Mac volume. You're in Disk Utility already, so select that external drive from the list on the left - be sure to select the line with manufacturer's info. Click the Partition tab. Click the drop-down for Volume Scheme, and click 1 Partition. Make sure that Format is Mac OS Extended (journaled). Name the Partition, if you like. Then, click Apply. Takes just a few seconds, and you should have a good Mac volume, and you should then be able to drag that volume into the Destination block.
