Help on replacing notebook hard drive

Can someone tell me if I can replace my existing drive on my Toshiba Satellite A30-514 laptop with a Travelstar E7K60 hard disk?

Here are the specs of the Toshiba:

And here are the specs of the Travelstar:

I just don't want to buy something and then find out that it doesn't work.
Also if you have any other reccommendations for hard drive, I would really appreciate it.
I am gonna search for alternatives myself as well. Anything I should look for to make sure it's compatible? For example I saw the toshiba one is ATA-5 and the travelstar one is ATA-6. Will my computer support ATA-6?

Thanks

Standard name is somewhat confusing recently. Each organization gives different appelations to the same thing. Now it seems that ATA-5 is the appelation given to ATA-66 and ATA-6 is nothing but ATA-100 by ANSI standard. If so, even if the laptop doesn't support ATA-6, it should work as ATA-5.
