what kind hard drive would you recommended? if i going to buy one
You have to use a laptop HDD or SSD (2.5 inch). I used this 1TB drive but any 2.5 inch drive should work. I bought this one because it was on sale at the time. It happens to be the same brand as the stock hard drive you will be replacing but there is nothing special about it.
If you are going to go with a drive smaller than 1TB it's probably not worth the time or money to upgrade from the stock 500GB drive but you could go with a drive larger than 1TB if you want.
I'm not sure why it's doing that. It must be a feature of the new forum software. I noticed that it did that with my inFamous post in the game deals thread too. All I'm doing is posting regular Amazon links and it's changing them to those pictures. I'm not even sure how you and Zookster are posting Amazon links that still look like regular links.
There's probably a system that automatically converts Amazon links to the ad-based picture. It probably uses an ad system that the blocker removes. To get around this, write some text and highlight it and add the hyperlink to that
