Hello all, I just ordered an AO532h with 250GB and want to up grade HD to 500GB or 750GB. I can't find the specs or details on the sizes of hard drives. Can anyone tell me if it takes 2.5" or 3.5"? I have read confusing posts on this. Can anyone make some suggestions on either hardware of software? What app are you using to make a disk image? I found this on the Amazon site: "Amazonian says: I upgraded to a Hitachi HDD 7K500-500 no problems of any sort. You can try [url="http://www.paragon-software.com/home/pm-express/download.html"]http://www.paragon-software.com/home/pm ... nload.html[/url] and [URL]http://www.paragon-software.com/home/db-express/[/URL]" Any comments? Thank you. Zena
