Hello....I just purchased an iMac and added additional RAM and am happily learning how to use it...I love it! I had been a PC user for many years, but always longed for a Mac. Finally, I was able to get one 
I have two questions and I would appreciate feedback:
1. What type of DVD media do I need to purchase for my iMac (DVD-R, DVD+R, DVD-RW)? Also the same question for the CDs. Is there any particular format the Mac requires, or can I use any format?
2. What kind of external hard drive do you recommend? I tried a Toshiba but it would not show up at all in Disk Utility or on the desktop, so I returned it. Before buying another HD I wanted to get the opinion of other Mac users who have external hard drives that work well with the Mac and I can just plug in without having to format (either Firewire or USB) and immediately use with Time Machine. I have a 500 GB hard drive so I would think 1 TB should be sufficient for an external drive.
Thanks in advance!
