Ok, so I read this review of the mini: http://www.macintouch.com/macmini/review.html#access

Notice this part:

Quote:
Miraculously surviving the challenge of swapping internal hard drives, we formatted the fast drive and cloned the contents of the original Apple drive, newly housed in a FireWire enclosure. (The Mini didn't provide enough bus power over FireWire for the external drive, so we had to use an external power supply with it.)


So, this lead me to look around on the internet to find out more information on bus powering via firewire. My old Powerbook G4 1.5 supposedly had 7 watts on the firewire bus (http://www.macfixit.com/article.php?story=20041221081432908), and from the Mini spec's page the mini has 8 watts, so I'm thinking everything will be fine.

I'm just wondering who has tried to use bus-powered devices (2.5" drives, iSight, etc) on the Mini's firewire port and how many items were you able to successfully use. I'm also wondering why macintouch didn't elaborate any as to why they had an issue powering the stock drive in an external enclsoure.

Your guess is as good as mine!


iSight, iPod and Sony Digital 8 Camera all hooked up to mini and working fine. How many things do you want to hook up other than an external drive?

Well, I have a 3.5" firewire drive (externally powered of course), and I have 3 2.5" drives that'll be powered at various times for different OS's, backup OS, etc (not powered all the time), and an iSight. I guess my only concern is that it sounded like they were only hooking up a single 2.5", bus powered drive and that it would not work - which concerns me, as this worked fine on my 40GB 5400rpm 2.5" and 20GB 4200rpm 2.5" in external enclosures on my PB 1.5Ghz.

Thanks for your input though!

BTW, I emailed macintouch and here is their response:

I don't know *why* it didn't work; simply that it didn't, although it
seemed to be working at first. It was a Mercury On-The-Go enclosure
from macsales.com - the small plastic one for notebook drives.

Well you will love it when it comes. It was a good thing I ordered mine on the day Jobs announced it. Two weeks in and no regrets! If you have any questions about it let me know.

Good hub for Firewire and USB. I bet you'll be fine with what you want to hook up and have no problems.

I had to sell my powerbook first before I could buy it. Since it sat on the desk hooked to an external monitor, it wasn't being used as a laptop. Glad I got it out the door before the updates this week. So just a few more weeks mac-less... only been a few days and I'm pulling my hair out.
