Summary: Simple plug and play setup, fast and quiet. I transferred 40 gigs of info from my old drive in probably twenty minutes with the Seagate plugged into the Firewire port and the old drive in USB. The manual is breathtaking in its brevity, so you have to search the Seagate site for more info. Only a couple of caveats. I bought this drive because I was having mounting/unmounting problems with my old external drive.
Summary: I bought the 1TB FreeAgent for Mac about a month ago. I don't think I've had it long enough to rate the reliability, but installation was a piece of cake. I think it took longer to decide which of the three included cables to use, than to actually plug it in and wait for my Mac to recognize it. I think the way it lights up when active is cool. The transfer speed is seamless - I'm using the included Firewire cable and it is connected to my Mini Mac.
Summary: I purchased this product after extensive research and after my former external hard drive died. It could not be easier to set up/ install. Mac users -- be sure to look for/ purchase the MAC version of the product -- using it with Time Machine is effortless. I am very happy with the product.
Summary: I am very happy with the FreeAgent for Mac. It's quiet and has worked very nicely since I purchased it (1 month). The white light is quite bright which could be annoying depending on where you're using it. I'm using mine in a home office so it's not a problem. My only complaint is I wish it had an on/off switch so I could turn it off when I disconnect my Macbook Pro. I'm not comfortable unplugging it all the time (plus it's a pain).
Summary: Seagate ST305005FJA105-RK FreeAgent Desk for Mac 500 GB USB 2.0/FW800 External Hard Drive (Silver) Installation was easy as pie with Firewire. Took about 4 hours for 150MB backup on an iMac. I didn't bother trying to use the software but got Super Duper.
