Summary: I purchased the 1.5TB version in the spring of 2009 for use with my 24" iMac 9,1. Maybe I've just been lucky but I have been using it constantly for Time Machine backups and other small storage for almost two years. It has performed flawlessly. The only 'problem' I have with it is that it tends to spin down too quickly. Many apps will enumerate drives on startup and they will 'hang' until the drive spins up. It is only three or four seconds but it is annoying.
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: Don't have much experience with this yet, just received it a couple of days ago. Plugged it in to my macbook pro running OSX 10.4.9 and it "just worked", no problems. Small, looks good, completely quiet, 5-yr warrantee. The mac reports the drive's capacity is 931.19 GB. However, I'm writing this to warn mac users about one thing: it has a bright light, which shines both through the bottom and through the little logo-thing on the upright panel, that is on whenever the...
Summary: Since my Mac Mini came with an 80GB hard drive, I was desperate for more storage. After much research, the Seagate FreeAgent 1TB external hard drive was the best solution for me. The drive is clad in brush metal and white plastic trim, which matches the color of most Mac Desktops. It transfers data pretty quickly through the Firewire.
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: My computer consultant recommended this product to safeguard my personal information in case of computer failure -- it's nice to know my new information is automatically stored on a daily basis -- if my computer crashes I have up-to-date backup. I assume it is working well -- it has not yet been tested.
