Summary: Once you get it working, FGS, don't touch it! The connections are so wobbly that you never know if you're going to get a power light or a message to re-format the drive, or just a low hum. Seagate is no help and the USB cable is non-standard. If you're stuck with one (like I am) just don't use it for anything you can't afford to do without. Junk. UPDATE: 2014-04-02 (not an April fools joke) Seagate extended the warranty and is shipping a new drive. Thanks Seagate.
Summary: I can't say that I haven't used the drive since it is over 2 years since purchase, but I expected a better product and it ultimately failed. I got a cyclic redundancy check error and now I'm trying chkdsk to recover data. Also, it never kept the network sharing properties I applied so I had to reset them after every system restart. Only used about 500GB of the 3TB. Might try another Seagate drive sometime but will pay more attention to the reviews.
Summary: I used this drive for about 13 months with my iMAC 27" for time machine purpose. It has suddenly died, along with all my data. I ear a rithmic tick and click when the disk is connected; Snow Leopard recognize it but is unable to read and to formet the drivesays me the the drThis was my first (and probably) last experience with the Seagate brand. Immediately i buy 2 Western Digital external hard drives and both run very fine.
Summary: I had a ton of movies, and music saved on this thing, and in 1 year it craped out on me, I lost it all, now I have to re rip all my stuff. Luckily I still have the discs, but if I didn't I would have lost it all. So all in all this is a huge waste of money.
