Honestly to make this easy, here are some steps you can follow, since I believe this to be the better of the 3 mainstream external 2.5" drives (Toshiba, Western Digital, and Seagate).

1. Why bother with the software in the first place?? just reformat the drive, or delete the software. Sure it is a bit annoying having 40 gigabytes taking up space right out the box, but is that really the only main source of concerns for this drive?

2. Now for the USB cord. out of the multitude of variations of 1tb usb 3.0 drives I have run and tested, every manufactuer has just about the same length of cord. If you want a longer cord, and or are wondering how you are going to power this drive other than with the supplied USB, then why are you buying this particular external HDD? this model is not for you if you are NOT an on the go type of person. what I mean by that is, if you do not lug your external drive around, why dont you go buy a powered 3.5" external HDD model for the same price as you would this one and have twice the space?

3. As far as the construction of the drive goes it is solid. I have tested the Toshiba 1TB 3.0 as well as the Western Digital 1TB 3.0, and my opinion is that Toshiba and Western Digital were too concerned about how slim and compact they could make the case of their external HDD, which has resulted in may more failures of those particular brands than I have seen from Seagate. Small shocks, such as light drops and accedental shock is a killer for the Western Digital as well as the Toshiba more than the Seagate models I have seen. Yes I know that there are about 3 or more warning labels stating the these drives should never be hit, moved, droped, abused, etc...

I got this with one purpose in mind - to get the MP3s off my hard drive. (Seagate apparently wants me to use it for movies - more on that below). I have so far found it to perform flawlessly, with a few caveats:


- My laptop (WinXP) treats it like another hard drive, so I can drag-and-drop stuff directly onto my player, and can extract winzip files on the drive to another directory on the drive, and move stuff around in general.
- It runs off the USB power, so no need for a power cord
- The upload transfer speed (USB2) from my internal hard drive is just over a gig a minute for MP3s - I moved 18gb of music, in files of between 2 and 5 megs each, in just over 17 minutes, and 5 gig of audiobooks, in zip files of up to 300meg, in 4.5 minutes. This may change as the disk gets more fragmented.
- This will be upwardly compatible for my next laptop, which will probably have USB3.


This isn't so much an external drive as an internal drive in a case. The "GoFlex" connector (which is not shown in the pictures) is a bus-to-USB adapter, and other adapters are available (Seagate FreeAgent GoFlex Upgrade Cable USB 3.0 - STAE104). This is great for sharing files, and perhaps for eventually putting multiple drives in a jukebox or desk brick, but it means there's a third bit of electronics between the USB cable and the drive, with all the potential for loss and breakage that implies. The connection was already a tiny bit wobbly right out of the box, though I note that the snaps are metal, not plastic, which does mitigate. (The drive says "Made in Thailand and assembled in China" Sheesh).

After only 6 weeks of use and no noteworthy physical trauma, this drive failed catastrophically, corrupting most of the data on it in the process. I wish I listened to the voice in my head saying, "Hmm, this doesn't seem very sturdy," when I took it out of the box, but I instead used it as planned for housing files I need at home and at the digital lab that I use for work. As another reviewer observed, this hard drive had an annoying spontaneous ejecting habit. My real problem was when it imploded - with a backup in progress - after less than 2 months of use. It was functioning normally one minute and then the drive's light started blinking and my computer was unable to recognize it. We tried the drive in another enclosure and hooked to a linux computer that usually will recognize even corrupted drives. Nothing. The data recovery lab I ultimately sent it to had to replace multiple "physically damaged" components to restore functionality and found more than half of the data was in fact corrupted. Mind you, this drive had never been dropped and travelled primarily in a protective camera bag. Call me crazy, but I think that a drive billed as "ultra-portable" should be able to withstand a few weeks of regular desktop use and the occasional commute. Do not recommend.

Note: I have a few older Seagate external hard drives (different models) that I've used for 1-2 years without incident. I've travelled extensively with them and had nothing but good things to say. That's why I went with Seagate on this one. I might even have been able to forgive the company its obvious construction and quality departure on this line but for the nightmarish customer service experience I had with Seagate after the drive crashed. Suffice it to say, I've sworn off Seagate products indefinitely.
