Drive makes loud clicking noise & eventually fails.
The symptom:
Drive works fine for the first few GB's, and once it gets somewhere around 50 to 300 GB, it starts making loud clicking noise. The more data added to the drive the more frequent the clicking noise become and eventually the drive fails.
Analysis:
As the first few sectors of the platter / platters, the traveling distance (from the edge of palter to the center) for the head arm is not that great. But as more data gets written to the disk, inner sectors of platters gets occupied with data. That's when the problem starts.
Without going into technical details, the issue here is not the drive. It is the PCB (Printed Circuit Board) that is installed in these external enclosures. This board regulates & provide power to the drive and in simple terms, there is not enough power for the disk to spin and for the head arm to extend far to reach inner sectors of the platter / platters .
I have tried many solutions recommended on the internet, including a youtube video posted by a person identified in this video as Bruce. None has worked. Some others suggested to change the usb cable, others suggested a firmware upgrade, some suggested to send the drive back to Seagate for replacement. Some people has done that but they got a new replacement drive that did the same clicking noise, and had to be sent back again. Do not waste your time on these suggestions, because I have tried them all before I started looking & analyzing the problem myself.
Seagate is well aware of this issue, but not only they are down playing the extent of this problem, they continue to sell these defective external boxes. In fact the first time this issue was reported on Seagate forum was 06-19-2009 06:50 AM. Up to the writing of this review, there are more than 31 pages from thousands of people reporting the issue with clicking noise & drive failure on Expansion boxes.
Solution & your options:
1 - If you just bought an Expansion, return it while you can get your money back.
2 - If it is under warranty, do not return it to Seagate. If you do, you end up with another defective drive that you have to send back again & each time cost $15.00 to $30.00 just for shipping (inside U.S.). Do one of the following:
A) Buy a new non-Seagate external enclosure (many good brand are in the market between $14.00 to $39.00). Take the drive out of Seagate Expansion enclosure and place it on the new one (this may void your warranty, but it is a permanent fix). Yes, You have break the tabs to open it. Seagate purposely made it non-serviceable.
B) If you can find a PCB that matches the Seagate Expansion box power & USB port openings, replace the PCB.
In my case, I replaced the case with a new enclosure.
C) Never buy a Seagate drive. They have been less than sincere & straight forward with their customers & continue to sell a defective product that they are well aware of it. Seagate Expansion 2.0 TB USB 2.0 Desktop External Hard Drive ST320005EXA101-RK
I can't speak to the issues that some of the other reviewers have had, but I have to say I've been very impressed by this drive. You've got to plug it in so it's not really an "on-the-go" kind of drive, but that's not what I needed. I have a couple of FreeAgent Go drives for that (and the reason I went with Seagate this time is because I've been so impressed with the other Seagates). This time, I wanted a big drive that I could use as a Time Machine backup for my MacBook Pro, and as a backup for all of the video files I've shot over the years. So far I've been very happy with this drive. One thing I noted right away is that it actually has slightly more than 1TB of space! With every other external drive I've ever used the actual amount of usable memory has been a bit less than advertised, even after I've reformatted them. With this one you get what is advertised. It's a USB 2.0 data connection, and from what I've seen manages to move files more quickly than my older Western Digital 500GB desktop firewire drive.
For comparison, I tried moving a 2.15 GB video file back and forth between my laptop's hard drive and a few of my external drives. This one was fastest at both downloads and uploads - it would download the 2.15 GB file in one minute, 17 s. as opposed to 1 min., 40 for the portable FreeAgent Go and 1 min., 37 for the Western Digital. Uploading results were similar: it would upload the same 2.15 GB video file in 1 minute, 10 s. while the other drives uploaded in about 1 minute, 20 s. So, it's pretty fast and does exactly what I need - I've got no complaints and am very happy about the price (which turns out to be almost exactly what I paid a year or so ago for my 320GB portable drive and much less than what I paid about 3 years ago for my 500 GB desktop drive). What's not to like?
One more thing, for Mac users. While this drive is set up out of the factory to plug and play on Windows it can easily be converted to a handy Mac drive. Here's how:
1. plug it in to your Mac, using the USB 2.0 cable provided with the drive
2. open up your applications folder, search for the utilities folder and then run "disk utility" (or, just search for "disk utility" in finder or spotlight and click on it).
3. you should see an icon for your "1 TB Seagate Desktop Media" drive in the left column of "disk utility" and also a drive partition (as I recall it was called "desktop" but I changed the name) underneath that.
4. click on the icon labelled "1 TB Seagate Desktop Media" and you'll see a few options in the window; click "partition"
5. after this steps will vary depending on what you want to do with this. For what I wanted, I decided to create two partitions on my hard drive. So, under "volume scheme" I selected "2 partitions" then clicked on the top one and set it to 250 GB and that left 750.10 GB on the other one. For the "format" I selected "Mac OS X Extended" but you'd want to select the journaled option if you want to use either of these drives as a "boot disk". I didn't. Then hit "apply" and it will erase everything on the disk and break it into two sections.
Now when you plug in the hard drive two icons will appear on your desktop, as if there were two separate external drives. I use the smaller one for regular backups and the larger one for storing all of my old video files. I'm sure there are lots of other ways to get an excellent value from this sleek and handy little drive. Enjoy! - Seagate 2tb - 2tb - External Hard Drive - Usb Hard Drive'
