More on this. I did once in the past by replacing the board from an identical HDD that was mechanically broke down HDD, and yes, it worked perfectly. But before running this procedure there is one way to check whether the drive head is still in good work. Try to connect it to HDD power line, then listen closely to HDD (luckily I have stethoscope at home ) if it only wheezing smoothly then it probably good to go. But, if you hear a continuous ticking sound (like a clock sound), then it most likely already had a serious mechanical damage.

But hoping it only as what have been said above. (linux or Mac formated )

Kevin, now you worry me. I have this Maxtor external 640GB HDD. It is clicking since day one - and that since 5 years. Works perfectly though. Should I give it a closer inspection?

On the other hand my Seagate external just gave up. It never clicked. Fortunately I had just transferred the data to the clicking Maxtor. So there is no data loss.

I wanted to take it out of the enclosure it came in to see whether it is the disk or the electronics. But there is not a single srew to open that bugger. Hate to take the hammer - LOL.

Wolfgang, I didn't mean to. I mean ticking in regular pace like a clock sound. One clicking sound or two is normal as the head is activated to start reading or writing, especially after being idle for some time.
If that regular ticking happens to internal HDD, it can be caused by two things.
First, insufficient HDD power line, but went it comes from the PSU then it always accompanied by other system problem such as total freezing or restarting.
Second, the HDD itself, but it's follows but intense HDD working LED indicator that indicate the reading or writing time out has gone unacceptable.

I have my transcend and seagate external HDD ticking if I connect them to poor powered USB panel. That is why I never use front panel USB for my external HDD storage and feel better by using Y cable. (Toshiba ext HDD have better way in telling about the low voltage supply by making long beep sound, I like it).
The mechanical defect, and surface defect, will give us regular ticking sound though we connect it to proper power line, and hard reading or even no reading at all.

Yes, you can do some research by opening the enclosure. Just need a set of mini screwdriver, but for the HDD you need 10 bucks special screwdriver. See the hammer as the last last option, and I love to see you do it .
If you manage to disassemble the enclosure then you have your way testing it.

Btw. I still need one board of WDC blue 2.5". I got one died just after my son was experimenting with it, instead of connecting to 5 volts source, he took 12volts cable, then the board get smoke instantly.

Lastly, this all just my experience. I can be wrong I guess.

Thanks Kevin for the explanations. But that Seagate Free Agent resists all attempts to open it. There is not a single screw. They must have pressed that enclosure together. But everything is so tight that you cannot get into it. It was a nice 3.5" disk, but after 5 years it gave up.

Most secure enclosure don't really have screw, instead they have it with an interlocking cover that can be forced to open by using a (-) screw driver to slightly disengage it, and slide any soft and flat material with firm and gentle move. Little cracking is expected, but it worth than just throw it away to trash can.

Just do it while in the right mood. Or, it will end up smashed.

Yeah, that's what it looks like. But they sure made it very tight. I will ask a friend who is a mechanic to play with it. Can't lose a lot anyhow.
