Unresponsive harddrive I have a similar problem. I have a SimpleTech 320 GB external harddrive that fell when my brother was pushed into the table. It starts up (Spins), clicks, dies, starts up, clicks, dies, starts up, clicks, dies, and then there is no response.

Hard drives do not like being dropped, this is a sure way of killing your hard drive.

Inside this External HardDrive is I believe a Internal Laptop HardDrive. On You Tube there are videos of how to dismantle it, just type the name in You Tube and if you get leads you should be able to connect it inside a P.C. and retrieve yours important files.
If the connections are the same as an Internal P.C. HardDrive your in luck.

If you get no joy using the Troubleshooting Guide then try this...
You will need to check You Tube to find a Dismantle on your product and follow the step guide on here, the procedure should be similar.
Check 1st that your External HDD has an P.C. internal HDD inside, from You Tube, before dismatle of your External HDD.
Once your happy that it has continue reading and follow the step guide on the link below.

Loose connection inside the Drive case. Remove drive and check internal wiring.

If it was running at the time it fell, the heads crashed into the platters, and the buzzing you're hearing is the dents left in the platters spinning by 7200 times a second.
Not good. Likely will need a professional service to recover the data.

If you really can not get it to work anymore, you could try opening it up and connecting the hdd directly on a IDE/SATA port in your computer. This will only work if you have a desktop, for a laptop you would need all kinds of converters.

I had the same type of problem and found when I took the cover off that the harddrive worked loose from the plug. Pushed back into socket and reassembled, works great.

i am afraid that the drive has gone, but you could try to fix it using disk manager application.

It has to do with the way computers count. Computers count in binary where we count in decimal.
Hard drive makers list there drives capacities in the decimal format, where windows lists it in it's binary format.
Wikipedia has a good explanation.

Also, the drive may have some preinstalled software on it that could be taking up a bit of space (it's usually not much).

i doubt you can do anything about it. Code 10 is a hardware failure, so you will have to return it and get your warrenty.

my advice to you is open it and unplug the one touch button.
