Have you done some basics, such as double checking the cable and switching it out to test the connection?Have you restarted the computer, have you looked for the EHD in Finder under Devices? Please let us know what troubleshooting you have attempted so far so we have a good starting point.

Sorry - should have mentioned this earlier.
Yes, I have done all of this. Restarting Mac, changing wires, trying several USB ports and it also does not show up in the finder under devices, neither does it on the desktop.

Connect it to another computer to see if it shows up, I'm guessing this isn't a USB powered HD. It should have it's own power supply or at the very least be plugged into a powered USB hub.If it doesn't show up then it may have failed.

I tried to connect it to my ancient Dell-Laptop. It recognized that "something" was connected - but it showed up as an unknown device. I assume this might be, because I used this drive as my time-mashine and Win won't recognize the file system ?

OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
- Shut down the computer.
- Unplug the computer's power cord and ALL peripherals.
- Wait 15 seconds.
- Attach the computers power cable.
- Wait another 5 seconds and press the power button to turn on the computer.
- Shut down the computer.
- Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys.

You are really trying hard to help. Thanks a lot - much appreciated.
However, neither Safe-Mode, nor SMC Reset, nor PRAM Reset really helped.
I actually would throw away this HDD ... but it is not even 2 years of age and holds some of the data I don't want to lose.

Try redoing the SMC reset, make sure NO peripherals are connected. Do the reset 2x to be sure.

Tried that as well. Still no success :-(
