Hey guys,

i have a little problem with my portable Samsung G2. The hard drive is not spinning up. LED is constantly shining, but not flashing at all. I've already checked the usb jack, and works correctly. What else can i check? Thanks for any advices!

Often problem with this model is internal, with the drive's mechanics. Use the search function in the forum (even google) for your model and lots of info will come up.

I've been searching a lot, but didn't found anything that works on my model. For example TVS diode, broken usb jack... I cant even find any TVS diode on this PCB.

So if you have any advices, what and how can i check, i would be very grateful.

It is more than likely not electronics related. It is an internal mechanical failure.

Be very careful what u do if your data is important as many people do crazy things and lose data.
