Hi there!
Today my external usb hd stop working.
It seems to be a physical problem because it does a weird noise and nothing appears in dmesg.

Ps.:The driver is not stucked the plates runs, the needle moves e the led keeps on, but no blinks.I have already opened it but no success.

This was the last "talk" between my system and the HD:

Is it one that uses a SATA to USB adapter bridge board, or is the USB board build right onto the actual hard drive?

Hi,
Yes it is USB board build, no adapter.it does a repetitive sound.
The HD dont suffer any impact or damage, i dont have a clue about it.

I just put a video on Youtube, maybe it can help:

Yet another opened drive!

I read that people used to spank/smash it to bring back to life
Open it was the only move left for me...

nothing like a good joke

Well this HD was a totally different experience to me, i had a similar problem with a WD external drive months ago but it occurs after an impact.
This one was working fine until that I/O error, then zero communication with PCs, Notebooks, Mac, tried with other cable and etc...
Thanks God I did backup of major things and loose nothing really important, but its annoyng because this drive is about a year life.
I am really thinking adopting SSD or a bunch of bigsize pendrives to carry on with me instead of an external HDD with mech parts.

Regards,
Bruno.
