fzabkar, you my friend are a genius!!!
My PCB looked a little like the photos, although nowhere near as burnt, just some discoloration on the diode.
The heat was definitely generated in that area when plugged in.
I snipped out the diode (could not desolder, my iron was not hot enough) and hey presto, it worked!!!
I cannot thank you enough I was having a nightmare trying to find the same disk with firmware match.
If you have a favorite charity please let me know and I will be sure to make a donation.

Thanks in advance from me too.
I had a Maxtor Basics USB external case, that got "fried" some days ago.
Since I cared about the data more than about the warranty, I extracted the SATA drive inside and found it to be a Barracuda 7200.11 640Gb.
(Not so) surprisingly, the drive DID work if put in a desktop PC.
I then bought a SATA-USB adapter from eBay that fried one TVS (whose name I discovered thanks to this forum), the drive board is almost identical to this one:
and the chip burnt is the smallest one on the left.
I noticed that these **bleep**ty adapters do not have any +5V GND line... I tried another disk (WD) and it didn't start (I removed it quickly before it burnt ), while after joining the two GND lines on the power adapter cable (molex -> SATA power), it worked.
Apart from blaming who sells these crud adapters without any warning, I was wondering how to substitute the diode, even if burnt, I can read on it:
ST e3 VU
AE (or AC theres' a crack right in the middle)
Is there any way to reliably replace it?

Please help me, If you see my pictures, two diodes are burnt, and if you lift them from one side, they are unwelded. http://goo.gl/photos/7HAP
Do you think the two big diodes near the burnt ones could be damaged? Wich ones do I have to cut?

Ok, i was building a system with some spare parts i had. The PSU had just 1 SATA power connector so i used one of those Molex to SATA converter, connected everything and powered on the PC and 1 second after i saw a small smoke cloud coming from the HD, unscrewed the thing and there it was, a big burn stain right below the SATA connector on the PCB, the HD was working fine as i was using it just for backups, it's a little hard to see in thee pictures but one of the small transistor, resistance ? is fried.
Is there anything i can do to make it work again? at least until i find a new PCB it's a Barracuda 7200.12

Help me I am desperate and sad, very sad
Today I broke a Lacie external HD.
The breakage has been generated by the burning of the safety diode safety of PCB for connection with power supply from 19V to 12V instead of the endowment. I enclose photos
I felt the classic smell of burning from the circuit board PCB. No sign of life of the disc.
The hard disk inside the Lacie casing is a Seagate 7200.12 1TB (http://hddscan.com/doc/HDD_from_inside.html) with the following characteristics
Seagate Barracuda 7200.12 1TB
Date Code: 10201 Site Code:TK
PCB 100535537 REV A
Please help me and tell me exactly what I can do. to recover data. Otherwise I have to spent around 1000€ to recover data.
I read to extract the diode but I cant understand what did you mea.
