I short-circuited the PCBs, helping a "friend".
Now, there are there, on only 2 hard drives, just 40 Gb (=work for over 2 months, daily, even sundays, for 4-8 hours/day, with the sun burning my eyes, on a CRT monitor that works on a P III with 256 RDRAM, without wearing my 4+ glasses) and, as any user, I would very much like to recover what I have there (valuable projects, not porn).
Now, being romanian, and a poor one, I have no money to send them to a data recovery (also I feel like I'm expose naked when some1 is watching in my stuff) office and I'm trying to repair them myself. Doing so, I've discovered http://damon4.com/Default.aspx?blogentryid=112. Problem is I don't get exactly how to build that device and the pieces I need.
So, as I help many http://answers.yahoo.com/my-activity (if you'll look closer you'd see that I'm not there to chat), I'm askin an expert :
- will this solution's solve my situation and, if so, could you make it intelligible to me ?
- if I mist the bathroom and switch the (spinning) discs from my hard drives into similar models is this going to help me ?
- another sites like this one http://hddpcbshop.com/ can you tell me ?
- what other option do I have left ?

Search for tvs on this forum as keyword. How did it happen though?

@OutStanding:
Due to the communication problems that I see here, I am not promising that I will give further replies, but I'll try to explain where you need to give more info:

As labtech said, more info needed:

* What happened exactly?
* Exactly why were you doing anything with these disks at all?
* How exactly do you know that the PCBs are "short-circuited"?
* What is the exact behaviour of each of the 2 disks now?

IMHO that approach is not appropriate, outside of a few limited situations similar to those described in that article.

We can't see your activity, as we are not logged-in as you! What is your point about Yahoo Answers and how is it relevant here?

I'm no expert, but see http://www.users.on.net/~fzabkar/HDD/TVS_diode_FAQ.html

As for the Damons Laboratory link, you don't usually need such an elaborate method to locate a dead short.

My pc was open cause I was trying to switch those hard drives, due to my lack of drive slots, for about 10 minutes. Of course it was power off. After I start it, well.... it happened. Shutdown, remove it, looked at it, then I connected the other one. What do you know ? I am very lucky. Literally I saw smoke coming up from hard drives. Twice. :) I'm not sure that the 80 Gb drive has the PCB in short or it's the engine, I just assumed cause, when it happened, was in similar position -stable but slightly unbalanced- as te 40 Gb one was, but on this one there are visible 2 shorts on PCB. I'm interested to find out other shorts, if there are any, with that device or.... a method to retrieve my 40 Gb.
Now, the hard drives ar dead and mute.
@Vulcan....., I'm sure that in your wisdom you could find the grace to forgive me, but.... it was really necessarily to show how stupid I am asking the relevance of that yahoo link ? I guess that it's easier to state that there are language differences and we could not understand, -not even try to-, with.... some1 like me, huh ? "It's affecting you cause you let that happening". Please assure that your (friends's) kids understand that, so I don't have to conciliate each one of them.

I was asking because I did not understand - that is all. You can (I guess?) see something at that Yahoo link, when you are logged-in, but we don't know what it says, so we don't know the relevance of whatever you can see, to your questions about the disk drives.

My previous "smilie" was intended just to show a situation which we all recognise - in the past I have also sent links to people, which are only useful when I am logged-in to a system! It was not intended to make you look stupid. But the question is still unanswered - what was shown at that link, which is helpful to understanding your problem with these disk drives? You still didn't tell us - or perhaps you did tell us, and I still did not understand. :(

You know nothing about what I did. Of course I tried to understand - I don't like to waste my time writing extra questions, but I simply could not understand you properly. Do you really want wrong answers and suggestions, because of incomplete understanding of what you wrote? I don't think you want that :-) That is why I asked questions, as clearly as I could.

However I could already see some warning signs in your original posting, about the situation which could develop. And unfortunately, exactly as I feared, your reaction shows that the communication problems here are too big, and you complained about my reply. :-( So I will stop here and let other people answer your questions (if they want to), as life is too short to waste it. Good luck!
