Hi. I have a Seagate ST31000333AS that was installed in a (not very good) NAS, the Iomega Home Media Network Hard Drive 1TB. After 3.5 years (more or less) of continous use (rarely it was powered off), it crashed and I wasn't able to access to data (months ago it crashed, but I could recover with ZAR the content and reuse the HDD).

It was kept some years, until I had some money to take it to any place that makes data recovery jobs. I chose the cheapest: it wasn't even a lab, but a repair center where they send HDDs to a third party (some guy, not a lab).

Before I gave it to the recovery guys, the HDD autopowered off when I connected it to MOB (yyyes, seems to be a bad thing)

They said they had to change parts in the HDD, but didn't specify what. They show me the files: all classified in folders by common types (and, of course, nothing about the not-that-common ones). They were most of them duplicated. So, that guy achieved to access data, but did a poor job recovering the files from the file system (you know, I just used ZAR and was excelent, even with some folder structures!)

Now I got some files recovered (some of them corrupt, cut, etc.), but I miss other ones. The HDD now, if I plug it to the MOB, sounds perfect, like everything's ok. But there is a problem: it reports to the MOB that its size is 0 bytes.

I've never done something about repairing HDD that goes beyond software stuff (recovering files from corrupt file systems). So, my question is: how could the size be fixed? Maybe through TTL? Would be "that" easy, or what do you believe about this case? It would be great if I could try to use ZAR by myself again now that the HDD is alive again; but with a 0 bytes size, ZAR refuse to access.

Cheers!

Reporting a size of zero is often a sign of a translator issue, which can't be fixed without equipment like a PC-3000. If you could get terminal access to the drive without a PC-3000, you might be able to issue the right commands to fix this, maybe somebody on here can give you a short howto on that.

Let me get this straight....they gave you back your recovered data on the same original drive that failed??? :shock:

That would be awesome. But if any can say, at least, about the procedure in general, just to know if it's too dangerous or complicated, would be appreciated. If so, maybe next time I have money again I'll take it to a serious lab.

No, they gave me the content in other drive. But I asked for the original one, being aware that not all my data was recovered.

So, no alternative ideas? PC-3000 only to fix the reported size issue?

So, to put this in right words.
You had a drive that was failing. You had some bad sectors problems, and recovered data with ZAR.
After that, you continued to work on HDD for some time , and heads died.
Guys changed heads and recovered what they could.

It does not mean that they did a poor job, hdd platters might be damaged. Maybe they did best job it could be done.
Someone with more experience then you can be the judge of that....

Sorry for the delay, I thought I had e-mail notifications enabled and assumed that no one answered these days.

What I said is that they did a poor job after repairing the hardware issue (with the file system). I'm mad about it because I think that they made a great hardware repairing job and didn't use ZAR (an easy program that any person with an average common computering knowledge can use, and I would be so surprised if they don't know it). I understand that they prefered to use a faster scan program that just search for common types (jpg, mp4, doc, etc.) assuming that I don't want (or I will be enough happy dismissing) to recover not-that-common file types (several music program proyects, wav files, etc., none of them recovered). I didn't expect this, so that's all because I'm mad and made that judgement. If the problem was that for any reason the data in the disc was so messed up that even ZAR can't recover as well than the other program they used, ok. It's allright for me even if it would be more complicated to scan for not-that-common file types and refused: then I made a wrong judgement and I apologize. But I wouldn't know how, ZAR makes a whole scan, it doesn't repair any TOC as far as I know and when I used it recovered, if not everything, almost (with no file corruptions, by the way).

And they returned me back the HDD (with resistance) reporting a size of 0 bytes, so I can't try ZAR (or any other program, I guess) by myself. I just wanted the hardware reparation (not the flie recovering), but I understand that they only offer a complete job.
