    Dead, there are micro particles of dust in the air. There needs to be absolutely nothing between the read/write head and the platter. Since the platter is magnetic it attracts dust the moment you open it. That is why clean rooms exist, it is a room that has none or very few of those micro particles, making drive recovery and repair possible.

    Thanks. I will burn the drive later when I have time.

    I'm not trying to say that you won't ever be able to get your data back. I'm simply saying that mechanical hard drives are designed to be sealed, and by opening it you reduce your chances of recovering data. Also, a hospital room wouldn't be the place to go. If you don't know much about HDDs and data recovery from them, I'd send it to a professional company. 

    But is my hard drive dead or no? This is the question.

    I'd recommend reading something like the article I've linked below. You seem to be an expert on HDD recovery, so you should be good to go and perform your data recovery.

    I am not an expert on HDD or Data Recovery. I take the blog you posted as a grain of salt. I just want to know is it possible to revive my portable HDD? Geez. You are making this sounds like I need to go to a hospital room to open up my drive.

    @Speed Weed Even if your room is clean, there is dust. That's why hard drive repair isn't done in a clean office, it's done in complex rooms designed to filter out particles you can't see. That's also the reason that the label on the drive should specifically say not to open it. Unless you have important documents on it, I wouldn't pay to have the data recovered.

    That's not true. There are tons of videos on Youtube show people repair hard drive in their office room which is not 100% dust free.

    Yes it seems dead.

    Esp since you opened it, I'm assuming you aren't in a clean room.

    You aren't supposed to let ANY dust in there eh.

     

    There is no dust

    You probably would have had a better chance of data recovery if you didn't open it. They're sealed for a reason. Mechanical drives shouldn't be opened unless in a clean room.

    My room is clean, and there is no dust. 

     

     

    So my drive is good to put it in the grave? It contains my disk backup and some of my text documents which already got backup onto secondary drive. I just want to know if I can revive this drive to reuse it again.

    One of the biggest security stories of 2018 has been the discovery of the Meltdown and Spectre chip flaws. Known as speculative execution exploits, the flaws make it possible to steal potentially sensitive information and there has been an on-going battle to issue patches wherever possible.

    Just as things were starting to die down a little, security researchers have revealed details of no fewer than seven more speculative execution attacks. While some of these attack vectors have already been mitigated against, this is not the case for all of them.
    As detailed by Ars Technica, researchers have undertaken a systematic analysis of the techniques involved in the Spectre and Meltdown exploits, and this is how the new variants have been discovered.
    One of the newly-discovered exploits uses Intel's Protection Keys for Userspace (PKU), and Peter Bright explains:

    Protection keys introduced with Skylake allow an application to mark pieces of memory with a four-bit key. Applications set the processor to use a particular protection key, and, during that time, attempts to access memory that is labeled with a different key will generate an error. Yet again, a few nanoseconds of speculation can occur between making an invalid access (accessing memory with a mismatched protection key) and the processor reporting the error, enabling information that should be protected to leak.

    Intel, it seems, is not concerned, issuing a statement saying:

    The vulnerabilities documented in this paper can be fully addressed by applying existing mitigation techniques for Spectre and Meltdown, including those previously documented here, and elsewhere by other chipmakers. Protecting customers continues to be a critical priority for us and we are thankful to the teams at Graz University of Technology, imec-DistriNet, KU Leuven, & the College of William and Mary for their ongoing research.

    Oh man, when is this Spectre and Meltdown exploits are going to get fix permanently?! I mean for real though, the more Spectre and Meltdown exploits and patches, the more performance is going to get impact because some users have to disable Meltdown patch in order tor restore original performance. Right now, there is no known malicious application that can exploit Spectre and Meltdown, but in the future it will do if chip manufacturers don't seal the hole completely.
