RAID Data Recovery – How It Works

May 11, 2018


RAID data recovery is probably one of the most complex processes any data recovery firm can perform. More often than not, the problems are compounded by the actions of the client prior to sending the drives in for recovery. Many users feel that it is important to try and recover the data themselves or repair the array through various system utilities, and this may be fine if the data is not critical. However, it has been our experience that when you have a RAID failure that has resolved in substantial data loss, more often than not, somebody's job is on the line if that data is not recovered. The largest piece of advise this article can provide in the event of a RAID failure: LEAVE IT ALONE.

IT professionals have a lot of pressure placed on them when a catastrophic system failure occurs. It is their job to make sure that all systems are up and running. Many times, out of panic, troubleshooting processes are initiated in order to correct the problem. Often times these processes only make a bad situation even worse, and in many instances they can render the data unrecoverable. Let's keep in mind what this data can consist of in an average corporate environment. You are probably dealing with information that cost many hundreds of thousands of dollars in labor and resources to create. Much of the data probably can not be duplicated. The intellectual value alone could have been in the many millions of dollars. Corporate executives really do not care to hear about how the failure occurred, or what unbelievable string of events led up to the server crashing. They do not care to hear the technical jargon as you try to explain to them what happened, and hope they understand that it was not your fault. They only want to know one thing … "Why was this data not backed up, and how can we get it back?"

Instead of taking chances on your own, call a data recovery professional. RAID data recovery can be expensive, but in most cases it is much less costly than trying to recreate the data that has been lost. There is a set procedure that most data recovery professionals follow when it comes to performing any recovery work. These procedures are followed and expanded upon when dealing with a RAID recovery. The first step of any RAID recovery is to make sure all of the drives are functional. In order to properly complete the recovery it is essential that all drives are fully functional (this is especially true with a RAID 0). This may involve taking any physically damaged drives into the clean room, in order to make the necessary repairs so that they function normally again. Once that is completed the next step is to make complete, sector-by-sector clones of every drive. This is not "Ghosting", but a very low-level process that allows the recovery technician to work around bad sectors, and have complete control over how the drive functions. During the cloning process, the original source drive that you sent in, is generally put in a "write protect" mode so that no data can be written to the drive. This insures that the original source data is not altered in any way.

Once the cloning process is complete, the original drives you sent in are set off to the side and are no longer touched. The actual recovery process is performed on the cloned copies, so nothing that is done during recovery can make the situation worse. After the drives are cloned, they will be loaded into an emmulator and destriped. Destriping is like taking the scattered pieces of a puzzle and putting them together neatly. Simply stated, destriping is taking the data scattered among the multiple drives that make up array and placing it onto a single destination drive. From there we have a single drive in which we can complete what we would consider to be a "normal" recovery. We can complete this process even at the multi-terrabyte level. If the damage to the stripe is not too severe, in most cases a complete rebuild of the directory structure and all associated data can be completed.

As mentioned earlier, RAID data recovery can be expensive. Depending on the company you contact the prices can vary considerably. Typically a RAID recovery can be priced anywhere from $ 800 to $ 3,000 per drive. A number of factors influence the cost, such as RAID type, file system, total size, situation of failure, etc. Many times attempt fees and assessment fees are charged if the data is unrecoverable. This is understandable due to the amount of time and resources required to perform a single RAID recovery. However, in most cases the costs involved in recovering the data are not even 1% of the data's overall value. If you are reading this article and you have not suffered a RAID failure, what are you waiting for? Back up your data NOW.

    I’m 14 and I got this after smoking weed and it hasn’t disappeared for 3 weeks

  • Chi_ Sandcrackers May 11, 2018 at 8:56 pm this is what it's like. It's one of the earliest childhood memories I have and also the only way I can describe it

  • Treisutetreizeci sitrei May 11, 2018 at 8:56 pm

    thank you for this video, really

  • Lexi J May 11, 2018 at 8:56 pm

    I'm so glad I finally found the answer to what I experienced. I overcame it after 3 or 4 months in 2012 following a panic attack and I'm not sure how, but I thought about it all the time trying to find an answer. At the time I Thought it was just an anxiety disorder and used some mind exercises I researched about online, and eventually I accepted that it was something I was going to have to live with. Once I accepted it, I began to feel more at peace about the fact that my life was like that, and it eventually just faded away and I had feelings again. I fell back into my body. But of course it was still a horrible experience, and I just hoped that one day I would feel normal again.

  • Manish Kumar Singh May 11, 2018 at 8:56 pm

    i used to have this a lot when i was a kid, when the school went over time
    i used to feel my mind was driving my body….. like one does a car.
    my voice used to be perceived weird.
    I kinda felt invincible, not afraid to get Hurt or injured and used to bounce around like crazy.

    I generally enjoyed it, although it wouldn't be easy to study in that form.

  • Anda Lightworker May 11, 2018 at 8:56 pm

    I think I'm going crazy. Too scared that I'll get locked up if I get help.

  • Berend Konings May 11, 2018 at 8:56 pm

    I feel a whole less alone right now, thank you so much

  • Cristian Andrei Sebastian May 11, 2018 at 8:56 pm

    NeverFearAnything Yes. And it's like living a dream. My familiar faces are not familiar anymore. It's really strange. I started to identify again with my body, but this derealization looks to persist. As I said, I can't focus at school because my mind is thinking only at this situation. Have I just to ignore this symptoms? If I'm going on with my life, my recovery will be faster? Also, I don't have sexual appetite, to be honest. It's such a depression due this derealization and I need someone to help me.

  • Moses Kangeja May 11, 2018 at 8:56 pm

    I think I wouldn't have survived in high school if I had go through it then . lucky it came after my last year . college I plan to go when I am 100%better and better outlook 9n life

  • David Lopez May 11, 2018 at 8:56 pm

    Very helpful. I get what your saying. I’m not recovered. I am very bad. I feel like a robot with the occasional blip of emotion. Your video makes me hopeful

  • Christian Garcia May 11, 2018 at 8:56 pm

    Hi all

    I used to watch this channel and I think it was super helpful. A few years ago, I experienced depersonalization and as you know (if you're watching this, you probably have it) it's a living hell.

    It took years for me finally finish my book. I have it as a direct publish on Amazon. It's $1 (because Amazon requires a minimum cost), but I don't care to make money. I just hope to help people. If you have the chance, please have a look. I hope it gives insight and hope to those who need it. Thanks.

    YOU cannot alter the nature of REALITY, it has always been like this FOREVER. Letting a small stimuli in your life to cripple you is IMPOSSIBLE. YOU ARE THE MASTER OF YOUR OWN FATE, CAPTIAN OF YOUR OWN SOUL. Remember, THE ONLY LIMITATIONS WE SET ARE IN OUR OWN MINDS. The MIND could be the last one to harm you or cause you pain. In my opinion it LOVES you, so to speak. I got my DP from a panic attack after smoking too much weed for the first time. Every second was a constant struggle. It was as if I was watching over myself and the thought that I was watching over myself would drive me insane. I dont know much but this might help, it soothes me though. Instead of TRYING to RECOVER from DP start BELIEVING "YOU ARE RECOVERING". "YOU ARE GETTING BETTER EVERY FUCKING SECOND." It isn't nothing more but an EXPERIENCE. So if you are like me; viewing in the grand scheme of things, viewing it as nothing more but a BAD TIME would help. Also try talking to yourself (mind). Though it might sound counter-revolutionary. We've always been doing that don't we? What FREAKED me out was that I AM NOT THE SAME PERSON I USED TO BE. YOU ARE NORMAL, YOU HAVEN'T CHANGED. YOU STILL ENJOY YOUR LIFE. YOUR VOICE IS THE SAME. YOU ARE THE SAME. RELAX.

    I've overcome this and wouldn't wish it on my worse enemy. These videos make the syptoms come back and I can relate 100%

  • Hannes De Preter May 11, 2018 at 8:56 pm

    he explains in the way i have felt exactly in certain situations just like i'm watching myself in a movie and i don't constantly have this for me it mostly gets triggerd when i'm under the influence of alchohol so i'm considering quitting but then again i don't know if that's something i would do so yeah what do i do

  • Good Kitty May 11, 2018 at 8:56 pm

    i think it's dissociation…the brain not wanting you to fully engage as means to protect you. the part of you that's been emotionally traumatized by whatever is "watching" for trigers to protect you…i think the needing constant stimulation, something i experience myself, means you are out of hte body and within in the mind. it's what i'm working on right now, i mean whatever that even means

  • Logic May 11, 2018 at 8:56 pm

    Staying away from new agers, it's not spiritual…. it's just anxiety and trauma. , quiting sugar, staying off computer screens 👍🏻

    Depersonalisation is weird and scary so thanks for sharing and making sufferers feel less panicked by it.
    I read somewhere that CFS/ME would have been called a 'nervous breakdown' about 30yrs ago.
    Depersonalisation usually occurs after trauma to allow the physical/emotional process to process when it is safer to do so. It is a survival mechanism. Weird when it happens but shows the brain is protecting you.
    Keep doing these videos they are so helpful!

  • Amnesia May 11, 2018 at 8:56 pm

    Its been a long 1 year dream, and its still going on 24/7

  • alain rosso May 11, 2018 at 8:56 pm

    i lived with this for many years and it went away for a while, after my mum died it happened again i 'm tired…

  • Mike Dryson May 11, 2018 at 8:56 pm

    It feels like im stoned all the time and my brain is sleeping

  • Idil mohammed May 11, 2018 at 8:56 pm

    Thank you for sharing! This video was really helpful!!

  • Allen Esparza May 11, 2018 at 8:56 pm

    I am in the middle of my dp/dr literally while i type this paragraph … when it first hit me I went straight to the ER and got tons of tests done and the docs said absolutely nothing is wrong with me, that was almost exactly 2 weeks ago. I choose to love myself and address my trauma issues accordingly. I am 34 years old and to my knowledge I have didnt have dp/dr growing up. I was an accomplished athlete growing up and am very successful in my career. This scary and terrifying disease can hit anybody. Please be strong and learn to love yourself and dont let it beat you. Be strong. Im open to anybody that wants to talk to me.

  • Ludwig Störholt May 11, 2018 at 8:56 pm

    The thing you said about not having any standards for yourself, not thinking that you should be or react in a certain way, I believe is very important. Because if you are not tied to an image of how you should be, you won't disappoint yourself by not living up to those standards which means less anxiety. But easier said than done perhaps, as with many things.

  • Secret Girl May 11, 2018 at 8:56 pm

    Thank you. i feel so relieved that i am not alone.i also have some another tips: try to surround yourself with positive people and whenever you don't experience it, just don't think about it because you'll end up in the same situation. plus, i realized that i usually feel like this when i am alone, so try spending time with people your family and friends. or try to help others which makes you feel proud and helps you focus on something else as well so that you can be yourself again,right? i hope it helped you…

  • Evasionᴭᴺ May 11, 2018 at 8:56 pm

    I feel like the internet and video games raising people more than their own parents and all the shit in this world right now makes a lot of us feel like just a pair of eyes. Everyone wants you to look at something these days, random people want you to look at pictures of them for no reason all day. This world of technology is breeding lots of mentally ill children I'll tell you that much.

  • Laila 333 May 11, 2018 at 8:56 pm

    I feel like for 4 years I’ve been in a dream. I can’t focus at all, but I’m somehow conscious of what I’m doing. I’m typing this now, but I don’t know how. Because I’m in a dream. It’s the same when socialising; like I’m not aware of what they’re talking about. But I somehow reply with the right things. I can’t snap out of it though.

  • Case Holderfield May 11, 2018 at 8:56 pm

    It's demonic

  • Robbie Jr May 11, 2018 at 8:56 pm

    Yes i would just say random shit expecting it to come out different.

  • Cherrylover134 · May 11, 2018 at 8:56 pm

    It feels like im spectating

  • Deborah Simonson May 11, 2018 at 8:56 pm

    Really glad you were able to come out it DP, I have been doing all the good things you said to do. I have had it for over 30 years 24/7. Did not do drugs, not have panic, but do get stressed out easy and have a lot of stress in life, husband and son have aspergers, so looking after them is a lot of work. Weird how any person I've seen to deal with DP doesn't know anything about it. I tried all the drugs for DP years ago and nothing helped so I stopped all. Am now trying eating vegan to see if this might help. So happy for you, nice to know others have made it out.

  • fkz May 11, 2018 at 8:56 pm

  • incognitooo To Crasis Fan Page May 11, 2018 at 8:56 pm

  • Nick Cafarelli May 11, 2018 at 8:56 pm

    Yea, you become more appreciative.

  • World Mania May 11, 2018 at 8:56 pm

    I feel like i m in dream.

  • Gemini Genie May 11, 2018 at 8:56 pm

    I have it too brother!

  • Issac and carver May 11, 2018 at 8:56 pm

    Thank you. Your video helped me calm down and its good to know other people are going through what i am going through too. Its like the movie Being John Malchovich.
