Data Recovered From Space Shuttle Columbia HDD

Posted by timothy on Wed May 07, 2008 02:12 PM
from the gary-sinise-was-not-involved dept.
WmHBlair writes "Data recovered from a 400MB Seagate hard drive carried on the Space Shuttle Columbia has been used to complete a physics experiment performed on the mission in space. The Johnson Space Center sent the recovered drive to Kroll Ontrack in Minneapolis, Minnesota. Considering the shape the drive was in (see picture in the linked article), it could indeed qualify for the 'most amazing disk data recovery ever.'" Update: 05/08 12:51 GMT by T : Reader lucas123 points out a piece at Computerworld with a series of photos of the recovered drive.

    Data recovery has come a long way, keep this in mind when not using proper deletion techniques! Would have been nice to see a picture of the HDD though, to get a full understanding of the recovery.

      I've used OnTrack numerous times and they really know their stuff. I know there are other recovery services out there but these folks have earned my business.

      Basically, you pay a bench fee to get the drive examined, and then they send you the costs for recovery - for a desktop HD $500-$1500 depending on the problem. The cool part is that they send you a manifest of the recoverable files/directories so you can make an informed decision.

      And they _can_ perform miracles. Including dealing with bent platters. Just depends on what you want to pay.

      I must say it's been a great instructional tool for people who've neglected backups. They become wild operational militants after these episodes.

      Just remember that the ONLY way to ensure data cannot be recovered on a HD is to raise the drive temp past the Curie Point for the magnetics. (A charcoal BBQ works really well for this. Just pull the electronics and wrap the drive in heavy foil unless you like the smell of roasted phenolic.)

      Even if you "format" a drive it means that the waveforms coming off the heads can be interpreted as a certain, predictable value - but also remember that at root, it's an analog system and so artifacts from the prior contents are around, it's just a question of finding and interpreting them... That's why the DoD and other "erase" things are so comprehensive. Trying to obliterate all artifacts.

        There are a number of standards for secure deletion of magnetic media, but basically writing over it a few times with a random pattern should be sufficient. A lot of people claim that the Gutmann method is superior but that was based on an older encoding scheme that presupposed you knew about the physical layout of the data -- modern drives are permitted to shuffle your data however they want (e.g. sectors can be mapped arbitrarily to the physical platters). Gutmann himself no longer recommend his eponymous method:

        In the time since this paper was published, some people have treated the 35-pass overwrite technique described in it more as a kind of voodoo incantation to banish evil spirits than the result of a technical analysis of drive encoding techniques. As a result, they advocate applying the voodoo to PRML and EPRML drives even though it will have no more effect than a simple scrubbing with random data. In fact performing the full 35-pass overwrite is pointless for any drive since it targets a blend of scenarios involving all types of (normally-used) encoding technology, which covers everything back to 30+-year-old MFM methods (if you don't understand that statement, re-read the paper). If you're using a drive which uses encoding technology X, you only need to perform the passes specific to X, and you never need to perform all 35 passes. For any modern PRML/EPRML drive, a few passes of random scrubbing is the best you can do. As the paper says, "A good scrubbing with random data will do about as well as can be expected". This was true in 1996, and is still true now.

          I've got a friend/co-worker/gun-nut who never returns a drive with his data on it. Work gets laptops back, sans drives. He takes them out to the range with a high-powered rifle and puts rounds thru them.

          Me, I just use OS-X's write-random 7-times. But if blocks got remapped because of io-errors in the drive, that might be enough for the truely paranoid. If I were that, I'd use my oxy-acetylene torch and just melt the platters to slag, after pulling the magnets out to play with.

        Ontrack has been doing this type of recovery for years. A couple of times I have asked for quotes, just to even look at the drive was like $1,000US. Can't remember how much it was per MB to retrieve the data. I know they have recovered data for machines lost in hurricane andrew, servers sitting in water for months. They were in Kuwait after the 91 gulf war recovering systems there. I think the only way to not have Ontrack recover a drive is to literally melt the platters.

        "Actually, they probably did it for next to nothing, anticipating all the free press coverage they would get. "

        Don't count on it. First off, they probably didn't even know if they could recover the data. Second, they would have no way of knowing for sure that NASA would release the information about them providing the data recovery services. Third, they very likely wouldn't have known whether or not the data (if recovered) would be used for anything in the future. Fourth, there are very strict rules about government agencies doing business where they don't pay for services, especially with potentially classified data on the drives.

        I would bet very strongly that they got well paid for this recovery.

    Am I the only one who thinks that it's a little odd that they used a moving parts hard disk drive for such a paltry amount of data? (If it was solid state then it'd be a power of 2, not a round number). Surely even 2003stonauts could have managed to put together more than 400MBs in solid state, thus saving power, size and reliability?

      The experiment, and all the hardware, would have had to be tested and verified as viable for use in the experiment. That would have taken at least a year, if not longer.

      I would say it was likely the experiments exact hardware requirements were set in stone a year or two before launch. Flash drives are plentiful and reliable now, but may not have been deemed reliable enough at the time.

      When it comes to space, tried and tested older equipment is better. Just ask the Russians.

      For precisely the reliability issue you bring up - most anything on the shuttle has to go through > 8 years of reliability testing - before it can go up. sooo... 2003-8 = 1995. They probably could have gone with something better than 400MB's - but in 1995 did you have 1/2 gig flash storage devices? Hell in 1995 did you have 1/2 a gig of anything?

        Actually, the Challenger didn't blow up. The external tank collapsed due to the solid rocket motor burning through the external hydrogen tank. As the hydrogen tank collapsed, the mass of the shuttle was greatly reduced, which caused an acceleration of the entire vehicle assembly. That acceleration drove the remaining portion of the hydrogen tank into the oxygen tank causing it to also collapse. As the same time, the srb burned through it's rear attach point to the external tank, causing it to loose lateral stability. That instability allowed it to rotate (out of sync with the rest of the shuttle stack) which further weakened the external tank structure.

        As the external tank collapsed and the srb rotated, it rotated the shuttle so that it was no longer aligned with it's nose pointed towards the direction of travel. The aerodynamic forces became so extreme, that it overwhelmed the shuttle's structure.

        The shuttle was literally torn apart due to the aerodynamic forces. The explosion actually occurred after the collapse and breakup as the escaping oxygen and hydrogen ignited.

    For anyone curious about the actual experiment whose data was recovered:

    The abstract for the science experiment is at http://link.aps.org/abstract/PRE/v77/e041116 [aps.org] (or in the table of contents issue is http://scitation.aip.org/dbt/dbt.jsp?KEY=PLEEE8&Volume=77&Issue=4 [aip.org] ).

    "We measured shear thinning, a viscosity decrease ordinarily associated with complex liquids, near the critical point of xenon. The data span a wide range of reduced shear rate ... The measurements had a temperature resolution of 0.01 mK and were conducted in microgravity aboard the Space Shuttle Columbia to avoid the density stratification caused by Earth's gravity."

        Most amazing disk data recovery ever

        It was one of the most iconic and heart-stopping movie images of 2003: the Columbia Space Shuttle ignited, burning and crashing to earth in fragments.

        Now, amazingly, data from a hard drive recovered from the fragments has been used to complete a physics experiment - CXV-2 - that took place on the doomed Shuttle mission.

        Columbia's fragments were painstakingly and exhaustively collected. Amongst them was a 400MB Seagate hard drive which was in the sort of shape you think it would be in after being in an explosive fire and then hurled to earth from several miles up with a ferocious impact.

        The Johnson Space Centre workers analysing the shuttle crash sent it off the CVX-2 (Critical Viscosity of Xenon) experiment engineers, who sent it on to Kroll Ontrack in Minneapolis, Minnesota, to see if the data, any data, could be recovered. For researcher Robert Berg and his team it was the only hope, a terribly slim hope, of salvaging significant data from the experiment looking at Xenon gas flows in microgravity.

        The Kroll people managed to recover 90 percent or so of the 400MB of data from the drive with its cracked and burned casing. Now, a few years on, Berg and his team have analysed the data and reported the experiment and its results in the April edition of the Physical Review E journal. These showed that, rather liked whipped cream which changes from a fluid to a near-solid after being whipped or stirred vigorously, the gas Xenon change its viscosity from gas to liquid when similarly treated in very low gravity. The phenomenon of a sudden change in viscosity is called shear thinning.

        It was a highly complex experiment needing prologed and detailed analysis of the data on the hard drive to discover the shear thinning effect. But it, like the drive, was eventually found. So ends a twenty-year research project and in doing so helps bring to a finish the dreadful story of the Columbia Space Shuttle mission.

          Well, there was some sed, awk, a dash of emacs in batch mode, python, some xalan and xlst in there (to simplify things).

          The expected output was, or course "Hello, World".
          We're obviously going to have to port some of this to Mono. Probably get a more impressive stack trace out of it, too: the line count that wimpy java business didn't even make double digits.
