Data Recovered From Space Shuttle Columbia HDD
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 will probably never use the term "crash" to describe a hard drive failure again.
I'll bet Ontrack made a fortune off of this recovery, too.
I might know what I'm talkin' about, but then again, this is Slashdot...
Their server is shooting flames as I type this, but they have the technology to recover their site!
Wow! They recovered 400MB of data when all they had to work with was "500 Internal Server Error"?! Unbelievable!!!
So someone put together a story on spectacular hard disk failure, space shuttle, physic experiments and heroic success, and decided to host this on anything less than an industrial-strength web server? The only thing that could have made for a quicker or larger slashdotting would be if somehow it also involved big guns and Natalie Portman (with hot grits, petrified).
Seriously people. Show some foresight here. At least the editors should have shown some mercy.
Soooo.... anyone got a coral cache of it?
Those who can, do. Those who can't, sue.
I think when you're intending to launch something into space using a couple of giant rockets, you might be concerned about vibration shaking normal bolts loose.
As for the condition of the drive, it's hard to say. The exterior was obviously fried, but it was still basically drive-shaped, and from the picture it's impossible to say how damaged the platters were. If the outside was messed up but the platters were still intact, I would think recovery would be fairly simple. Would have been nice to include a picture of the interior of the drive, or maybe even multiple pictures as they took it apart.

Great, so it was you that finished off the server. gatzke effect. Not really got the same ring to it.
Almost looks like the site is denying visits when the referer is slashdot.org. With the below method, I was able to read the full article with no problems.
To get in, simply copy the link in the story into a new browser window and hit enter to come into the site with no referers.
Hope this helps

Data recovered from Seagate drive in Columbia shuttle disaster
posted on 06 May 2008 20:05
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.

Now look what you've done. Wasn't it bad enough the shuttle burned up? Now you've gone and burned up the server trying to show us pictures of the mangled hard drive from the burned up shuttle.

I'm amazed that it's still in one piece and recognizable.
I've always been skeptical when a hard drive's specs mention being able to handle 300 g's. Looks like they aren't kidding.
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?

You call THIS "recovered"??? More like "Houston,we have a problem ..."

If this experiment was on Columbia, why is the image called "Challenger_drive.jpg"?
Challenger was many years earlier...

I'd say that's the part that makes this impressive. Re-entry is known to be pretty darn warm. And heat will scatter magnetic domains. Heat up a magnet - it's not a magnet anymore.
Either this HD was in the center of a ball of stuff and didn't get very hot, or Seagate has some seriously awesome engineering going on.

rediculous.
For anyone curious about the actual experiment whose data was recovered:
... 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."
The abstract for the science experiment is at http://link.aps.org/abstract/PRE/v77/e041116 (or in the table of contents issue is http://scitation.aip.org/dbt/dbt.jsp?KEY=PLEEE8&Volume=77&Issue=4 ).
"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
"Product warranty is void if any seal or label is removed, or if drive experiences shock in excess of 350 Gs"
"I'm a well-wisher, in that I don't wish you any specific harm."
That "First post recovered !" business was really a debug string literal that crept in at one point.
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.
How weak is that?

Did anyone else notice that the drive got so hot that the head controller IC was completely de-soldered. Just goes to show that if you want a hard drive destroyed you should have it shredded.

I worked with hall-effect devices which we used to build tensiometers in the textiles industry. One of the problems we had was loss of sensitivity over time. The service lifetime of a unit was a year or so before it was returned to me for rebuild and recalibration. The reason was that the unit was used in an industrial setting with lots of vibration and noise. The magnets lost strength.
All I had to do in many cases was to swap in a new set of magnets (and send the old ones out to be remagnetized). Then there were the clients that would turn the current up to compensate for the demagnetizing. They sent theirs back for a smoke refill after the smoke got out.
