    Very unlikely. A forensic data-recovery specialist *might* be able to do it, but it would cost a lot.

    They could do it, the actual platters would be fine, its the circuitry that is ruined.
    If you decide to go this route they charge $60-180 per hour depennding on your area, and this should be no more then an hour hour or two. All you would really have to do is change the casing are firmware out.

    dont know if you know or not, but arent the platters hermetically sealed? if so I'm assuming that that would mean waterproof

    The HDA assembly is NOT hermetically sealed, there is a vent to allow pressure to equalize, and a small screen of some sort that keeps the big pieces out. :) I suspect that a drive that was submerged for several days is toast, and so it the data.

    As far as getting a data recovery service to do this in a couple of hours, good luck on that quest, I really doubt it'll be nearly that cheap. :rolleyes: I also think the probability of success is very low. If you actually got the disk to spin after it was submerged for that long, it's pretty difficult for me to believe that the heads haven't really done a job on the platters since they're undoubtedly wet...

    I have heard some amazing stories about what those recovery companies can do. But All i have ever heard is it's expensive. Just recently the makers of Penny Arcade (www.penny-arcade.com) had a hard drive fry and it was salvagable but expensive.

    I guess it comes down to if you had any data on there worth what they are gonna make you pay if they can salvage it.

    So you've opened it up? If so you've just lowered your chances of data recovery even more. And if its been run then I would say its almost completely hopeless. Either way your only possible hope is a quality professional data recovery company and I wouldn't be surprised if they say they can't do it. Real life is not like on C.S.I. where they do some magic and recovery all hidden secrets in a few minutes.

    Okay so this question really bugged me, so I asked a friend of mine who does(or did) data recovery.
    According to him, yes the drive is recoverable.
    The platters are sealed, because even one grrain of Dust can destroy the platter if it gets between the head and the disk.
    According to him what would be done is they would take the platters out and clean them, then bring them into a clean room where they could scan the platters!
    So at least now we know it is possible.

    The platters are not sealed, if you simply take any hard disk that has crapped out apart, you'll see that this is true. There is a filter to keep dust particles from getting in, but there is an air vent to equalize the pressure inside the case. I have my "display model" old WD to show people the inside of a drive when I'm asked, and there's a 1/8" x 1/2" slot where the little filter used to fit, it was discarded long ago.

    no, water means circuitry is ruined, the platters are fine unless you managed to get the disks to spin after the flood, then you could have ruined the surface of the platters.

    a long time ago, my gameboy color (old) fell in water and stopped working, a week later, i tried it and it worked again


    ps that hole on the hard drive doesnt lead right to the platters

    if a single peice of dust falls on the platter, then it will lose a lot of data.


    try running the hard drive after a week or 2 and see if it works.

    getting a place to recover data, the price range goes around $3000-over one hundred thousand dollars

    P.P.S. On the WD that I have sitting on my workbench, that little hole does indeed lead right to the platters.

    In addition, he's already opened the drive up and seen the water stains on the platters, which would certainly indicate to me that his is not sealed...

    If you drop a hard disk in water and fetch it out right away, it probably won't inundate the platters. However, if you leave it under water for a day or two, the drive won't survive.

    I have recovered a laptop that was dropped into a swimming pool, and immediately removed. It was in the water for perhaps 30-40 seconds, and totally submerged. In that case, the water didn't have time to seep into the hard disk, and it survived after disassembly and drying. It also took several weeks before it would function again.
