Getting extensive drive info for data recovery

i want to build a java drive fat file checker so that before each exit/reboot...the files are saved on removable disk keeping the partition information in case of a virus attact that would destroy these fat files.
The problem...is that it has been too long since i have been doing java...i need to get pointed in the right direction for this project.
If anyone could link me to file or drive object models and attributes....as well as any knowledge on drive mapping and drive info gathering would be very welcomed.
Thanks for a great forum guys!
LA

i did notice this java class...although i read that it does not read extended partition information (ie...cluster sizes, starting positions and ending position, pointer locations etc. )
....is there not some wrapper class or something that was created for just this purpose?

  • Hard drive failure - options for data recovery and AppleCare coverage

    I have been handed a relative's 12 month old MacBook Pro with a factory-installed 500GB hard drive which appears to have failed. When attempting to boot the MacBook I am met with the classic clicking and grating noise which I know is a tell-tale sign of hard drive failure. The drive will not boot and I am shown the question mark folder icon, indicating that the operating system cannot be found. Have booted into internet recovery mode, Disk Utility appears to have found no sign of the hard drive's existence and shows none of its partitions. I have attempted putting the MacBook into FW target-mode and mounting the disk from another laptop, but to no avail; while it will go into target mode the drive simply isn't visible. The SATA connection to the drive is definitely OK - I have tested with another 2.5 inch hard drive which showed up fine in Disk Utility and was bootable. Have run Apple Hardware Test/Diagnostics but this returned no errors. It seems like a pretty clear cut case of drive failure.
    I put this all to the relative whose laptop this is and asked them whether the MacBook had been dropped recently, explaining to them that this is one of the likeliest causes for such sudden failure. Sheepishly they admitted that they had indeed dropped it, although not from too great a distance and onto a carpeted floor. Apparently in the days immediately after the shock the hard drive continued to boot but the system was very slow and beset by spinning beech ball hangups. It is only in the last few days that the hard drive has become completely unbootable, and seemingly unreachable.
    I have two questions that I would be grateful for some help with.
    Firstly, is there any possibility of recovering data from this drive without going to a data recovery specialist? The user did have backups of most important data, but some recently imported photos were not backed up. Is it any use me trying any third-party data recovery software utilities, bearing in mind that I can't even mount the drive in target mode?
    Second, the MacBook is still covered by the extended AppleCare warranty for the next two years. Is it worth my relative's while making a Genius Bar appointment to see whether Apple would replace this drive for free, given that the damage was most likely user-inflicted? Is there any chance that this sudden failure could be unrelated to the drop the MacBook suffered the other day - perhaps just a result of the 'normal' failure rate? I am more than happy to exchange the drive for a new one myself and my relative is happy to pay for the new part (I was amazed at how cheap hard drives are now), but would we be better off trying an Apple Store? My prediction would be that while we might get lucky and have an obliging genius who agrees to swap the drive without asking too many questions, we could also have one who concludes the damage is not covered by the warranty and insists on charging for the new hard drive (at a mark-up I assume) and labour.
    Any thoughts about these two issues or the hard drive failure more generally are very welcome. Thanks.

    1, Data recovery software is your only alternative if there is no backup. It may or may not be able to revoker anything from that hard drive. If it does then the only other choice is to go to a data recovery service. If have to go that route expect to pay for it, like $$$$.
    2, Yes. They will at least tell him what the problem is and the cost if any to fix. There is a good chance they will fix it for nothing and only charge for data recovery if they can do it.

  • Disk Warrior didn't work for data recovery. Any suggestions? After recovery, what's the best SSD for 13"MBPro?

    My hard drive decided to quit after only 22 months! Some files were backed up but my current photo albums were not. That's all I really need, I don't care about all the other junk. I've tried booting from the Disk Warrior cd, which Apple Genuis Bar suggested since they don't do data recovery. Fortunately, I got the cd from my brother or I would've paid $99 and it didn't help at all.
    So it there another way I can do this myself or should I just bring it to Fry's for $149?
    Another question would be, after I recover the files, I'd like to upgrade my MacBook Pro 13 to a Solid State drive. I know I need a 2.5" SATA, but which brand/size is good for a $200-$300 budget?
    Thanks for your time.

    Thank you Sig for the information. Unfortunately, I ended up leaving my computer at Frys for Data Recovery.  They have the best guarantee around since they can refund $115 of $149 if they couldn't retrieve any data. This was better than other services of $125/hr whether they could or could not get any data recovered. I didn't want to spend $99 and DataRescue couldn't even run.
    I meant Disk Warrior was recommended by Apple Genius Bar to access my hard drive that crashed. They said it could "fix" it or at least power up so I can then retrieve my data. It couldn't find the hard drive. It just looped for 5-10minutes, which stated that if this was the case, the hard drive could not be "fixed" or accessed..replacement is needed.
    Now I'm in the market for hard drive or solid state hd.

  • I purchased the Logitech F310 game controller for my 2011 MacBook Pro. How do I get the driver installed for it. The Disk that came with the controller is a mini disk and will not insert into my laptop.

    I purchased the Logitech F310 game controller for my 2011 MacBook Pro. How do I get the driver installed for it. The Disk that came with the controller is a mini disk and will not insert into my laptop.

    May not make a difference anyway. The Logitech support site does not show drivers for Mac OS for the F310:
    http://www.logitech.com/en-us/support/gamepad-f310?crid=411
    I'd contact their support to find out if there is a Mac driver available, and if they can either give you a web link to get it, e-mail you the software, or snail-mail you a standard-size disk with the drivers.

  • JDBC Thin Driver Support for Data Encryption and Integrity

    Hello JDev Team,
    I am trying to implement JDBC Thin Driver Support for Data Encryption and Integrity.
    It works fine with java.sql.Connection and java.util.Properties like in the following code:
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    Properties props = new Properties();
    int level = AnoServices.REQUIRED;
    props.put("oracle.net.encryption_client", Service.getLevelString(level));
    props.put("oracle.net.encryption_types_client", "( RC4_40 )");
    props.put("oracle.net.crypto_checksum_client",Service.getLevelString(level));
    props.put("oracle.net.crypto_checksum_types_client", "( MD5 )");
    Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:main", props);
    etc...
    But I am developing an application with InfoSwing components and it has a different way to connect to Oracle database using oracle.dacf.dataset.connections.Connection, like this:
    sessionInfo1.setAppModuleInfo(new ModuleInfo("bc", "BcModule"));
    sessionInfo1.setConnectionInfo(new LocalConnection("JDBCThin"));
    sessionInfo1.publishSession();
    My question is:
    Is there any way to implement DataEncryption and Integrity into this type of connection?
    Thanks a lot in advance.

    Victor,
    No, you can't do this from DAC, but I've been discussing it with the developer, and we both think this capability would be useful to have, so I've logged it as an enhancement request.
    I do have a question for you. Once you've made the JDBC connection, do you need access to the Connection object afterwards? We're thinking of how the change could be implemented, and one way would be to allow you to pass in a Properties object when creating your own NamedConnection.
    Thanks

  • External drive won't mount- which software is best for data recovery?

    Hi,
    My external OWC drive won't mount to the desktop. It is visible in Disc Utility, but can't be manually mounted from there. Verify and Repair disk functions state that the disk appears ok (log below):
    Verify and Repair volume “OWC Mercury Elite AL Pro mini”
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking multi-linked files.
    Checking Catalog hierarchy.
    Checking Extended Attributes file.
    Checking volume bitmap.
    Checking volume information.
    The volume OWC Mercury Elite AL Pro mini appears to be OK.
    Drive lights up and spins. No weird sounds, just won't mount.
    Not everything on the disc was backed up before the problem occurred. It's still under warranty with OWC, but I'd like to attempt to recover the data before sending it in for repair/replacement. The OWC tech on the phone said he's never seen this specific problem with this drive.
    I'm thinking Data Rescue 3 would be the best software to try, but does anyone know of any other options to try first?
    Thanks!

    JohnDoe2009
    I concur with the previous poster that if Disk Utility found no problems running TechTool Pro, Drive Genius or Disk Warrior might get it going. If you don't have any of those you could try
    • Download and install Applejack
    • Restart computer holding down Command + S
    • When Command line comes up type in
    +applejack AUTO+
    Let is run all five functions.
    In terms of Data Recovery
    DataRescue 3
    Virtual Lab
    FileSalvage
    are all excellent tools, and all offer a demo version.
    Dr. Smoke's FAQ Data Recovery offers excellent tips on how to do it.
    Good luck.

  • Finding parts to repair drive for data recovery

    I have had a hard drive on a Powerbook 12" go down. I bought it in 2004, and it seems that the data recovery company I have sent it to are having problems sourcing another drive so they use parts to repair it and recover the data. They seem top have gone to lengths to try and source what they need, but I thought the discussion forum here might have some experience with this. The disk is Fujitsu Model mht2060at, the original 60Gb disk that was in the laptop. It now lives(?) outside of the laptop which has had a replacement disk fitted...
    ...Any suggestions would be appreciated.

    Well, as far as they have said, they need to find comparable donor parts to repair the disk in order to recover the data, and so far they have not, in spite of an extensive search.
    Also, they were not quoting cheap either. They have given me the option of simply having the drive returned, which I am inclined to accept, or else go and collect it in person. They have after all had 2 months. I think my real problem has been that at the start I was really hesitant in choosing a company as I could verify the quality or value of any of them: I took quite a while to pick one, and I picked this one finally after asking around, and finding there wasn't really anyone who had a better idea than myself.
    Now I am in the position of potentially being back where I started, 1 down, all the rest to go, with a carriage fee every time I send it back out, and with the prospect of losing the disk in transit, or stumbling across a completely rogue operation.
    Here I am therefore, needing to find a company with an established reputation...
    ... if there are some testimonials for the company you suggest from other apple users, I would really app[reciate them. I know it isn't cheap. I need to be convinced on the next choice though before I part with another bean, and I would appreciate anyone with advice on what process may take place, and what I should reasonably expect to pay...

  • Need info about data recovery services

    My main hard drive on my Mac G5 crashed on Saturday, and I'm sending it to Drive Savers today. My question concerns security and confidentiality. I have some files on the drive that I would prefer that no one looks at. To what extent, if any, do these places open and look at the contents of individual files? I can't imagine they look at everything. A typical drive like this will have 100s of thousands if not millions of files.
    Thanks for any info.

    Hi mrsaxde-
    The sad reality is that once you hand over your data to anybody you really have no assurance that your files will not be looked at.
    Most likely I would suppose that data-recovery services would not want to get a bad reputation as "the company that looks through your personal data", or something similar, and would be sensitive to such things.
    I would suggest a Google search of that recovery company and see what folks might have to say.
    I have all of my stuff backed u in triplicate, generally due to paranoia about things like this happening. This is unfortunately an expensive and scary lesson in support of a proper backup routine.
    Luck-

  • Help! hard drive failure and data recovery

    I am a happy PC-traitor who has been using my Macbook successfully for over a year now. I love the Mac.
    Until now.
    Last night, while downloading torrents onto my computer, it froze. I restarted. A blinking folder with a question mark was displayed. I tried resetting the PRAM. Disk Utility does not see my hard drive, so I cannot attempt to repair it.
    In short, I think it's dead.
    Disk recovery is so incredibly expensive! Can I stick the hard drive into an external housing and access the data via Firewire? Can I freeze it overnight? I'm desperate! I can't afford a data recovery service. Help!

    If she's dead, she's dead. Could be a loose cable. If you boot from a DVD and DU can;t see the HD, that's usually a really bad sign.
    If you are comfortable removing it, you can try something like
    http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/
    which will allow you to mount just about any HD via USB.
    You can try stuff like
    http://www.macintosh-data-recovery.com/download-mac-data-recovery.php
    http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1
    http://prosofteng.com/products/data_rescue.php
    And then there's DiskWarrior and TechTool.
    Some of these may see HD's that won't mount and allow you to recover data.
    Others may chime in with more detailed experiences.

  • Time Machine drive files after data recovery.....permissions problem?

    Client had a hard drive crash, and then turned out her Time Machine drive was bad. We ran a data recovery on the Time Machine drive, which produced about 40GB of disk images...12 in all. There is a very promising image which shows the user folders, and we can click on hers and see her folders. BUT...when we try to open Documents, we get a message that
    "Item "Documents" is in use by Mac OS X and cannot be opened"
    Would there be an override of permissions or some such available to take a peek inside and hopefully pull files?
    Thanks to all in advance.

  • Best software for data recovery

    Help please!  I had my iphoto library in my Google Drive folder.  I didn't realize it was there and so I put my Google Drive in the trash and now I don't have my photos.  Does anyone know of any low cost data recovery software?  Thanks!

    General File Recovery
    If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

  • Hard drive info for missing 2 GB space

    Dear Mac users,
    I recently bought a mac book which I am very excited about. Being a PC user for a long time I like to have control over the hard disk space which somehow is clear with Windows XP.
    My first observation with my new Mac book is the folder size and its location. When I clicked Get Info for the Macintosh HD it showed 17.22 GB as total used space. Then I selected each folder inside the Macintosh HD which sum up to become 15.2 GB. Now I am surprised where does the 2.02 GB go? I believe its some hidden files. Could someone point me to the direction where I can get more info about this? I want to know where files are stored and which files are very important for mac OS. Will look forward for your suggestions.
    Thank you.
