Problem with recovering data from Bit Locker enabled hard disk with bad sectors

Hi,
I have Lenovo T430 laptop with Windows 7 and Bit Locker enabled hard disk. While working I encountered blue screen error multiple times. After some time, the laptop stopped to boot by itself and started showing error 'A disk read write error has occurred.
Press Ctrl+Alt+Del to restart' message. I tried to connect the hard disk to a different PC as a secondary drive and tried to check the disk to recover the data. The 500 GB disk is showing as unallocated space and I am not sure how to recover the
data from the hard disk. Appreciate your help to recover the data from corrupted hard disk.
I used the Lenovo Diagnostics tools available in BIOS and it showed 48 bad sector errors on the hard disk. I also used Windows 7 CD and tried auto repair but it looks like it didn't do anything.
Thanks in advance!

Hi  SenneVL,
Since there are 48 bad sectors on your hard disk, this means the system can not boot any more, the data might not be restored in a normal way, you'd better turn to data restore company for help.

  • Recovering data from my windows external hard disk

    I have a unique bit of problem. Well, i used windows system 3 years back when i switched to mac. I saves all my data in my windows format hard drive. From there i used usb thumb drive to transfer to mac. Recently i found that my windows hard drive is not working properly and so some of very important data i can't retrieve. I tried that hard drive in my office pc and can't read any data.
    Is there any way i can retrieve data and bring to my mac formatted hard drive?

    When you attach your old external hard drive to the mac what happens?  Do the lights on the drive come on?  Do you hear and feel the drive "spin up"?  DO you get any type of message on the Mac?
    Your Mac can read the majority of external hard drive file systems that would have been used with Windows computers now and in the past (FAT or NTFS).  About the only thing that would not work is if that drive was either encrypted or used a very non-standard driver that was only available for Windows.
    Let us know exactly what happens when you first power up, and then attach your drive to the Mac.  Also, what make and model is the drive?

  • Recovering data from a newly formatted hard drive

    Has anyone had any experience with programs that recover data from a newly formatted hard drive?  There seem to be a lot of programs out there to do this, but, a) do they work, and b) which one worked best for you? 

    Ive had so and so success with a freeware utility called "Recuva"
    http://www.recuva.com/
    Its from the makers of CCleaner.

  • Recovering Data from A WD External Hard Drive

    I have an older IMAC 20 2007- Leopard 10.6 installed and running great. I have a 1tb WD hard Drive via FireWire and a 2tb hard drive via USB 2 as there is no Seta hook up on the IMAC. I also have a 500Gig WD external hard drive that has a lot of saved movies and programs on it. I Want to recover the movies on the 500 Gig. to the 2 tb or teh 1 tb hard drive. The problems is, when the IMAC recognizes the 500Gig Hard drive it will not copy the movies over as it says "they are in use and cannot be copied" OR the IMMAC will not recognize the 500Gig drive at all, it says the hard drive is not recognized. The movies were copied to that hard drive with the IMAC Why can I not recover them from the Hard Drive? I assume that the hard drive may be on its way out. Does anyone know how to recover those files? Mostly Movies MP3s and some programs. Thank you

    Install OS X for emergency use so you can do repairs and maintenance, on another drive.
    Some iMacs can, at least now, maybe retrofitted, have an eSATA controller added. Yes, shame there is no ExpressCard slot of native external SATA ports.
    USB2 is slow and terrible interface for today's drives, real need for USB3 drives.
    Tried Data Rescue 3 demo?
    How about a full volume clone operation with SuperDuper or TriBackup 5, or Carbon Copy Cloner?
    WD MyBook units can be Mac-unfriendly and trouble, there are Mac specific models of WD MyBook or there are other makes that do work, usually use the Oxford chip bridge to provide USB/FW/eSATA.
    Maybe there are errors with file system, data, or even the drive directory causing problems.
    Do the external drives have their own power supply? should.

    You don't have to change NTFS to FAT.
    Just install Paragon NTFS and you'll be able to transfer your data to your external HDD even if it is NTFS.

  • Need help with recovering data from a truecrypt HDD

    I have done something stupid, I have run fdisk on my truecrypt hdd by mistake, and created 2 new partition. the 1st one on 67mb and the 2sd for the rest of the hdd.
    Can someone plz help me with restoring the data? I am not really sure there to begin.

    Get testdisk.  I use Parted Magic to recover partitions with Testdisk.  So long as you can decrypt the resurrected partitions AND provided you have NOT written to those two partitions after they were fdisk'ed you should be able to recover from this mess.  I really recommend PartedMagic for this sort of thing only because it has a good interface and a lot of other tools in one place.
    Testdisk isn't hard to use and there are mini-tutorials out there if you're really stuck such as these links from our wiki:
    Testdisk and Photorec

  • Cannot open Microsoft Office after copying it across from external HD with recovered data from my broken macbook HD.

    I have recently had to replace the hard drive in my macbook pro. All the data has been recovered from my old one onto an external HD and I have copied over everything from this onto the new HD on my macbook. Everything is fine except for Microsoft Office (2011).
    Although I can see all the Microsoft Office programs in the Applications folder, I can't open any of them. It sort of tries, but then doesn't open. All my word, excel, etc documents have the little 'W' or 'X' in the icon and I can preview them, but it won't open.
    So far I have copied Office and Messenger into Applications, 'Microsoft' into Application Support, 'Microsoft' into Preferences, and the 'Microsoft-Userdata' into Documents.
    Have I missed something? I don't have the original CD or product key anymore so don't think I can completely reinstall.
    Thanks.

    Thanks for your help - I have now found the original product key (although still no disc!)  so is there any way now? After this, I'm giving up and just biting the bullet and buying it again, annoying!

  • Transferring data from ancient SCSI external hard disk to an iMac

    I have an old 60mb external SCSI hard drive - so old that when I got it 60mb was huge - that I used with an old Mac Classic. My wife then used it as a backup for a Quadra. Now we want to transfer all the stuff on it to an iMac (which runs 10.4). How do we do this?

    hillmore,
    More and more, the best suggestion is to find a user group in your area to make one time transfers. Where in the world is 'Carmen San Diego' or your iMac for that matter? Post back with a city and we might know of a resource near by.
    In the NW, Seattle has the best options. Just mentioned them here

  • Trying to Recover Data From Old Backup Exec Tapes

    I have been tasked with recovering data from an old Windows XP machine with an HP C1537A DDS3 tape drive.  The machine used Backup Exec to create the tapes.  In trying to recover the data I constantly get an error that says the data on the tape is inconsistent.  I tried to run the HP analysis utility but it said the error log of the drive was full and it would be necessary to do a firmware load to clear it.  I therefore loaded the lastest firmware.
    I ran the HP analysis utilities using one of the tapes as a scratch tape (to write over):
    Test 'DDS Drive Assessment Test' started on device 'HP C1537A' at address '6/0.0.0'
    Please reload your media. Do you wish to continue?
    |__ Analysis Results
        ||__ DDS Drive Assessment Test version V08.11.2006
        ||__ Device Analysis for DDS Drives
        ||__ Firmware rev 'L411' is up-to-date for 'C1537A' as of Wed May 25 19:00:00 2005.
        ||__ You appear to have used tapes not designed for this drive.
        ||__ Please use tapes that are compatible with your product.

        ||__ You appear to be using very old tapes not designed for this drive.
        ||__ Non-MRS tapes tapes have been inserted 3 times.
        ||__ There were 9 rules checked.
        ||__ Testing has completed and no problems were found.
    The tape that was used in the analysis was a maxlell HS-4/125s DDS3 tape -- the same type that was used to create the backup tapes. 
    Why does the drive think I am using "very old tapes not designed for this drive"?  The tapes were witten to by this drive.
    What is a "Non-MRS" tape?
    The end results appears to be that "no problems were found" but Backup Exec reports that the tapes have inconsistent data. 
    Any suggestions on how to make the tapes readable by Backup Exec would be appreciated.
    I am using Backup Exec 9.1 Rev 4691.  Please do not suggest using a later version as this is the latest version that (1) will run on a Windows XP Pro box and (2) that supports the tape drive.

    Saberman,
    Have you tried the Enterprise/Business forum for this?  I doubt anyone here on the consumer section will be able to help you with Tape Storage.
    Here is the link to the Tape section of the forum.

    Good luck.

  • How to recover data from a hard drive with bad blocks?

    An external hard drive, 4TB Iomega...connected via eSATA cable...had a power outage and the drive won't be read by OSX now.  (Yes, it was on a surge protector and no I did not have a backup.  I was actually preparing for the process of creating a backup when the power went out!)  Anyway, I have tried using Data Rescue 3 and DiskDrill to try and recover data from the drive.  I can recover the first 1/3 of the drive, but it ejects when either app tries to access the bad block.  Can anyone tell me how/what software to use to recover the data?  I know there are programs that will avoid the bad block but I've only found them for Windows.  Are there any that will do such a thing in Lion?  Any help will be appreciated...and no, I can not afford a data recovery service.  Trying to do this on my own.

    Basics of 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.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
    Also visit The XLab FAQs and read the FAQ on Data Recovery.

  • How do I recover data from my macbook pro with a disk that can't be repaired?

    I'm in need of a data recovery solution.  My Macbook pro (17") running OS X Mountain Lion won't boot and is stuck on the gray startup screen with the apple icon and spinning gear and disk utility states "Error: Utility can't repair this disk.  Back up as many of your files as possible, reformat the disk, and restore your backed-up files."  Unfortunately, I don't have a back up and don't know how to access or back up the data on my drive.  Mounting it to another computer as an external drive  via firewire did not work.  Does anyone know of any solutions to extract the data from my macbook pro hard drive before I reformat it?  Any help would be greatly appreciated.

    Hi there
    I really am sorry about your problem.  I have opened up my help centre and it too states '[...]back up as much of your data as possible, reformat the disk, reinstall OS X, and then restore your backed-up data'.  It then says: If you continue to have problems with your disk, it may be physically damaged and need to be replaced. 
    I just noticed it says reinstall OS X.  If it says this then this indicates a rather serious computing problem. 
    Help centre also states: If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. [The next step is the following] Check each file in the list of affected files. [added by me]
    A damage disk causes files to be corrupted.  Also you can repair a disk by deleting corrupt files (i.e. one can still use a damaged disk providing it has been repaired).  Disk Utility is able to help to repair corruption problems but not if your program files have become corrupted due to large-scale damaged disk. 
    I understand why you want to connect to another hard disk because you want to extract your files and I would probably do the same.  I am on a 13-inch Macbook Pro trying to solve your problem.

  • Problems with retrieving data from tables with 240 and more records

    Hi,
    I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
    I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
    First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
    I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
    I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
    So for the retrievals that hang I have something like:
    (3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
    (3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
    (3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
    (3260008): FETCH NEXT:(DBI_FETCHNEXT)
    and this is the last line,
    while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
    On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
    Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
    I will appreciate any comments/hints/help.
    Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.

  • Question about to recover data from windows essential 2012 (with raid0 or 1)with third party software !

    hi,
    I like to know if it is possible to install data recovery software on a extern harddisk ,and run it from there , just run  the  third party software in the memory of windows essential 2012 to recover data from its  harddisk  which has
    raid 0 or 1.
    if it is possible to install third party softare on extern harddisk or on usb stick on run it from there which steps I have to take ,or if there is some article about  it on windows website.
    how to install third party softwares on extern harddisk or usb stick on run it from there.

    Hi johan,
    Based on your description, I understand that you want to know how install a third-party software on an external
    harddisk or usb and then run this software from there. Regarding this issue, I suggest that you should contact with the third-party software support and confirm it. Since most programs use windows registry entries, and may rely on some .dll files. If all relevant
    auxiliary files and configurations of this software were installed in one directory tree, you may be able to install and run it on an external harddisk or usb.
    Hope this helps.
    Best regards,

  • My iphone 4 is dead with water damage. Is there a way to recover data from the dead phone.

    My iphone 4 is dead with water damage. Is there a way to recover data from the dead phone. Could any one help where exectly the memory chip (not RAM) resides in the phone. Is it on the motherboard or a seperate component in the phone?

    The iPhone's internal components are soldered together. There is no way to recover data from your phone if it refuses to power up.

  • How do I recover Apps Data from the iCloud on iPhone 4S with IOS 6.1?

    How do I recover Apps Data from the iCloud on iPhone 4S with IOS 6.1?

    You would have to restore to your entire iCloud backup, if you have one.  (The backup includes app data.)  Restoring to an iCloud backup has to be done in the initial setup process.  If you have any data on your phone now that is not in the backup that you want to save you'll need to do that first.  Then go to Settings>General>Reset and tap Erase All Content and Settings.  You will then go through the setup screens as you did when the phone was new. When given the option, choose Restore from iCloud Backup.  Be sure you are connected to wifi and your charger as this will take some time to finish.
