Hi

As I said before that I faced some problems with my Sata HDD (internal) ....
  • It showed ...segment unreadable in scan disk on start up
  • I couldn't access its folders while I was able to see them
  • I couldn't recover my data completely, from dos
    One guy told me that he can recover data if device manager is detecting it
    but he is asking for a big money
    Now My hdd is continuously on Disk Manager but its showing UN allocated disk
    As its not my main HDD and I am running my system quite comfortably on another HDD so I want to know that
    Can I recover my data myself, as He will do, What s/w can help me in this situation and what process I should follow.

    thanks

    Personally i use Disk Digger to recover files which is free with a limitiation of clicking yes to every single individual file, unless you get the paid version which does it all with one click. The nice thing about diskdigger is that you can recover files from a corrupted file system or from a hard drive that doesnt appear to have anything on it.

    Otherwise I would try HDat2 or disk genious, which you can get from either the ultimatebootcd(UBCD) or Hirens boot CD. Both are found on their websites for free because they are freeware. Disk Genious is good because you can attempt to recover the actual corrupted partition table and if it can recover it you may be able to use the hard drive again without data recovery.

    Best solution

    I would first determine whether the drive has physical problems.

    Try a comprehensive SMART diagnostic. Look for reallocated, pending, or uncorrectable sectors.

    HD Sentinel (DOS / Windows / Linux):

    HDDScan for Windows:
    http://hddscan.com/

    See this article for SMART info:
    http://en.wikipedia.org/wiki/S.M.A.R.T.

    If there are a large number of bad sectors, then you would be best advised to clone your drive using a utility that understands how to work around bad patches in the media.

    ddrescue and dd_rescue are two good freeware cloning tools.

    thanks for a helpful reply :hello: 

    I would download and try these s/w , But tell me as i can see it on disk manager and sometimes windows says found new hardware and tries to install driver for it and installs it successfully.

    But in these s/w how I can add my hdd(now I am not using it), I remember, when I was trying it with isobuster then it was not showing this disk.
    so how to add it in them?
    and as far as cloning in concern, do I need an another hdd of same volume?(as I don't have this time)

    One more question I want to ask, 4 years ago I recovered some pics from a formatted hdd but I couldn't get them in full size, I can see them in thumbnails but I can't see them in large size, so is there any way so I can increase their pixels?


    thanks

    try running R-studio of the drive (r-tt.com), its an excellent data recovery tool.

    For a sector-by-sector clone, you need a target drive that is at least as large as the source drive. I would clone your drive ASAP, before it gets much worse.

    Ddrescue can perform multipass cloning. It clones the easy sectors on the first pass, and attempts the more difficult ones on subsequent passes. It can also clone your drive in reverse, thereby disabling lookahead caching. It keeps a log, allowing it to resume after an interruption.

    dd_rescue: http://www.garloff.de/kurt/linux/ddrescue/
    ddrescue: http://www.gnu.org/software/ddrescue/ddrescue.html

    Comparison between ddrescue and dd_rescue:

    As for your thumbnails, you can resize them using your favourite image manipulation software (eg ACDsee, IrfanView), but you will not gain any resolution. That is, your resized image will look like a digital zoom, with chunky pixels.

    If you can see hdd continuously on Disk Manager then you can do recover all your data & files your self, you don't :non:  need to go to that person only you need an efficient data recovery software for recovery data from that specific internal hard drive of your system.
    for more details for recovering data yourself go to - http://www.windowsdatarecovery.com
