Maybe it is caused by bad sector

    A few days ago, a message saying "windows detected a hard disk problem"
    appears when I log into Vista.
    Initially, nothing happen. Suddenly one day, my Vista started lagging(very
    serious).
    I therefore make it to be a USB external HD, and then try to copy the files.
    However, the HD stops working when reaching certain sector while copying. I
    attempt to repair it by using chkdsk tool and Seagate repair tool, the
    process stopped at a percentage.

    Any solution for me to copy my files please?

    Thanks for any idea.

    The most reliable way I've found:

    Have another drive with room for an image of the bad partition.
    Boot a Linux Live CD.
    In a terminal window: 'dd if=locationofbaddisk of=locationtoputimage
    conv=noerror conv=sync'
    The noerror tells the copy to keep going past bad blocks while the sync
    tells it to replace bad blocks with zeroes.

    At this point you will have an image of the partition in a file on your
    disk. You can now loop mount, fsck and read all the files on the image.
    I've done this several times on bad disks and successfully retrieved the
    data on the drive.

    It works!!!! you help me a lot!!!! Thanks a lot!!!

    How about those folders, e.g. My documents? It said "Access is denied." I
    think it is the matter of privilege. How can I overcome it?

    Your OS needs to mark that as unusuable sector, obviously. I t can STILl
    work fine, but now hear this:

    If you're working with critical files, e.g. for government or in my case
    reaearch - if one sector went bad, more may follow.
    It's an emergency for people like me, but maybe not for your home/basic
    users.

    I'd immediately save all documents and replace driver EVEN if a single
    sector went bad, I'd use it as a scrap, backup for noncritical data, etc -
    but never hold OS or important stuff on it again, ever.
    Bad sectors might be due to software, but usually it's a real bad physical
    failure meaning magentic film covering your plate - one or more magnetic
    domains are unable to change & hold its B-field phase.

    In plain English something started to 'go off" on your platter. Many years
    ago however I kept using a harddisk with a BUNCH (not just one) bad sectors,
    because ot was a home laptop and in those years a portable (laptop) harddisk
    cost so much, you'd have a heart attack. $400 or so, now apply infaltion
    factor and it's like $600 today, since then I only use IBM-marketed,
    Hitachi-made drives. I love Hitachi for thei rpatents & reliability, if you
    buy many USB external drives today, chances are inside is a Hitachi,
    regardless of what labelign says on outside.

    My "black list" includes Western Digital - high failure rate, don't like
    them. I usually prefer Japanese or American military-grade for all small
    electronics, e.g. IBM/Hitachi (IBM used to own that division), Seagate, etc.
    For external driver I used to prefer Iomega's but not sure what HDD supplier
    they used and it faded away, Iomega is now mixed with dozens of others, used
    to be elite.

    SimpleTech external USB drives use Hitachi.

    There're companies whose entire busienss is data recovery from physically
    damaged media (harddisks or optical).

    Their service costs plenty and only makes sense for corporate or government
    customers.
    But if you can afford, and who know s- it might be cheap in your case, maybe
    you can inquire....

    They take your drive apart and analyze with secret methods, reading signals
    too weak for consumer-grade storage devices, and they use software
    algorithms. this is how they recover from what seems to be irreversably
    damaged drive. Obviously FBI can probably read your bad sectors, question
    is the $cost.

    You need to take ownership then give yourself permission to at least read
    the files. Google or Bing for take ownership.
