I have an 500GB toshiba external hardrive,it still has 50G more space left..however when i tried to open it wont only shows the properties and said that windows cannot correct the bad...

There is no way to fix a bad sector. A bad sector is like a scratch on a cd that can't be fixed. You should run a program like "HD Tune", when you use a program what it does is it will read the disk and when it can't read a certain spot it marks it as a bad sector. After that the hard drive will move the data from the bad sector to a spare area of the hard drive. The spare area will store the data from a bad sector and will be usable like the old one. However if you get too many bad sectors you will run out of spares. When that happens your drive will crash.

You Can Try These Steps: Windows comes with a built-in hard disk utility software that scans your hard disk for errors and attempts to fix them.
  1. On My Computer, select the disk drive that you want to diagnose and repair.
  2. Right click on it and select Properties
  3. Go to Tools tab.
  4. Click on the "Check Now" button under "Error Checking Status".
  5. Depending up on your choice, choose either "Automatically fix file system errors" or "Scan for and Attempt Recovery of Bad Sectors."
  6. Then click on Start.

I have tested several programs, but the program below, just really worked for...

Let's try to explain the question that grinds us all when in cams about the hard disk. Can we actually repair a bad block? Before of the answer you must find some information about what is a hard disk, how does it work, what are bad blocks. After that you must identify them because you will need the exact location of the affected sectors. After you have done that you must run a few steps:
- before you try to resolve the problem with the bad sector you must extract the data that was written to that block. To do this you must run a Recovery program that you can find freeware on the net.
- bad sectors are unreadable parts on your hard disk but the nature of them must not be always physically and that part of the platens to be destroyed. The bad sectors can be simulated by some programs. This means that some programs installed on your computer can interrupt the reading process on to another segment of the platens. That is in the most happier cases but the chances that the bad sectors are cause by this is less then 10 percent. In this case is difficult to resolve the problem because even the Scandisk or other identification programs used to discover bad blocks will give a rapport that nothing is wrong with your hard disk. The best way is to uninstall the latest programs applied to the computer.
- lets supposed that you have a 20 gigabits partition on your hard disk that has bad blocks. After the identification program it will indicate you where are the blocks situated on the partition. So this way you can isolate them in to another partition that you must never use again. Another scenario can be created and the bad sectors can be at the beginning of the partition in the middle of it and at the end of the partition. Know it's a little bit tricky because you can't just go on and create three new partitions to eliminate the bad sectors from use. In this case most of the new hard disk has a spare space available just for this type of scenarios. You must access the CASH memory of the hard disk and indicates to the hard disk that instead of writing down on the effected blocks it must write to the spare blocks.
- another to restore the hard disk is to use the low level format option. Many of you think that low level format is a program. Wrong, the low level format option is set for any BIOS and can be easily use if you know some command line programming. The low level format can take to be complete a very long period of time but in the most cases we can obtain marvelous results. Actually the low level option takes every cluster of the hard disk and identifies them again (throw a thermal process) and writes down on the memory of the hard disk what sectors can be written and witch blocks are un-writable. This procedure is the best that can be because it will need no effort from your side to try and avoid the bad blocks that already exists and the hard disk itself know where the bad blocks are.
In conclusion the bad blocks can't be fixed. The problem is a permanent one and we can only try to use the hard disk until it is broken down for good. But if you are having financial problem this is a best way to keep going with your old hard disk.

How to use the disk error checking utility...

As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.If you use your computer daily, you should run this utility once a week to help prevent data loss.

  1. Close all open files.
  2. Click Start, and then click My Computer.
  3. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
  4. In the Properties dialog box, click the Tools tab.
  5. Click the Check Now button.
  6. In the Check Disk dialog box (called Error-checking in Windows 7), select the Scan for and attempt recovery of bad sectors check box, and then click Start.
  • If bad sectors are found, choose to fix them.
  • Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

    During a hard disk test, it stopped and said to replace hard disk 1

    Which tools are you using? Does it give any other information such as bad sector on hard disk? You can also check the log to see whether some details are there. If bad sector, you may need to replace the disk or fix the sector by flagging it. But it is safer to replace it because it might be the reader so it will keep breaking the surface of the hard disk.

    My computer HDD have bad sactors please help to remove this on

    When a hard disk has bad sectors, these sectors can be fixed by running check disk. This is a temporary fix as the hard disk is nearly worn out and it will get more bad sectors and evenually the hard disk will fail completely.
    Bad sectors occur when the magnetic oxide on the disk platters is worn out and data cannot be written or read from these sectors.
    To run check disk click Start - My Computer - right click on C Drive and click on Properties - click on Tools tab - then Check Now in Error Checking
    I suggest once this has been done, you back up your data and purchase a new hard disk ready to install Windows etc. when the hard disk fails completely. You may want to install a new hard drive before the old hard drive fails completely.

    How can I fix bad sectors in my hard drive

    You cannot. The disk-drive has some "spare" sectors, and it should automatically reassign them, i.e., like using a spare tire on your car when one of the 4 tires goes flat, you just "swap-in" the "spare".

    Unfortunately, unlike fixing a flat tire, there is no way to "repair" a bad sector on a disk.

    Having "bad" sectors is a sign that your disk-drive is _SOON_ to _COMPLETELY_ fail. So, it's time for you to buy a new disk-drive, and copy all your files from your "old" disk to your "new" disk. Compare it to buying insurance for your automobile, in case of a "crash" while using your automobile (or your computer).

    I have bad sectors in my hard disk what should can i do?

    There is nothing you can do about bad sectors. The Hard Drive itself, with its associated electronics, automatically maps these bad sectors and doesn't use them any more. So, the answer to your question is "NOTHING". Bad sectors may eventually make your Hard Drive unusable, and if your bad sector count is growing quickly it's time to do a complete backup and replace the drive.

Bad sectors are a part of the disk surface which contains not readable, but frequently necessary information. As a result of bad sectors you may have difficulties to read and copy data from your disk, your operating system becomes unstable and finally your computer may unable to boot altogether.

    When a hard drive is damaged with bad sectors, the disk not only becomes unfit for use, but also you risk losing information stored on it. The HDD Regenerator can repair damaged hard disks without affecting or changing existing data. As a result, previously unreadable and inaccessible information is restored.

    A powerful hard disk tool that can detect and repair physical bad sectors on a hard disk drive surface and regenerate hard disk.
