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.
You can run ChkDisk utility to fix Bad sectors on the hard drive(If its fixable).
This utility actually marks the bad sectors on the Hard drive and Isolate from the being accessed thats why 33% of HDD space is unreadable.(Which is very high)
There is no option to fix this HDD, so suggest you to replace it with a new one.
Hope this helps
Let me know if you have any query on this.
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.
Use the following link to download the software, which helps u to detect as well as completly remove badsectors, but before u do tat, here is the answer for wat is bad sectors..
Hard disk drive is an integral part of every computer. It stores all your information. One of the most prevalent defects of hard drives is bad sectors on the disk surface. 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.
ths is the software
A powerful hard disk tool that can detect and repair physical bad sectors on a hard disk drive surface and regenerate hard disk.
Your hard drive is divided into bits called sectors. When these sectors start to go bad, that means that the computer cannot read or write any data on those sectors. You cannot remove bad sectors and once you start seeing bad sectors it is a sign that your hard drive is about to crash permanently so you need to replace your hard drive and make sure you back up all ofyour important data immediately.
Please note that there are some third party software used by the maintenance centers and you need to approach them to cure the bad sector of your hard disk. I would suggest you to approach them as you can take the back up of your data also if it is not having any confidential data. Even if you repair the hd using such software, the hd wont last for a long period.
bad sectors are not fixable as far as hard drives go.
you mmight find software that claims ti fix bad sectors but the claim is false as they only temporarily overwrite the sectors and unmark the bad and remark to good but the problem remains to be the sectors are bad.
The best thing to do is to replace the hard drive with a good used one or a new one.
Sorry but as a technician I know what bad sectors are and what happens when you get them.
