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.

How To Fix Bad Sectors on the Hard Drive


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 many times a harddisk can be formatted?


hi,

in a long course of use it is quite natural to format the harddisk...

(due to viruses or something like that)

when formatting,
the operating system needs a file system to organise data into files and folders....
so they can be managed effectively...
when formatting it clears a particular area called a partition then divides it into sectors, tracks formed by the combination of these sectors, and cylinders...

sector is the smallest data block in hard disk an operating system can manage...

if not frequent formatting a hard disk not at all a problem....

you need not worry about the hard disk or its performace....

if this one help please give a vote....

Lags and says has bad sector after 14 months


Good day sir/maam, hi, 14 months is too short for a hard disk operating span, what we do is run the diskmanager software that comes with the seagate hard disk, on the diskmanager menu, run the low level format which usually removes the bad sectored space out of the way, and mark it as not usable. then may I suggest you partition your hard drive to 2, one for windows and the the other for data. call your computer dealer if they have in house techs for service, or get the copy of disk manager for your seagate. Hope this helps, thanks
