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.

Fixing bad sector

Try Hard disk regenerator 2011, boot from cd / dvd and start recovery. It's a good bad sector recovery software. If you have physical bad sectors then it will not possible to recover. If it is logical then this tool can help you. search google for the software, make bootable cd or dvd and start under dos.

My hard drive is not readerable

Hi there,

If you have access to another system, download SeaTools for DOS from the Seagate website:

This program makes a bootable DOS disk that will check ALL sectors on your drive. If needed, it will give you the option to fix, including boot sectors.

Also, if you can, download the most current Chipset drivers for your system, these include the EIDE and SATA controllers, just in case.

Hope these ideas work

Hard disk

if you are installing a dos based system thn dos formatting is very good

if you are going to use xp then make boot option in setup as bootable from cd rom
put a win xp setup cd in the cdrom drive
it will boot up saying press any key to continue , and follow the scren instructions
the whole process is that simple a hd can be formatted till bad sectors are not shown up upto 8 %. more thna 8& bad sectors cannot load windows, however dos can still be loaded and so also win me so it doesnot affect the hd
what affects is the jerks and voltage supply variations on the har d disk and some bad virus infections and the temperature the hd has ... always leep hd at a tem p lower than 37 degres c
use a fan to achieve this a 12 volt small fan mounted on the hd .

Bad sector

I was looking on http:// freeware and noticed a download that claims to be able to recover data from almost anything.
Virus?? Have you checked?
HDD's tend to go bad as you are describing, "bad sectors" ever increasing, even after format more turn up. Not good. New disk required?
