How could I block my broken cluster on the hard disk so they can not be used anymore

Hard drives are formatted in "clusters". A "bad cluster" means that a portion of the disk is not working properly.
If your computer no longer recognizes the drive, then the drive is bad.

reformat your computer, bad block means a small clusters under clusters, try to reformat it using bootable dvd/cd of operating system..

No
innstall its driver on your computer

Hard disks DO NOT like hard knocks, this hard disk is broken, especially when they make loud noises.
It can't be fixed, by us mortals. Cheaper to get a new one.

Hi,

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.

No bulbs on an 01. Odometer is digital readout. I pulled my cluster and jiggled the plug at the top of the cluster. I had to pull out the blue keeper on the plug (and broke it) to loosen the plug. It is hard to remove. The odometer came back on but went off when I replaced the cluster. I finally got it to stay on (pushed the bottom of the cluster) but it went out a few days later. I checked the wiring from the tranny to the fuse block. It was rubbing on the steering shaft but no broken wires. Check IGN1 fuse on fuse block in left side of dash. Another tip said change the main batteries if they are swollen (mine is). Dealer said the cluster goes bad sometimes - $250 to replace. Could be a loose solder joint on bottom of cluster where the odometer is. Cluster may be hard to disassemble.

always use NTFS - NTFS is the standard file system of Windows NT, including its later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008

That is a sign of Hard Disk Failure or bad clusters due to inproper formating

Perform this tests to ascertain your Hard disk durability
1. Turn Off the computer
2. Restart it, Press F2 to go to the BIOS at the black screen when the PC comes up displaying the manufacturers name:
3. Goto the Advanced Menu or the Menu Option that displays your Drives.
4. On the drive that has the problem, select the option that performs a hard disk test.

This would take sometime and at the end, the result of the test would tell if your Hard disk is bad.

A second option is to use a reliable hard disk partition software like partition magic to reformat and repair bad clusters and damaged sectors in your harddisk

Delayed opening issue of your hard disk was not being affected by a viruses. It is a hardware problem. Your problem sound bad cluster. If you are using Windows XP try to defrag it by using deframentation system.

You can access that by the following command or procedure. Click Start> Program> Accessories> System Tools> Disk Defragmenter.

After opening the system, select the hardrive detected and click defragment.

Defragmenter are working to fix any bad cluster available just leave it while waiting until done.

If you found problem such bad cluster, and already fix it. Please let me know and rate my solution SOLVED.

Thank you.
