Fsck will do a standard filesystem check in Linux. Read the fsck manual pages (man fsck - from terminal) for usage instructions. Additionally, most drive manufacturers make a diagnostic boot disk you can download to check the drive for further errors than fsck can.

If you are still having problems after using the drive manufacturer's tools. and assuming your drive passes those tests, you can always try a low-level format with DBAN or a similar tool to completely erase the entire drive (this will completely erase every part of the drive, even the partition map and master boot record thereby requiring a reinstall of all software). From there, you can decide if your drive needs further repair / replacement.

Hope this helps!

Tip

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.

Cant fix error


this sounds like a HDD problem, your best is to download a live operating system such as knoppix and boot to it, once in check that you can see the HDD it will be shown as "sda1" gather all data and information you want to keep and reinstall your OS

if you are using windows and you havnt made a recovery disk, then you can either contact the manufacturer to send one out or buy the windows install disk

I have a Acer Aspire3680-2022 Laptop and can't boot it up. I checked the Bios and it seems to be Ok.


It could be. It could be your boot sector is placed on a bad sector of your harddrive that's why your going in repair page everytime you boot, because it cannot read your boot sector properly. Removing your harddrive and check it with HD Tune Pro to find if there is a bad sector on your harddrive. HD Tune Pro can be used in Trial Mode, google for it.

I have an 500GB toshiba external hardrive,it still has 50G more space left..however when i tried to open it again..it wont open...it 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.

Dell lid was slammed bad sectors and slow processing...


Honestly even if you were to get lucky and be able to get vista back onto the laptop, your going to get even more bad sectors quickly cause the hard drive is going bad.

Get a new hard drive put in there and then get the laptop restored back to factory defaults.
