restoring Ntfs read only in mac os x 10.4

From the PDF manual that accompanies the FTFS-3G download:

2.2 Uninstalling NTFS-3G
NTFS-3G can be easily uninstalled using the Uninstall NTFS-3G... button in the NTFS-3G
preference pane, which should be available in System Preferences once you have installed the
package. See section 4 for a description of the other features in the preference pane.
If this should fail for some reason, an uninstall script exists at the following location:
/System/Library/Filesystems/ntfs-3g.fs/Support/uninstall-ntfs-3g.sh

Even after uninstalling ntfs-3g, I can't able to mount my ntfs formatted portable harddrive in my mac book.

That's an entirely different question. You had first asked:

After installing it, I lost my ntfs read only feature in my mac book. How can I restore the ntfs read only in macbook.

Uninstalling NTFS-3G and MacFUSE through the System Preferences panel is the answer to that question. It answers your original question by returning OS X to read only access on mounted NTFS drives.

Now to the new issue. How is the external NTFS drive connected? FireWire or USB? Does it mount as you would expect on a Windows PC?

yes, it mount as in windows pc

So you can mount the drive in Windows, but not in OS X?

So we know the external drive is fine. Something then may be wrong with your OS X installation. You may be able to fix it by reapplying the 10.4.11 Combo updater. If that doesn't do it, you should consider doing an Archive and Install from the OS X installation disks and then reinstalling all available updates.

Something is wrong then. It could be a damaged file table that is causing the updater to error out.

Boot to your OS X installation disk. Don't install OS X, but when the interface gives you the opportunity, go to the menu bar and run Disk Utility. Choose your hard drive in the left column and then press the button at the lower right to "Repair Disk". If it shows any errors, repeat the repair procedure until it comes up clean.

If there are any disk errors reported, and Disk Utility cannot repair it after three or four tries, you're going to have to use something more suited to the task. Disk Warrior is probably the best program available for that.

If Disk Utility reports no errors, then I would continue on with an Archive and Install of the OS. Make sure to use the option to preserve your settings. After the installation is complete, apply all available updates.

Since Disk Utility reports that there are no file table errors on the drive, you should reinstall the OS.

Find your OS X Tiger disks. They would be the gray disks that came with your Mac. The version of OS X will be printed on disk 1. If you purchased a retail copy of Tiger separately, then use that DVD.

Boot to the OS X Tiger installation disk. Place disk 1 in the drive and restart. Immediately hold down the C key. Continue holding it until you it's clear you have booted to the CD, or DVD.

Install OS X using the Archive and Install option. Make sure to use the option to preserve your settings. After the installation is complete, apply all available updates.

Another thought. Before reinstalling OS X, download the 10.4.11 Combo Update again. Since Disk Utility showed no errors for the hard drive, the "codec overrun" error may be being caused by a corrupt copy of the combo update file you have.
