At this point, we can try to write the bad block and see if the drive remaps the bad block. If it cannot remap the block, use badblock option -B with reiserfs utils to handle this block correctly.
An error is reported and the bad block is found to be at LBA with the following command:. To get its size in LBA block size bytes or 0. You can verify if this is the actual bad block with dd command :. If the command issues some error, then the calculation for the bad block is correct.
Otherwise, recheck the calculations to find the correct block. Once you have found the correct block, resolve the issue with dd command as explained in all above examples:. All the examples given in this article concentrate on finding the correct bad block and the partition.
Once you have found the bad block, all you need to do is to run dd command to write zeroes on the block. The different examples provide the methods of finding the bad block location in different filesystems and in different scenarios. Thanks for the page I'm having problems trying to find the partition offset with fdisk on my gpt partitioned disks. For disks that have been partitioned with gpt, I have to use gdisk right?
The script below finds bad sectors, puts them into a text file, then test if text file size is different than zero, so e2fsck will mark bad sectors these sectors will not be used by operating system.
It looks like dd command must have bs parameter equal to physical block size, not logical one. Thank you for that detailed information! It is very valuable for me. Can you recommend me a simmilar tool for that case? Would steps be simmilar for a ntfs filesystem?
Booting from USB and following your instructions I managed to clean it, then wrote a new basic hosts file and got things running again. Already have an account? Sign in.
