We all know that NTFS file system is advancement on FAT file system. NTFS Partition Boot Sector is actually NTFS metadata structure containing all the vital information that system requires to access the partition. The NTFS boot sector has all the information of partition's geometry, initial program loader and a code that is used to locate and start the startup code of partition. Master Boot Record (MBR) uses this data to load the operating system files in a system partition. There also exists a second NTFS boot sector. In Windows XP and 2000, NTFS partitions keep a second boot sector, called backup boot sector, at the end of partition, which is helpful when primary backup copy fails.

Sometimes situation comes when both the copies, primary as well as secondary copy fails or get corrupted. This condition leads to catastrophic data loss scenarios and user gets compelled to recreate the partition from scratch or reinstall Windows in case of system partition. Last but not the least if nothing works out, you are supposed to take help of NTFS data recovery software to rescue the stored data.

Assume a situation when you ...
... observe a corrupted and inaccessible partition in Windows XP. At first you would think of it as a file system issue, so you would run CHKDSK/r command to try checking and repairing the inconsistencies of the partition. But somehow that repair fails and you receive an error message saying:

The second NTFS boot sector is un-writeable.

On appearance of this error message, the Windows partition becomes totally inaccessible.

Reason behind this error

The partition is corrupted in such a way that it is preventing from writing the NTFS boot sector reliably. Therefore, both the primary and backup copies of boot sector are corrupted. The situation becomes even more complicated if FAT12 boot sector is present at the place of NTFS boot sector (a feature of ‘FIXBOOT').

Resolution

You must reformat the corrupted partition in order to rewrite the correct boot sectors as in this error case. Since the process causes the entire data store of partition to delete, you require a backup to restore it. But it's not necessary that you have maintained a valid and latest backup with you. In absence of backup you are supposed to use NTFS data recovery tool that is specially designed for resolving such corruption issues in NITFS partitions. NTFS data recovery software is a specialized tool that is easy to install and safe to use. NTFS data recovery is suitable when the partitions have been deleted, formatted and severely corrupt or the files inside were deleted long ago and are now required to be recovered. It's simple to use not a problem even for a non-technical person.
