How to Fix Hard Drive Read Errors and Data Loss Problems

If your Windows operating system is installed on primary hard drive partition, which is formatted using NTFS file system and you reformat the same partition during setup for clean installation, the partition is automatically formatted as FAT. It copies files from boot disk and then tries to restart your system in GUI mode to proceed with the installation.

However, the installation process fails and your system becomes completely inaccessible. You can not log into your system and gain access of your hdd data. This behavior leads to significant data loss, if there is no backup in place. At this point, you need to go for hard drive recovery to get your valuable data recovered.

In a practical scenario of this problem, the installation process fails and your system stops responding. Furthermore, you come across the below error message:


To fix this behavior, if you boot your system using MS-DOS disk and then run disk repair utility, you come across further error message stating:

"The media descriptor byte is invalid.
FAT copies are not the same.
Many crosslinked files.
All directory entries were invalid."

The partition repair and hdd data recovery process fails. Corruption remains intact and it does not even allow you to resume the installation process.


Microsoft Windows always formats the primary partition using FAT file system, and then it converts to NTFS. When you select to format system or boot partition using NTFS file system, Setup inadvertently writes 16 sector NTFS boot area on newly formatted FAT file system partition after file copy process completes. The problem may also occur if the partition is either damaged or corrupted.


To sort out this behavior and recover hard drive data, go through any of the below steps:

During Setup process, remove primary NTFS partition and then re-create partition to format it as NTFS.

Install Windows operating system on FAT file system and then convert the FAT file system to NTFS.

If the above methods doesn't work, format the drive and reinstall operating system. However, this process removes all your valuable data from the HDD and requires hard drive recovery software to retrieve data. The applications are capable of easily, quickly, and safely recovering your valuable data in all data loss situations.
