How To Recover Data From Invisible Hard Disk Partition On Windows 7

While working on a Windows 7 machine, there are various situations where the partition appears to be invisible. Some of the reasons for invisible partitions are mentioned below.

  • Blue screen error while working on Windows 7 often makes the partitions invisible. It has been seen that after the repair startup only the boot partition is visible.
  • You might experience the situation in case of switching from an older operating system to Windows 7. However, you might see the partitions during the boot process.
  • Partitions can also become invisible if you try to roll back your operating system from Windows 8 to Windows 7. However, you might see the drive while selecting the drive for OS and on disk management.
  • Converting the partitions based on NTFS file systems to FAT 32 file system can also lead to partition deletion.
    Note: With the evolution of NTFS file system, it is very unlikely to revert to an older file system like FAT 32. However, if required, that can be done through the inbuilt Windows utility. It requires you to format the system, which can be done through the snap-in disk management features of Windows. In any case, it stands a risk of partition and data deletion.
  • A Damaged Master Boot Record (MBR) damages the partition table. The MBR contains code to start the boot process, and it gets created along with the first partition.
  • Damaged partition table can modify the information about the primary partition and the extended partition.
  • If the first sector of the partition gets damaged, the file system would not be able to use the information to access the volume. The first sector partition is the boot sector partition.
  • Files like NTLDR, ntdetect.com, and boot.ini might get corrupt or lost. These files are the boot files and are responsible for the Windows to boot.
