File Loss When A File System Becomes Case Insensitive from Case Sensitive
After installing updates of Microsoft .NET Framework 2.0, the case sensitivity of Windows file system changes from case sensitive to case insensitive. In such issues, you may receive application errors and face file loss situations. The solution to recover the lost data is File Recovery.
Consider the scenario when a user enables case sensitivity on Microsoft Windows file system to make Windows and UNIX interoperable. The user installs an update for Microsoft .NET Framework 2.0 and restarts the computer.
In this situation, the case sensitivity of the file system no longer exists. Because the file system is not case sensitive, you might encounter error messages using software dependent on case sensitivity. Furthermore, it may accidentally overwrite the system metadata files due to unexpected case sensitivity and critical file loss may occur.
Cause of the problem
This behavior of Windows file system may take place due to problem in original .NET Framework 2.0 Setup that sets the value of the following registry key to 1:
HKEY_ LOCAL_ MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\ dword:ObCaseInsensitive
The HKEY_ LOCAL_ MACHINE \SYSTEM\CurrentControlSet\Control\Session Manager\kernel\ dword:ObCaseInsensitive registry key verifies whether the file system is case sensitive or not. If the value of this registry key is 0, the file system is considered case sensitive and if it is 1 then file system is considered case insensitive.
Due to the Windows Installer information update procedure, every update makes registry changes during .NET Framework 2.0 Setup. Thus, the value of registry key is set to 1, similar to .NET Framework Setup. It can overwrite the previously configured values of registry and system files.
In such situations, your important data may become inaccessible and you may face serious file loss situations. To reclaim your lost data, you need to resolve this issue at the earliest.
Resolution
To fix this file loss problem, you need to use File Recovery Software to systematically scan entire Windows hard drive and retrieve missing, lost or deleted data from it. These software come with user-friendly graphical interface and detailed documentation that enables the affected users to achieve simplified File Recovery.
These software can recover lost files from all logical data loss situations. They support recovery of various file types and some of these also allow you to add file information, if it is not present.
Windows Data Recovery is the most reliable File Recovery Software with wide array of advanced features. It supports recovery from FAT16, FAT32, vFAT, NTFS and NTFS5 file systems based Windows partitions and volumes. It is compatible with Microsoft Windows Vista, XP, 2003 and 2000.
