Cache Manager Causes File Loss on Windows NT Based Computers

You can come through corruption and the file system of the situations of loss of files if you are using NT version of Microsoft Windows operating system on a FAT (file allocation table) partition / volume or CDFS (file system compact disk) volume controller that has a file system filter operation. In this case, you can lose your critical data, application or media files and facing grave situations of data loss. To address these issues, it is necessary to opt for the powerful and advanced data recovery software.

It is possible that this problem due to MDL (Memory Descriptor List) interactions between the system filter drivers, the SMB (Server Message Block) server, the Cache Manager and FAT. There is a bug in the cache manager of the NT-based versions of Microsoft Windows that could result in corruption of the file system and the loss if the conditions mentioned below are true:
Windows NT based operating system or file server (Srv.sys) is running and the exchange of data on the local system from FAT (Fastfat.sys).

Note: This problem does not occur if the file server is sharing data on the NTFS file system-based computer. However, the issue could occur with other file systems or that the exercise codes MDL (Memory Descriptor List) I / O (input / output) in a manner similar to Srv.sys.

The system uses the Windows operating system filter drivers. The file system filter driver must be aware of CDM Fast routines and this should filter the E / S file system FAT.

For example, when the filter of the filter unit input / output in the SMB server that is split in the FAT system. The requests for E / S, which are derived from the network via the server system to filter into the drive and FAT partition, can result in file corruption.

Resolution

You can sort this behavior of Microsoft Windows operating system by installing the latest version of the Windows NT kernel (which includes the Cache Manager). No longer ignores the performance of the filter unit, which indicates that the filter does not write data and free the MDL.

You can avoid this problem occurring in the future, but will not solve the ongoing problem of corruption and lost files. To solve this problem, you need to use File Recovery Software.

File Recovery Software is advanced and powerful third party tools that scan the bottom hard drive and extract all data from it. These are equipped with interactive software and simple graphical user interface and allow you to achieve fast and safe do-it-yourself 'File Recovery.
