subject: Sis Partition Loss In Microsoft Windows 2003 [print this page] In Microsoft Windows computers, SIS (Single-Instance Storage) is an ability of your system to store a copy of the content, which multiple computers or users share. This is a method of eliminating the data duplication and increase efficiency. In some situations, you might come across SIS partition loss situations after the SIS links, which were backed up on your computer that is running Microsoft Windows 2003 are restored on the another Windows system. This behavior of Microsoft Windows requires Partition Recovery to be sorted out.
In a practical scenario, consider the following things:
You enable the SIS (Single Instance Storage) for a hard drive volume on your computer, which is running on Microsoft Windows Server 2003.
The SIS links are created for a few files in common store located on the hard drive volume.
You decrease the size of a number of files in common store from less than 1 KB to more than 32 KB.
You create back up of the SIS links and then restore these links to SIS-enabled hard drive volume on another computer.
In such situations, the restored SIS links do not point to anything. Thus you come across partition loss problems and need Windows Partition Recovery to be resolved.
Root of the problem
This problem takes place because of SIS restore module (called Sisbkup.dld). The module changes the SIS link, which point to the file that has size less than 1 KB to normal file in initial phases of SIS restore on the computer. Later on, the restore API (Application Programing Interface) attempts to resolve the problem by adding reparse point to the file.
Resolution
In order to sort out this problem and perform Partition Recovery, you need to install a hotfix provided by Microsoft. The hotfix can be downloaded from Microsoft's website. This process will not recover lost Windows partitions.
To recover hard drive partitions, Partition Recovery Software are required. They are powerful and efficient third-party applications that are capable of thoroughly scanning the affected hard drive and retrieving all of the lost partitions. The applications are built-with rich graphical user interface and thus do not demand sound technical skills to perform recovery. With read-only and non-destructive conduct, you can be sure that they will never alter your original data on hard drive.
Stellar Phoenix Windows Data Recovery is the most effective and robust application for assured and perfect recovery. It supports recovery from FAT32, VFAT, NTFS and NTFS5 file system partitions. The software is compatible with Microsoft Windows 7 RC1, Vista, 2003, XP and 2000.
