A recent Microsoft update (deployed as
KB 2732673,
KB 2775511, or
KB 2824408) may result in data corruption when using ArcGIS on a Windows 7 system and writing data to remote data storage on a Windows Vista, 7, 2008/2008 R2, or 2012 system. This data corruption appears as truncation of a write request and has shown up in file geodatabases and shapefiles.
Microsoft has acknowledged the problem, identified the affected component as RDBSS.sys, and provided further
details.
How Microsoft Made These Updates AvailableKB 2732673 and KB 2824408 are hotfixes to address specific issues. The KB 2775511 update is a cumulative update that is available exclusively at
http://catalog.update.microsoft.com. Because it is available only through the Windows update catalog, the KB 2775511 update is not considered a security update by Microsoft and is not being deployed broadly.
