Redmond's own Microsoft Corp. has this week issued a fix for a rather nasty issue that plagued the shiny new Windows 7 operating system. The problem tacked would corrupt the data a user transferred to a NTFS-formatted SD memory card via Advanced Direct Memory Access (ADMA).

According to Microsoft, the Secure Digital Bus Driver (Sdbus.sys) driver, which converts the DMA data structure of the OS to the ADMA data structure of the SD card, may set an incorrect data length in the SD descriptor table. When this happens, the data copied is corrupted and further problems could occur trying to access it.

Users of Windows 7 Starter, Home Basic, Home Premium, Enterprise, Professional or Ultimate can get the fix for the bug from this page (both 32bit and 64bit versions are available).
