On a Windows Vista-based computer,you install a third-party driver that manages on-board flash memory for ReadyDrive. After you install this third-party driver, you occasionally receive a Stop error message that resembles the following:
This problem occurs because of an issue in the third-party flash memory driver. This problem only occurs when the system experiences a low-memory condition. The Ecache.sys driver that is included in Windows Vista uses large amounts of memory during startup to cache data. Otherwise, the data would be read directly from the hard disk drive. The cached data improves Windows Vista start times.
The version of Ecache.sys that is included in this hotfix uses memory less aggressively. After you install this hotfix, low-memory conditions are less likely to occur. Therefore, the problem that is described in the "Symptoms" section is also less likely to occur.
