Microsoft is offering support to testers of Windows 7 when it comes down to issues associated with the integration of NTFS external drives with the operating system. In this context, a refresh is now available on Windows Update (WU), designed to smooth out the experience of using a NTFS external drive coupled with Microsoft's next iteration of the Windows client. The Redmond company failed to reveal the specific problems that the update was designed to resolve, but it did indicate that, following implementation, the refresh would deliver a superior experience when it came down to using external NTFS drive in Windows 7 Pre-Beta.
“An update to improve the reliability and operation of an external NTFS drive. After you install this update, you may have to restart your computer. This update is provided and licensed to you under the Windows 7 Pre-Release License Terms,” KB958456.
