Windows 8 volume compatibility considerations with prior versions of Windows - Tech. Net Articles - United States (English)Summary. This article describes several design changes introduced with Windows 8 which change the supported boot configurations for users which utilize multiple operating systems on their personal computer. NTFS volumes between Windows 8 and a prior version of Windows. Background. As detailed in the Building Windows 8 blog, Windows 8 introduced much faster boot times as a result of the introduction of “Hybrid.

Boot”. With the new model, Windows 8 will log off active users, but instead of terminating the kernel session, the system is hibernated. This means that the memory state of running system processes, devices, and.

Hiberfile instead of being dismounted and shutdown. On resume, the Hiberfile is read which resumes the memory state, drivers are initialized, and the user session is prepared. By not having to perform a full boot, the time necessary. Also with Windows 8, there has been work done in the NT File System (NTFS) to reduce the I/O count of log file writes.

This method helps ensure consistency of on- disk metadata structures in the event of an unexpected unclean dismount (for example caused by a power interruption). However. a side effect of this change is that the new log format is unrecognizable with prior versions of Windows, which may result in a prior version of NTFS marking the volume as corrupt (since the contents of the log is in an unrecognized format). This will trigger.

To help prevent prior versions of Windows mounting a NTFS volume with the new log file version, we’ve added logic to the NTFS driver in Windows 8 which does the following: When an NTFS volume is cleanly dismounted (such as on a full shutdown, a reboot, or a safe remove), NTFS will “downgrade” the log file structure and version number to one that is recognized by all prior versions of Windows. This helps ensure. NTFS volume is cleanly removed from Windows 8 for use in another operating system, it can be attached without the NTFS volume being marked as corrupted.

This helps ensure that by using the new log file structure in Windows 8, your device will operate with optimal performance, and with potentially reduced power consumption. NTFS will also upgrade the log file structure and version of any internally- attached.

NOTE: Most USB Flash keys or Flash Media Cards with  a caching policy set to “Optimize for Quick Removal” will not be upgraded to the new log structure and version number and do not have the potential. These devices typically report themselves as “Removable Media” and “Hot- Pluggable”. Impact to Windows Boot Scenarios. When a system with multiple versions of Windows installed is resumed from a Hybrid Boot state, the boot process will fully restore Windows 8 and remount previously active volumes. If the user selects an alternate version, the system is rebooted (which allows for active file systems to dismount and in turn downgrade the log file structure and version to one that is.

Windows) and the system will load the desired version. In most scenarios, this will not result in a previous version of Windows mounting a NTFS volume with an unrecognized log file structure and version number. However, as part of the design of Hybrid Boot, the Windows 8 kernel is not fully shutdown unless a restart is requested, thus any mounted file systems do not have an opportunity to. Hibernated. As a result, active file systems will not be down- graded to the compatible log version 1. Hibernate. Thus, removing a physical drive containing active file systems from a Windows 8 machine. Hibernated, and connecting that drive to a prior version of Windows will result in the volume being marked as corrupted. A full chkdsk run will be required to clear the corrupted state of the volume, which will return it to a healthy.

If you anticipate that you will be physically moving storage devices with a caching policy set to “Optimize for Performance”, or storage devices attached through SATA or SAS between Windows 8 and a prior version of Windows, it.
