Apparently there have been some changes to NTFS in NT 6.2 (Windows 8, Server
2012) and though these changes aren't documented in detail yet (that I can
find) articles like this MSDN
article, and that several commercial defragmenters
have indicated their current NT 6.1 tools should not be used on Windows 8 or
So, what's the poop? What do the Authors of UltraDefrag say? Is UltraDefrag
5.0.6 safe to use on NT 6.2?
I was not able to successfully install the Win8 customer preview on a virtual
machine, so I haven't tested Win8 by now.
We will see what can be done to check Win8 for compatibility.
Any news on NT 6.2 support?
No, not yet since Win8 is not yet released.
Actually technically it is: the RTM version is out; anyone can get a full licensed version of the Sever edition of NT 6.2 via WebsiteSpark, and the desktop iteration of 6.2 in either it's free downloadable 'Release Preview', or the RTM images available through TechNet, WebsiteSpark, and DreamSpark all have the same file version NTFS file system and kernel level libraries. I can't feature a team of talented Developers like the UltraDefrag fellers should actually have to pay for a license(s) of NT 6.2...
I just noticed there are new defrag parameters in the NT 6.2 'Microsoft Drive Optimizer' when you type defrag /? the parameters listed are:
/A Perform analysis on the specified volumes.
/C Perform the operation on all volumes.
/D Perform traditional defrag (this is the default).
/E Perform the operation on all volumes except those specified.
/H Run the operation at normal priority (default is low).
/K Perform slab consolidation on the specified volumes.
/L Perform retrim on the specified volumes.
/M Run the operation on each volume in parallel in the background.
/O Perform the proper optimization for each media type.
/T Track an operation already in progress on the specified volume.
/U Print the progress of the operation on the screen.
/V Print verbose output containing the fragmentation statistics.
/X Perform free space consolidation on the specified volumes.
Parameters D, K, L, and T are new and were not part of the NT 6.1 defragmenter that appear to represent some new capabilities in the defrag API. It also warrants mention that there doesn't appear to be anything new represented here with respect to any special features to support ReFS...
Just an anecdotal update; it appears the main, or possibly only source of 'incompatibility' between commercial defragmenters and NT 6.2 has to do with boot defrag methods...
We will see how this ends, I will just have to get this Win8 crap to install as a virtual machine.
Well there was apparently some collaboration between Microsoft, VMware Inc., Raxco and Condusiv Technologies with respect to the NTFS on VFS that is now different then native NTFS... I've been looking for some published deatails and has yet have found nothing but this may obviate developing and testing defrangmenting for NTFS on bare metal.
It's 2013 now and I was wondering of it is yet Windows 8 compatible?
I was able to install a test environment, but the test machine is not working as expected without UltraDefrag.
This is the first Windows release that gives me headaches and I have installed hundreds of systems successfully in the past.
We can't test if the system itself is unstable.
I didn't see a way to send a private message but may I ask what your test machine setup is? I have been running Windows 8 on bare hardware and in a VMWare VM since RTM without any trouble. Maybe I can help
I only succeeded to setup a Win8 VM at work, but at home I fail.
The VM from work doesn't even run at home, where my hardware is much newer than at work.
Seems I need to do a clean install of my system or change hardware at home.
Thanks for your offer.
I am running Windows 8 Pro natively and UD runs perfectly. No issues at all. Everything just works.
Thank you for a great app.
Thanks for the information.
We hope to get a running Win8 system soon to be able to fully test it ourselves.
Is there any tests you would like for me to put it through and I can then post my results?
Since you don't have my test drives, I have nothing to compare with.
