I have doubts regarding this question after i received some info:
Does CTM file driver intercept disk writes by 3rd party defragmenters as well ? Does it make difference which defragmenter is used: which relies on Windows API or something else? What difference?
…Questions which first came into mind :-\
I have not enter CTM beta now ( i will soon ) but i found this on the site if it helps :
Certain boot manager and disk encryption software can be incompatible with MyDefrag (and other defragmentation programs). They assume a fixed location on disk for their configuration files, and if these files are moved then the entire disk may become inaccessible. MyDefrag contains a list of exceptions and will never move the critical files of SafeBoot, Acronis OS Selector, SecurStar DriveCrypt, Symantec GoBack, and PGP Whole Disk Encryption. Software not listed here is probably safe to use, check the manual or ask your vendor. If you know of any other software that needs a special exception then please let me know. ( from http://www.mydefrag.com/Manual-KnownProblems.html )
It does a slow but better works than Auslogics Disk Defrag my opinion ( i tested them both since they are out … ). Auslogic looks faster but wrongly show you a clean green disk and miss somes slow placements. Same for Defraggler i’ve report some MFT bugs … both crashed many times on complex disks partitions now I will check the latest versions but i am not sold
Windows System Restore is untrustable anyway just disable it.
I was beta tester for another tool i like to mention if one of you miss it : System explorer .
Along detailed informations about Tasks, Processes, Modules, Startups, IE Addons, Uninstallers, Windows, Services, Drivers, Connections and Opened Files it offers search details about file/process via online databases, system Snapshots for finding of system changes and an amazing System Report. The new stable version 2.0.1 was released today
As you can see an external defrag while CTM is installed will result in a huge increase in free space usage because CTM will protect all data in existing snapshots and will redirect the write or every single file that an external defragger attempts to “Defrag”.
EDIT: Oops, just realised that the link i supplied doesnt always take you directly to the relevant answer, so here is a quote
Can I defrag my drives after installing RollBack Rx?
Yes, you can defrag your drive after you install Rollback but you have to understand how Rollback works.
The objective of defragmenting is to optimize the hard drive for efficient use by the Windows File System and, thus, improve system performance. Defragmenting tools are Windows applications. They work by looking for fragmented files and moving them into contiguous extents.
Rollback Rx does not distinguish between applications - it just protects your entire root drive (0) - usually your C: Drive. So the Defragmentation run is seen as a massive “change in data” by an application. Therefore, it ensures that your “before change” data is protected – so Rollback ends up protecting the fragmented version of your files. This may not be an optimal result.
For detailed information of Defraggers and how they interact with RollBack Rx - please read our Whitepaper on Defragging.
Here are our current recommendations for defragging with Rollback Rx:
Clean up and Defrag your drives before installing RollBack Rx, so you start with a nice, defragged system.
RollBack Rx has a build-in snapshot defragmenter – use that to defrag your system. It’s fast and it works with RollBack Rx.
If you really need to defrag the drives with a third panry tool: Uninstall RollBack Rx, defrag the drives and then reinstall RollBack Rx.
