Now that the VMDK has been merged, change the VM’s settings and point to the merged file.īefore you boot up the VM it’s a good idea to run a defrag.ĭefragmentation of Virtual Disks and Host Disks is Importantįragmentation of dynamically growing virtual disks is a major issue on all virtualization platforms. By the way instead of -t 0 you could use -t 2 for a preallocated single disk, which is the best choice for perfomance. VMMERGED.VMDK is the new file, which will be created as a single, growable virtual disk. Where vmsplittest.vmdk is the VMDK file you have right now, which is split in 2GB files. You need to power off the VM and use a tool that ships with VMware Workstation.įrom the command prompt run the following command: "C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r vmsplittest.vmdk -t 0 vmmerged.vmdk Unfortunately merging those pieces afterwards requires downtime. Next time you create a new VM, choose ‘store virtual disk as a single file’ to avoid this issue. The screen looks like this when you create a new VM, note the default is set to ‘split”: File access in Windows, however, is much better optimized when you are dealing with one large fixed file instead of many interdependent small ones. This default setting is unfortunately not very useful from a performance perspective. This setting likely exists only because some file systems can’t handle extremely large file sizes. These steps will speed up and offer better performance, during normal operation but also during backups with your VMware backup software.įirst you would want to merge split VMDKs that VMware Workstation creates by default.

This is how to see what Disk Operations may have occured.This article describes a couple of quick steps to speed up VMware Workstation. If defrag was having problems you may want to check there was no auto repairing of files. Windows repairs physical disk errors automatically. Log files are created, deleted, written to, etcĤ. Disk Cleanup - it will run by itself is space is critically lowģ.

Lack of free space doesn't prevent the computer working till it's zero. Disk caching makes fragmentation irrelevent.Īll recommendation about free space are based on best guess on how an average person uses a computer. Windows only writes files where there is a lot of space to write preventing fragmentation. Most fragmented files are log files and will fragment 1 second after defragging. NTFS (and FAT32) are fragmentation resistant. Using another defragger will fight with Windows. Windows Defrag runs every three days and optimises program and system startup loading. It neither increases or decreases space used or free. You are assuming two things are related because they are close in time.ĭefrag does not change the amount of Disk Space. You are making a common mistake in logic. I would be grateful for any assistance that anyone can give me, in particular, why the defrag freed up (in my instance) so much free space. Up to 50% (which seems to me to be ridiculous!) I was down to just over 4% before I defragged, but I have seen posts advising that one should leave betweeen 10% and

There also seems to be a difference of opinion about how much free space one should leave on a hard disc to enable the pc to run efficiently. Reduces the amount of free space on a disk rather than increase it! The common consensus seems to be that defraging I have searched on various pc forums, and other posters have said the complete opposite to my own experience. However, I am very surprised by the amount of free space that the defrag process has freed up. I have decided to disabled Windows Defrag and will use Auslogics version in future, as it gives information regards the progress of the defrag, and seems to be far more efficient and quick. It completed in a few minutes and showed that the Windows Defrag had done most of the work but for some reason had failed to finish. I ran WDD but after 18 hours it had still not finished! I therefore decided to cancel the defrag, and after checking the capacity of my "C" drive, I found to my amazement that I now had 42.8GB of free space! I then downloaded the freeĪuslogics DiskDefrag and ran that. My "C" Drive has a capacity of 222GB and I was down to 9.68GB I am not in the habit of running Windows Disk Defragmenter very often, but over the last few weeks I have been going through the process of importing my very large cd collection on to iTunes.
