Save & Optimise Virtual Disk Storage for FREE.
Save & Optimise Virtual Disk Storage for FREE. This article demonstrates a FREE way of saving/optimising Virtual Disk storage space using software which is freely available. Include is :1. How to report which disks are over-allocated using our very own free vdisk waste finder application from here > Vdisk Waste Finder (6918 downloads) 2. How to resize over-allocated vdisks using a free open source application called “gparted” 3. How to align the vdisk including system disks to a 64k start sector. This increases performance and reduces disk latency using a free open source application called “gparted”So to get started first of all download all the software by clicking on the application names above./Disclaimer: Virtualizeplanet will not be liable if anything was to go wrong whilst performing the following operations.

New update and “how to” video found >HERE<Follow these steps: parted will create a new primary partition from sector 63 to sector 127. That means the very next sector available is 128. Job Done.
