I created an 8GB RAM disk using the default dynamic allocation method. I needed more drive space and attempted to increase the size to 10GB. The RAM Disk Configuration utility accepted the parameter and dismounted the existing RAM disk but when it attempted to mount the new drive, nothing happened. After half an hour I rebooted and the 8GB drive is what I still have. I tried this twice with the same effect.

I'm following the same process I have used in the past with IMDisk. Is this broken, or do I need to do something else to increase the RAM disk size?

I'm using the April 20, 2026 release.

Cannot reproduce the issue.
Please try to disable your antivirus, reinstall the software, and do again what you did previously.
