While fixed VHD probably has the same design, it does not get bigger, so the failure situation does not occur. Dynamic VHD has a design flaw that can kill the VHD if the host PC has a disk error while the VHD size is getting increased. Dynamic starts off with a very tiny header file and gets bigger as more data gets written in. Fixed builds a full-size disk file taking up the entire final size of the disk from the very start, before any data gets written into it. Virtual disks can come in two types: fixed and dynamic.

As long as you open the Virtualbox VM with the logged-on account, which means typical methods like clicking the guest and clicking Start, double-clicking the guest, etc, not doing weird things with getting the guest to start under another account, then Virtualbox should also have write permissions to the shared folder. If you can use your logged-on account on the host PC to open Notepad and save a new file into that shared folder, close it, re-open it and edit it and save it again, then the account has write permissions to that folder. The problem that I can't seem to get my head around or solve is that VirtualBox is having a ¨Read Only/Permission¨ Issue that I can't understand as to why it does. Thats why I'm trying to use a VM on my laptop with a the VHD from a shared folder on my server, my internet goes 120mbps so it should work fine. Have tried to minimize the size of the VHD to 250GB, but it doesn't seem to work even if I've cut the size down to 250GB in the VM itself through Disk Management and then through the Media Manager on VirtualBox and even tried with CMD commands and PowerShell. The reason why I'm trying to have the VHD on a shared folder is because have 8TB storage space on my Server and only 1TB on my laptop, but my server isn't strong enough to use Virtual Machines on it as its just a storage server while my laptop can run up til 2 Virtual machines at once, but only has 1TB while the VHD is at 500GB. I would never even consider running a vm from a network share, so I have never been there.
