VERR_FILE_NOT_FOUND while trying to add raw hard disk in VirtualBox

I have created a bootable usb and created a virtual box raw disk with the following command- sudo VBoxManage internalcommands createrawvmdk -filename popliveusb.vmdk -rawdisk /dev/sdd1 But when I was adding raw disk to my virtual machine's storage, I was getting VERR_ACCESS_DENIED error. Then I followed this solution. I changed the owner using this command sudo chown eh54n:eh54n popliveusb.vmdk. Then added my user to disk group using this command sudo usermod -a -G disk $USER. But now I am getting **VERR_FILE_NOT_FOUND** error. This is the full error-

Failed to open the disk image file /home/eh54n/popliveusb.vmdk.

Could not find file for the medium '/home/eh54n/popliveusb.vmdk' (VERR_FILE_NOT_FOUND).

Result Code: VBOX_E_FILE_ERROR (0x80BB0004)
Component: MediumWrap
Interface: IMedium {ad47ad09-787b-44ab-b343-a082a3f2dfb1}

When I run the VirtualBox using sudo, I don't have my VMs. How can I add the vmdk raw disk to my VM?
