Attach a hard drive to an existing machine

[ajdm]

Regards;
I have created a vm with Windows 10 and I need to attach a vmdk (made in vmware) to it to access the information that is in it; but in doing so I get the following error:

Could not get the storage format of the medium 'C:\Users\admin\Desktop\SRAW\SRAW-flat.vmdk' (VERR_NOT_SUPPORTED).
Result Code: VBOX_E_IPRT_ERROR (0x80BB0005)
Componente: MediumWrap
Interfaz: IMedium {4afe423b-43e0-e9d0-82e8-ceb307940dda}
Receptor: IVirtualBox {9570b9d5-f1a1-448a-10c5-e12f5285adad}
Receptor RC: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)

Does someone know how to solve the problem or know of any application that allows me to extract the contents of the vmdk?

I also had use the VBoxManage clonehd command to convert the vmdk to VDI, but I get this error:

VBoxManage.exe: error: Could not get the storage format of the medium 'C:\Users\admin\Desktop\SRAW\SRAW-flat.vmdk' (VERR_NOT_SUPPORTED)
VBoxManage.exe: error: Details: code VBOX_E_IPRT_ERROR (0x80bb0005), component MediumWrap, interface IMedium, callee IUnknown
VBoxManage.exe: error: Context: "OpenMedium(Bstr(pszFilenameOrUuid).raw(), enmDevType, enmAccessMode, fForceNewUuidOnOpen, pMedium.asOutParam())" at line 179 of file VBoxManageDisk.cpp

I will really appreciate any support to resolve this issue

Thanks in advance.
