Snapshots fail to write HD device info to .vbox

Description
When taking a snapshot, AttachedDevice is not being written for the harddrive! The snapshot is rendered useless. I found that adding the XML lines with the properly referenced HardDisk uuid string restored access to the VM. See below.
Failed to open a session for the virtual machine virtualserver.
piix3ide#0: The target VM is missing a primary master device. Please make sure the source and target VMs have compatible storage configurations [ver=20 pass=final] (VERR_SSM_LOAD_CONFIG_MISMATCH).
Result Code: E_FAIL (0x80004005)

Missing the device! Added this in myself.

I guess this is a duplicate of #11750.

I had same problem in 4.2.18. Upgraded to 4.3.6 and still had same problem. The above fix fixed it for me.

Replying to frank:
We need some test case to reproduce as this normally doesn't happen. Does this also happen with a fresh (dummy) VM with only a hard disk attached? Your DVD drive ('A:') looks suspicious.
Decided A: made a perfect available optical drive letter, since obviously 5.25" drives are gone and done. Choosing A: has no ill side effects nor conflicts with any machine communication. Never have to remap the dvd drive when other drives are added/inserted.
