C:\maquinas\myVM> grep HardDisk.uuid *.vbox
File myVM.vbox:
        <HardDisk uuid="{fdfb1a86-166d-4136-ac93-729a05b0d410}" location="myVM.vdi" format="VDI" type="Normal"/>
        <HardDisk uuid="{abfc2359-d897-46a0-96fd-3e25e3bf1080}" location="myVM_2_swap.vdi" format="VDI" type="Normal"/>
        <HardDisk uuid="{17544fb3-6834-41f8-a34b-604f5515ccf1}" location="myVM_3_psec.vdi" format="VDI" type="Normal"/>
        <HardDisk uuid="{cc6d693c-771d-4f8c-a49b-c5ea773cd327}" location="myVM4_home4.vdi" format="VDI" type="Normal"/>

This corresponds to 4 SATA disks under a single SATA controller:

<StorageController name="SATA" type="AHCI" PortCount="4" useHostIOCache="false" Bootable="true" IDE0MasterEmulationPort="0" IDE0SlaveEmulationPort="1" IDE1MasterEmulationPort="2" IDE1SlaveEmulationPort="3">

Therefore:

• myhost:/etc # ls -d /sys/block/sd* yields /sys/block/sda /sys/block/sdb /sys/block/sdc /sys/block/sdd
• or:
• myhost:/etc # lsblk -dn -o NAME,SIZE,MODEL

sda    15G VBOX HARDDISK
sdb 131.4M VBOX HARDDISK
sdc  59.9G VBOX HARDDISK
sdd   1.9G VBOX HARDDISK
sr0  1024M VBOX CD-ROM

I added disk sdd, at Windows it appears as myVM4_home4.vdi;

1. cfdisk /dev/sdd -- I have created a single partition (of 1.9 Gb)
2. Now sdd1 device is ready to go, after appropriate file-system configuration, as follows next.
3. mkfs.ext4 -L HOME04 /dev/sdd1
4. echo "/dev/sdd1 /opt/home04 ext4 defaults 0 0" >> /etc/fstab -- or use vi; careful, do not overwrite fstab.
5. mount -a -- to mount all partitions.
