🖥️ CompTIA A+ Lab 8.1.6 — Create Virtual Hard Disks

🖥️ CompTIA A+ Lab 8.1.6 — Create Virtual Hard Disks This lab demonstrates how to create and manage virtual hard disks (VHDs) for virtual machines, which are essential for storing operating systems, applications, and data within a virtualized environment. ________________________________________ 🧠 Key Concepts Virtual Hard Disk Overview: • A virtual hard disk (VHD) is a file that emulates a physical hard drive for a virtual machine (VM). • Types of VHDs: o Fixed-size: Allocates the full disk size upfront o Dynamically expanding: Grows as data is added, up to the maximum size o Differencing: Stores changes separately from a parent disk (used for snapshots) • VHDs allow portability, isolation, and easy backup of VMs. CompTIA Exam Tip: Know how to create, attach, and manage virtual disks and understand the difference between fixed vs dynamic disks. ________________________________________ ▶️ Step 1 — Open Virtualization Software • Launch your hypervisor (e.g., VirtualBox, VMware Workstation, Hyper-V). • Ensure your VM is powered off before adding or modifying disks. ________________________________________ ▶️ Step 2 — Create a New Virtual Hard Disk 1. Select the VM → Settings → Storage → Add Hard Disk 2. Choose Create new disk 3. Select disk type: VHD, VDI, or VMDK (depending on hypervisor) 4. Choose disk allocation type: o Fixed-size → preallocates the entire disk o Dynamically expanding → grows as needed 5. Specify disk size (e.g., 20 GB, 50 GB) ________________________________________ ▶️ Step 3 — Attach Virtual Hard Disk to VM • Ensure the VHD is attached to the appropriate controller (SATA, IDE, SCSI). • Verify it appears in the VM storage settings. ________________________________________ ▶️ Step 4 — Format the Virtual Hard Disk • Boot the VM with an OS installer. • Use the installer’s disk partitioning tool to initialize and format the virtual disk. • Assign partitions and file systems (e.g., NTFS for Windows, ext4 for Linux). ________________________________________ ▶️ Step 5 — Manage Virtual Hard Disks • Resize or expand dynamic disks if more storage is needed. • Clone or copy disks for testing or backup. • Snapshot or revert using differencing disks to save VM states. ________________________________________ ▶️ Step 6 — Test Disk Functionality • Ensure the OS recognizes the new disk. • Test read/write operations by creating files or installing applications. • Verify disk is stable and accessible within the VM environment. ________________________________________ ⚠️ Important Notes for CompTIA A+ Exam • Fixed-size disks have better performance but consume more host storage. • Dynamic disks save space but may slightly impact performance. • Differencing disks are useful for snapshots and testing scenarios. • Always ensure VM is powered off before modifying disks to prevent data corruption. ________________________________________ #CompTIAaPlus #VirtualHardDisk #VHD #VirtualMachines #ITVirtualization
