- Which storage commands are mostly for inspection, and which ones deserve much more care?
- Why is the CLI useful for storage even when a GUI exists?

What you should learn
- Inspect storage devices and mount points from the command line, and understand which commands are observational versus potentially destructive.

Concept to practice path
Each lesson is meant to move from an idea, to an example, to a safe practice step.

CLI storage rule: inspect before change
- Confirm which disk, volume, or mount point you are looking at.
- Use inspection commands first and read the output carefully.
- Separate observational commands from commands that can modify layout or data.
- Only then decide whether you need a safe practice action, a real change, or a stop-and-think moment.
Why This Matters
The CLI is often the clearest place to inspect storage on remote systems or servers without a desktop environment.
But storage commands vary widely in risk. Some merely show information. Others can destroy data or alter the filesystem state.
1. Start With Inspection Commands
Get-Disk Get-Volume
lsblk df -h mount
These commands help you answer:
- what devices are present
- what filesystems are mounted
- where they are mounted
- how full they are
2. Treat Change-Making Commands Differently
Some commands go beyond inspection.
Examples include:
- partition editors
- formatting commands
- filesystem repair tools
- commands that alter mount configuration
Storage Caution Rule
If the command can repartition, format, or repair a filesystem, do not run it until you know exactly which device you are targeting and why.
3. Why the CLI Still Matters
The CLI is useful because it gives precise names and states that GUIs may hide or simplify.
That precision matters when:
- you are on a server
- you are documenting storage state
- you need an exact mounted filesystem or device name
What to Ignore for Now
- advanced SMART diagnostics
- complex partition-table editing
- destructive repair workflows
The goal here is to build inspection discipline first.
Before You Move On
You are ready for the storage lab when you can:
- inspect storage from the CLI
- distinguish safe observation from risky modification
- explain why exact device targeting matters
Next, we use a safer external-drive style scenario to practice the storage workflow.
Learning loop
Recall it, check it, then practice it.
Do this before moving on. It turns reading into memory and safer action.
- Use one inspection command on your platform to identify storage devices or mounted filesystems.
- Explain why commands like format, fsck, or diskpart should not be run casually.
Review again after 1, 3, 7 days.
