qzx getDiskHealth

What it does

Inspects one disk's S.M.A.R.T. health with smartctl and reports status flags without treating health warnings as command failures

Command maturity: Alpha

Available for real use and feedback while its interface and behavior can still evolve. This is the current development-checkout assessment. Every future immutable release tag preserves the exact assessment shipped by that version. Available in PyPI 0.2.2.0.9. This page documents the 0.2.2.0.9 alpha development checkout.

Behavior and built-in protections

Inspects without changing state

Direct execution for this operation

Uses a native tool when needed

Works without network access

Uses your current permissions; results can vary

Validates one disk identifier and invokes the exact resolved smartctl path without a shell or user-supplied options, with a 15-second timeout. Parse, device-open, SMART-command, and checksum failures abort; disk-health bits remain structured observations. Disk access can require elevated privileges.

This safety classification was reviewed by OpenAI GPT-5.6 Pro against implementation digest sha256:47f465256648751136fa6647d37cd65a70675a7f074f7d0811a3d7466dadc860 on 2026-08-25.

NameTypeRequiredDefaultDescription
diskstrYesNot declaredDisk identifier without path separators (for example: sda, nvme0n1, disk0, or PhysicalDrive0)
viewstrNo"health"Detail level: "health" for a summary or "full" for smartctl JSON

Input examples

qzx getDiskHealth sda

Inspect the S.M.A.R.T. health of /dev/sda

qzx getDiskHealth PhysicalDrive0 --view full

Read full S.M.A.R.T. JSON for a Windows physical drive

For the complete structured payload, add --json: qzx getDiskHealth <disk> [view] --json

Representative output example

This illustrative JSON is derived from the current implementation-backed result contract. It shows what the command can return without claiming a recorded execution; values vary with inputs, host, permissions, and optional tools.

Example command: qzx getDiskHealth sda --json

Errors and limits

The public contract requires success=false and a descriptive message on failure. This catalog does not yet declare a command-specific error taxonomy; inspect the result and do not invent error codes.

QZX is alpha software. Optional dependencies, permissions, and host capabilities can change the result.
