SMART and Badblocks Testing Script

This script performs diagnostic tests on a specified block device using smartctl and badblocks. It enables SMART, checks device health, runs various SMART tests, and conducts a non-destructive write test.

Prerequisites

Ensure the following dependencies are installed on your system:

• smartctl (part of the smartmontools package)
• badblocks

Usage

./smartdrivecheck.sh <device>

• <device>: The block device to test (e.g., /dev/sda).

Example

./smartdrivecheck.sh /dev/sda

Script Workflow

1. Dependency Check

   • Verifies that smartctl and badblocks are installed and executable.

2. Device Validation

   • Ensures the specified device is a valid block device.

3. Enable SMART

   • Enables SMART on the device if it is not already enabled.

4. SMART Data Checks

   • Runs a series of checks on existing SMART data, including health status, error logs, and self-test logs.

5. Polling Time Extraction

   • Extracts polling times for various SMART self-tests (short, extended, and conveyance).

6. Self-Tests

   • Depending on available polling times, performs conveyance, short, or extended tests, waiting for their completion.

7. Non-Destructive Write Test

   • Uses badblocks to perform a non-destructive write test on the device.

8. Final Extended Test

   • If applicable, performs a final extended SMART test.

Environment Variables

During execution, the script extracts the following variables based on device capabilities:

• CONVEYANCE_SLEEP: Estimated time (in minutes) for the conveyance test.
• SHORT_SLEEP: Estimated time (in minutes) for the short test.
• EXTENDED_SLEEP: Estimated time (in minutes) for the extended test.

Notes

• Non-Destructive Testing: The script ensures that the write test is non-destructive, preserving existing data on the device.
• SMART Compatibility: This script assumes the device supports SMART. Ensure your device is compatible before running the script.

Error Handling

• The script terminates if any critical error occurs during execution.
• Specific error messages will be printed to stderr.
