A Bash script that monitors the five critical SMART attributes identified by Backblaze as early warning signs of drive failure.

Based on Backblaze's data center research, the following SMART attributes are strong indicators of potential drive failure when their raw values are non-zero:

• SMART 5: Reallocated Sectors Count
• SMART 187: Reported Uncorrectable Errors
• SMART 188: Command Timeout
• SMART 197: Current Pending Sector Count
• SMART 198: Uncorrectable Sector Count

• Linux system with SATA drives
• smartmontools package installed
• Root privileges (required for accessing SMART data)

1. Install smartmontools if not already installed:

# Ubuntu/Debian
sudo apt install smartmontools

# Fedora/RHEL
sudo dnf install smartmontools

# Arch Linux
sudo pacman -S smartmontools

2. Clone or download this repository to your preferred location

Run the script as root:

sudo ./smartie.sh

The script will:

1. Check all SATA drives in the system
2. Monitor the five critical SMART attributes
3. Report any non-zero values, including drive model and serial number
4. Show a checkmark for drives with no issues
