A Python utility to scan for bad blocks and create safe partitions on a storage device. This tool automates low-level disk preparation, ensuring partitions are free from damaged sectors, making them suitable for subsequent Btrfs filesystem creation.

Features

• Detects the device's hardware sector size.
• Scans for bad blocks using badblocks.
• Creates multiple partitions that avoid bad blocks.
• Prepares the disk for a manual Btrfs filesystem creation.

⚠️ Warning:

• This tool is not meant for production use.
• Running this script will delete all data on the target disk. Use only on non-critical drives and make backups first.

Prerequisites

Ensure the following tools are available on your system:

• badblocks
• parted

These tools are typically pre-installed on most Linux distributions. If not, they can be installed via your package manager.

Usage

⚠️ Warning: Running this tool will erase all data on your disk.

Prerequisite before running: The target disk must have a GPT partition table and contain no existing partitions.

1. Clone the repository:

   git clone https://github.com/stony-letter-strategy-aptitude/btrfs-with-badblocks.git
   cd btrfs-with-badblocks

2. Run the script:

   python src/main.py

   The script will:

   • Detect the device's hardware sector size.
   • Scan for bad blocks and save them to badblocks.txt.
   • Create partitions that avoid the bad blocks.

3. Manually create a Btrfs filesystem:

   After partitioning, you can create a Btrfs filesystem on the new partitions:

   sudo mkfs.btrfs -L my_btrfs /dev/sdX1 /dev/sdX2 /dev/sdX3

   Replace /dev/sdX1, /dev/sdX2, and /dev/sdX3 with your actual partition names.
