Show Notes
Most of us only think about file systems when a drive fails or a "file not found" error appears, but these systems are the invisible plumbing of our digital lives. This episode dives into the mechanics of how data is organized at the block level, comparing the universal simplicity of FAT32 with the robust journaling of EXT4. We also explore the cutting edge of storage, explaining how modern volume managers like BTRFS and ZFS use Copy-on-Write technology and self-healing checksums to protect against bit-rot and system crashes.
