📘 Filesystem vs Storage Area (Disk or Partition)

Short summary

Tutorial explaining filesystems as organizational structures written on raw disk storage in Linux. Filesystems provide metadata structures (superblocks, inodes, allocation tables) enabling applications to store and retrieve files. Low-level tools like mkfs and fdisk write directly to disk sectors and can permanently destroy data if misused.

• •Filesystems are organizational structures written on raw storage to enable file management
• •Partitions are raw storage; mounting attaches them to directories for file access
• •Low-level tools (mkfs, fdisk) bypass filesystems and can permanently destroy data
