The system is a direct-allocated filesystem using bitmap tracking and a single global directory.

Ø is a null pointer. Uncolored inodes have all their pointers set to Ø.

Update order:

• Data Block
• Inode
• Inode Bitmap
• Data Bitmap
• Directory

• Is it in an inconsistent state?
• If so, where were it in the file creation process when the power was interrupted?
• If applicable, how much information can we recover?

System 2

System 3

System 4

Blocks are zero-indexed (careful with orange/purple block!)
