Partitioning and File Systems Flashcards
What is Partitioning?
Partitions logically divide a storage device into multiple separate containers
What is MBR?
Master Boot Record
- Legacy partitioning scheme
- 4 Partition limitation
- After 3 primary partitions, a 4th “extended” partition is created. Then subsequent partitions are called “logical” partitions that exist within extended partition
- 2 TB max volume size
What is a GUID Partition Table?
GPT
- 128 partitions
- Drives larger than 2 TB
What makes a partition a “Primary Partition?”
It has a file system on it
What are the two layout types for Primary Partitions?
MBR and GPT
What are the two Windows File Systems?
NTFS - Supports permissions, file encryption and compression
ReFS - Next generation Windows file system
What is the main Linux File System?
ext4 - Extended file system version 4
What is the main Apple File System?
APFS - Apple File System
What is FAT32?
- Industry-wide standard
- Does not support permission, encryption or compression
What is exFAT?
- Industry standard for SDCards
- Used by Windows and macOS as an interoperability file system
What are some disadvantages of FAT32?
- It cannot store a file which is larger than 4GB
- You cannot create a FAT32 partition that is larger than 8 TB.
- It lacks the permission and other security features built into the more modern NTFS file system
What are some disadvantage of exFAT?
- Not as compatible as FAT32
- It does not offer journaling functionality and other advanced features built into the NTFS file system
What is Journaling Functionality?
(change journal)
The information about changes is recorded in a separate log (the journal) before the indexes to the files are updated. These logs are used to repair the indexes when the computer is restarted.
