6. Extended Partition Doesn’t hold an operating system Basic Disc Logical Drives Basically large named folders in the Extended Partition

7. Basic vs. Dynamic Disks Uses NTFS or FAT32 file systems Can create primary partitions or active partition Dynamic Disk – unknown file system (Microsoft won’t tell anyone how it works)

8. File Systems NTFS FAT16 FAT32

9. FAT16 The Primary Partition can only be up to 2 GB File names can only be 8 characters File extensions can only be 3 characters

10. FAT32 32 GB Size Hard drives (Basically) Used mostly with Windows 98, 2000 and some XP No security available
