partitioning
process of electronically subdividing the physical hard drives into groups of cylinders called partitions

C:
D:
format the drive
installs a file system onto the drive that organizes each partition
basic disks
creates MBR and partition table and stores them on the boot sector
boot sector
the first sector of the hard drive
MBR
tiny bit of code that takes control of the boot process from the system BIOS

look in the partition table for a valid OS
primary partitions
designed to support bootable operating systems
up to 4
lettersC: - Z:
extended partitions
not bootable

do not get letters

only get 1
logical drives
after creating a extended you must create this

gets a letter D: - Z:
C:
always reserved for the first primary partition in a window pc
active partition
on or off
at boot the MBR chooses which partition to load and boots that OS
volume boot sector
stores information important to its partition

location of OS boot files

every partition on a hard drive has one
dual boot
multi boot
able to run more than one OS on a machine
no fixed disk present
forgot to tell CMOS to look for the hard drive

reboot, access CMOS and try setting the drive up again
basic volumes
primary partitions and logical drives on basic disks
dynamic storage partitioning
dynamic disks

spanned volume

make as many volumes as you want
spanned volume
goes across more than one drive

risky - if one fails you lose all data
hidden partition
primary partition that is hidden from your operating system

hide backup copies of OS incase you mess up
swap partition
linux and BSD systems

act like RAM when your system needs it
root directory
provides the foundation upon which the OS builds files and folders
FAT file allocation table
card catalog that keeps track of which sectors store the various parts of a file

data structure

two column spreadsheet
FAT16
16 bits
usb thumb drives
high level formatting
OS located bad sectors, mark them as unusable, prevents files from being written on them
clustering
enables you to format partitions larger than 32 MB
end of file marker
FFFF last cluster
bad sector
FFF7
fragmentation
files in FAT start to separate
disk defragmenter
rearrange the files into neat contiguous chunks
FAT32
supports partitions up to 2 terabytes

32 bits to describe each cluster

dont need defragmentation as often
New Technology File System NTFS
redundancy
security
compression
encryption
disk quotas
cluster sizing
master file table MFT
NTFS

a backup copy of the most cruicial parts of the MFT in the middle of the disk

reduces the chance that a serious error can wipe out both the MFT and the copy
NFTS Security
access control list

only one person can access a direct path of folders

C:\programs\davids secrete folder
NFTS Compression
save space by compressing

access is slower since you have to uncompress
NFTS Encryption
right click my computer
properties
advanced
click encrypt contents to secure data


**windows xp home and media center do not support EFS
NFTS Disk Quotas
set quota on users hard drives

stops user from monopolizing hard drive

must log in as admin

right click hard drive/properties/quota tab/make changes
NFTS Cluster sizes
you can adjust the cluster sizes unlike FAT16 and FAT32

supports partitions up to 16TB by default
disk management
control panel
computer management applet

start/run/diskmgmt.msc
foreign drive
disk management

move a dynamic disk into another computer
formatting

(disk management)
see this when formatting a drive
failed
disk is damaged or corrupt
lost data
online
healthy and communicating properly
offline
the disk is either corrupted or having communication problems
importing foreign drives
right clicking the disk icon and selecting import foreign disks
converting to dynamic disk
right click and convert to dynamic
very safe and quick

reversing it is not
dynamic disks supported by
not supported by windows xp and windows vista home editions
simple volumes
dynamic disk

acts like primary partition
spanning volumes
dynamic disk

if you run out of space, attach a new hard drive and span the volume - dont have to make new letters
striped volumes
dynamic disk

spreads out blocks of each file across multiple disks

faster
dangerous - lose one drive lose all data
Mount points
place in the directory structure of an existing volume that you can point to a volume or partition

mount a folder on the drive (therefore you add a hard drive to the C drive)
CHKDSK
check for bad data
repair

my computer/right click on the drive you want to check/properties/tools tab/check now button

run once a week
disk cleanup
start/all programs/accessories/system tools/disk cleanup

monthly
