Initialized the disk(empty/fresh) as MBR and GPT
MBR/GPT is record store on Harddisk , contains information of
paritions, partition size, location
OS and bootloader location
MBR - Master Boot Record
-4 Primary partition
-3 primary or 1 Extended
-in extended we create no of Logical partitions
-Partition size upto 2TB
GTP - GUID Partition Table
-128 Primary partition
-no extended and no logical
-Partition Size more than 2TB and max 18EB
----------------
Basic Disk
-Install OS
-Create simple partition/ simple volume
Dynamic Disk
-We convert Basic disk to Dynamic disk without loss of data
-we cant convert Dynamic disk to basic disk without loss of data
-For creating volumes -spanned, stipped, mirror and raid 5 volumes
-combining two or more disk into one volume
-we cant install OS
------------------
File System:
Define how to store data in the disk
FAT -File Allocation Table
FAT - partition size upto 4GB
FAT32- partition size upto 32GB
-cant store big files
-now days we use for SD card,flash drives,pendrives
NTFS-New Technology File System
ntfs feature:
disk quota
security
compress
encryption
indexing
-can store big size files
-partition size upto 2TB (win xp) , more than 2TB
exFAT
-more than 32GB
-can store big size file
ReFS
-Resilient File System
-Error currection with CRC
-CRC - Cyclic Redundancy Check
data may get currepted by frequent access of data
to privent from curreption store data in refs format drive
Linux/Unix: ext2,ext3,ext4,xfs
Network Sharing:
NFS
CIFS
DVD - UDF
