what are the two main types of formatted partitions? file types and what does each do?
Fat-32: used for external devices, any user has access.
**NTFS: internal drives, very large files can be saved, files saved with per user permissions. compression supported.
what is formatting?
process of partitioning a HDD to store data. file system on system is installed.
when using a Basic disk, how many standard partitions can it hold?
- one of the 4 can become an extended partition and hold additional sub-partitions within it as a work around.
what is an extended partition?
used on a Basic disk. when all 4 partitions have been used up then one of the partitions has additional partitions housed within it and it becomes an extended partition.
how does one convert a Basic disk into a Dynamic disk and what is an advantage of doing so?
advantage: dynamic disks can have 124 partitions whereas a basic disk can just have 4.
* *disk management> right click disk> convert to dynamic disk
* *you can not convert a volume that has an OS on it as the OS will not work afterwords.
what is a RAID 0 disk?
STRIPED = RAID 0:
-2 or more disks are spanned as one volume and data is saved across them at the same time in stripes (faster saving). -no fault tolerance
what is RAID 1?
RAID 1 = Mirrored disk:
-data is saved on 2 disks at the same time each with identical copies
what is RAID 5?
RAID 5 = Striped with Parity:
- 3 disks minimum: volumes combined across multiple disks with parity for data redundancy.
- *not supported by desktop windows OS and must use hardware instead. or server OS
when talking about a partition that is full of data what is a Mount Point?
an empty folder saved on the partition that points to an unnamed (no drive letter) partition. data is then saved to this unnamed partition once the first partition is full of data.
how to move a physical disk from one computer to another?
basic disk: >disk manager > right click> uninstall disk
**Dynamic Disk: disk manager> right click> remove disk… once in a new computer use the Re scan & import foreign disks option.
what is DiskPart and why use it?
DiskPart: a command line partition and volume management utility. one uses this when using a windows OS that does NOT have a GUI like windows Server OS core. (Server Core). allows one to set up partitions and volumes on a disk or over several disks just like one would use disk management on a GUI.
what command is used in DiskPart (command prompt utility) to add fault tolerance when installing a second HDD to a system?
DiskPart> Add
this creates mirror to the existing hdd with the new disk.
