What
and How data is fragmented?
The
first thing we need to understand is how data gets fragmented. When
our hard disk is empty, the data can be placed anywhere on the hard
drive because file system is free to write the data anywhere on the
disk. Whaen data is stored on disk it is broken into pieces and each
piece is allocated a specific memory location in drive. If the memory
location is not contiguous the pieces are called fragmented.
Reasons
of Fragmentation:
- Fragmentation of data means “breaking the sequence of related data” it is occured after a few processes like edit of large size file,deletions, more read/write operations.Due to this unwanted spaces or gaps are created between the related data. This process lead to division/scattered of your data on hard drive into chunks.
- If your hard drive is almost full then there are more chances that the related files get separated into multiple fragments or pieces while they are being written to hard drive.
Defragmentation:Solution
to organize scattered data into sequential order:-
The
Data of your hard drive becomes scattered and unorganized after a
long usage due to which Mac runs slowly. Whenever you click to open
any file, used to find the files which usually takes 1-2 minutes to
open, now takes 5> min.
It
is because of more time taken by
processor to search and
fetch a particular file(supportive files) in scattered data on drive.
So,
defragmentation is the process of keeping related data into
sequential order in order to avoid spaces between related data. It is
an optimization technique inbuild in many operating system to avoid
fragmentation upto some extent. If you are running Mac,you need not
to worry about defragmenting your drive, because this operating
systems has the ability to defrag the data upto certain limits.For
example in Mac , HFS+ file system has the ability to minimize the
chance of fragmentation but only up to 20 MB file size.
In
simple words, you can say- “ Defragmentation means to keep
fragmented data together in contiguous memory location.” It
minimizes the data accessing time by the OS and helps your computer
to run more swiftly.
Ill
Effects of fragmentation:-
- It can corrupt the file system and partition tables.
- It decrease system performance by slowing down processing speed.
Defragmentation
using Third Party Tool:
Windows
users can defrag their drive using the inbuilt application in system
tools but there is no such tool in Mac to defrag the drive.The HFS+
file system of Mac OS can't defrag your large files like
audio,video/media files (larger than 20 MB). So, if you have those
files you must go for third party tool.
There
are many tools for defragmentation of Mac hard drive. I found Stellar
Drive Defrag the most suitable
one to defrag and maintain your Mac performance.
This
software scans your Mac
drives for this scattered and unorganized data and puts things back
into sequential order.
