Hello,

my uncle has bought new harddisc of size 80 GB. His friend told him that it would be better to split it on two parts with fdisc.
I would like to know why would it be better? What are the advantages of this? And if it has a sense how to do it exactly in fdisk.
thanks

Hi xLeon,

this is just a personal opinion. Splitting is normally done because of splitting data from the OS/programs. In case you have to re-install the computer, you still have all data backed up on the second partition.

This is all I'm going to say about this, as it's really a personal opinion.

Greetings,

LucF

This means that we have two new units e.g. C and D? and OS is on C and our programs are on D? What means "re-install the computer"? Did you mean re-install windows? Can you tell me more accurately about this? I must confess, I don't understand it completely.
Could you write me how to split it in fdisk?

no, I meant:

You can create two partitions:
C: for the operating system and the programs
D: for all the data (document's you write, things you download, whatever)

So if you would have to install WINDOWS (sorry about this confusion) again, you will still have all of your data on the D: drive.

Just to explain a little more... (sorry about the multiple posts)

In case you have to install windows again. You will also have to install all of your programs again. Most of the time programs will refuse to run after installing windows again (because of registry entries) but you will still have access to all documents you've ever created.

Splitting Your 80GB Hard Drive into 2 partitions
is very desirable because it makes it run faster.

Imagine: which is faster? Seeking for a piece
of data from 80GB, of Seeking for a piece of data
from 40GB?  After you partitioned your drive into
2 40GB drives, your OS knows exactly where your
data is, so it doesn't have to spend time to search
the entire 80GB, only have to search 40GB.

As for how to use Fdisk, I think the program is
pretty self-explainatory, but anyway, here is a
simple tutorial if you need help:

Not true.... that's what's the index is for.

It would be very useless, if people were splitting harddisc only because if they would possibly sometimes re-installed windows to prevent data loss. Why to install windows again?
The answer from kokojie would persuade me, if you could prove it. Some link about this topic would be sufficient.

Partitioning a modern single hard drive does NOT offer a speed advantage(sales bull), it does offer easier reinstalltion of operating system independently of programs and data as LucF stated. There was some advantage in older drives because spin up and seek times were so poor that the use of multiple partitions gave improved performance.(for some of the reasoning provided by kokojie). This is no longer true or the improvement is so small that partitioning is no longer worth the effort with modern mutli-platten high speed drives.
At the same time, partitioning does not impair performance and it can make it easier to perform maintenance functions as alluded to in kokjie's referred articles.
Maintenance is the only reason that really justifies multiple partitions on a single OS, single drive system...

You accepted a comment as an answer that just isn't an answer. It's as tmj883 said, just some marketing thingy nowadays to say such things.

>>partitioning creates a lower level master index to your hard drive's contents
The index is nowadays much different from what it was in the early days, this is just a pile of b*** s***

>>scandisk and defragmentation are much quicker processes.
Per partition yes, per drive not...

>>because these checks can be done in parallel.
Sure, they can be done parallel, but they'll make the scan even slower as the hd head has to go all over the drive to check all parts of the disk instead of just following the tracks.

Sorry LucF,

your answer was quite correct and I didn't realize that the advantage is that we can format only one unit with OS and programs and the other part serves as a storage of data (movies, mp3s etc.). Now I understand it. About indices and speed of seeking I know very little.
Your answer was true from the major part and i've mistaken with the accepting of the answer. I hope I won't act rushly again.
