Partitioning Your Hard Drive In Windows 2000/XP

To start partitioning in Windows 2000/Xp environment, right click My Computer and select Manage, once you enter into the Manage screen, from here select Disk Management.

This main screen will show you the existing drives with the new ones. At this instance Windows usually open up a wizard to help partition and format your new drive. If it does not, right click the new drive in the lower pane and select initialize drive.

Now you can partition your drive by following these steps.

1. Right click on the new drive and select new partition, then it will launch the partition wizard.
2. In this step it will then prompt you how much drive space you want to allocate to the new partition.
3. If you choose not to use the full amount of space for the first partition, you can create additional partitions in the same way up to a maximum of four partitions per disk.
4. Now it will ask for a drive letter which Windows will use to represent partition as C: or D: etc.
5. Once you’ve created the partitions, you’ll have to format the newly created partitions which Windows will prompt to do automatically.
6. Once formatting is complete, reboot your computer, and you’re done.

Western Digital Inflates 3.5in HDD Storage To 6TB Using Helium

Storage is always getting cheaper and more capacious—but Western Digital has a plan to fill it with helium to make hard drives way more efficient than ever before.

If you could see inside a normal hard drive, you’d find it was a pretty brutal environment. The plates on which data are stored spin at incredibly high speed—thousands of revolutions per minute—and while you might not expect it, it’s the drag from those plates spinning through the air inside the drive that limits the number that can be stacked together. Yup, just like air resistance stops vehicles going fast, it does the same to your data.

But instead of air, Western Digital is now creating hard drives that are filled with helium, reports All Things D. Lighter than air, helium cuts the drag forces right down, allowing the manufacturer to squeeze more plates inside. Indeed, it can now squeeze in five where previously it could only manage seven; the first drive to roll off the production line has a capacity of six terabytes, versus four for conventional drives, for instance.All Things D explains what that means:

Deploying 11 petabytes of storage using current drive technology requires 12 racks and 2,880 hard drives, and about 33 kilowatts of power to run them. With the new helium-based technology, you could do it with eight racks and 1,920 individual drives, and run them on 14 kilowatts.

Perhaps predictably, the first units won’t be for consumers, but rather commercial enterprises. So, Netflix will be using them to store movies, and CERN to store experimental data. Then maybe, one day soon, you might have some helium in your hard drive, too. [All Things D]

Type of Hard Disk

1. Parallel Advanced Technology Attachment (PATA)
These types of drives are also known as Integrated Drive Electronics (IDE) and Enhanced Integrated Drive Electronics (EIDE) drives. The labels relate to the type of interface that is employed to connect the disk drive to the CPU board. These drives utilize either a 40 or a 80 wire cable with a broad 40-pin connector. 40 wire cables are utilized in older and slower hard disks, whereas 80 wire cables are used in faster ones. Nowadays, these types of hard disks are being substituted by SATA hard disks. EIDE hard drives were introduced after some advancements in IDE hard disks, however, the term IDE refers to both IDE and EIDE disk drives.

2. Serial ATA (SATA)
These hard disks use a totally different connector than their PATA counterparts. Moreover, they also employ a different power adapter than IDE ones, though adapters are easily attainable. The main difference between a SATA and a PATA hard disk is that the former is thinner and purportedly have a faster data interface than the latter. Nevertheless, this speed dissimilarity is not distinguishable in PATA and SATA drives which have the same rpm rating. SATA drives are more efficient, and use less power than PATA ones.

3. Solid State Drives (SSD)
These hard disks, unlike the other types, don't consist of moving components. Typical hard drives comprise of a spinning magnetic disk that performs the function of data storage, but SSDs use semiconductors for this purpose. Since there are no moving components, these hard disks are much faster and less likely to break down than other drives. However, their price is a bit more than other hard disks.

	PATA	SATA
Data burst Rate	Up to 133MB/s	Up to 150MB/s (SATA I)  Up to 300MB/s (SATA II)
Sustained Throughput	52MB/s	55MB/s
Cable pins	40	7
Power connect pins	4	15
Cable length	18"	40" (1 meter)
Hot pluggable	No	Yes
Power consumption	5V	250mV
Jumper settings	Yes (Drive 0 or Drive 1)	No

These are some hard drive types that are generally incorporated in desktop computers and laptops. I hope this article would have helped you with different types of hard drives.

Introduction to Computer and information system

INTRODUCTION

This course is designed to cover fundamentals of information systems. The course will cover basic hardware concepts, the structure or architecture of computers, and the software hierarchy from system software to application programs. Student are also introduced to the concept of database and information system development

In this assignment / mini project, students have to demonstrate their understanding on current technology on today’s society and demonstrate using website (blog); particularly on the use of HTML and CSS.

for this assignment, i would like to create Zoom IT blog spot. this blog is about going to tell you about type type of hard disk, Parallel Advance Technology Attachment (PATA), Serial ATA (SATA) and Solid State Drive (SSD).

We also want give some info about how to make a partition in Windows XP/2000

and lastly we will tell about latest technology from Western Digital (WD), the new hard drives filled with helium
