A Comprehensive Guide For External Hard Drives in India October 29, 2016

When talking about computer terms, you would definitely hear the word external hard drive very often. But for people who are not into the computer world, they would definitely ask what that thing is. An external hard drive is the same type of hard drive that is located inside the CPU of a computer or the laptop except that the hard drive is mounted in a separate casing and is found outside the CPU. It also functions the same as the computer does like storing information permanently or temporarily. The only difference is that it is connected to the computer via a USB or Fire wire cable and most operating systems will automatically recognize the hard drive allowing the users to use it freely to their hearts content.

But there are several types of external hard drive in India and when one is buying, they prefer to have the best external hard drive there is so the tendency is they look at the brand and the price of the hard drive without even looking at the features. Though most computers can recognize the hard drive but not every hard drive contains the same features as there will always be a difference in everything that is why the hard drives where divided into two types, the portable external hard drive and the desktop external hard drive. Regardless of the type, all the external hard drives are just having the same.

Two Types of External Hard Drive

Portable External Hard Drive
These hard drives are usually 2.5” hard drive in a slim line enclosure that is why they are easily carried thus the name portable. Though this hard drives are portable, it is also breakable and sensitive so extra care is needed when handling them. The portable external hard drive for mac is commonly USB Powered, which means you can just plug it to the USB port of the computer and you can use it. The only problem with this is that when all the ports in the computer or laptop are used then you have to remove one of the connected USB port so that you can plug the hard drive to your computer or laptop in order for you to use it.

Desktop External Hard Drive
Desktop external hard drives are normally 3.5” hard drives mounted into a larger casing than that of the portable hard drive. The device may also have fans integrated to assist in keeping it cool during use which extends the life of the disk drive. This external drives are designed mostly for the use of storing without being portable. It has a memory capacity that can reach up to 500 GB but now there are devices designed to have a 1 terabyte storage capacity. These are connected through the use of USB as well and it can be carried by other people also but the power supply should always be carried as well in order for it to be used in other computer devices.

Understanding External Hard Drives

If this drive isn’t spinning up, putting it in the freezer for about an hour will usually get the drive spinning again so you can copy needed files before the drive warms up again. A hard disk is a set of rigid magnetic disks aligned ona spindle, which is rotated by a motor. Remove the drive from the Laptop/Notebook and attach it to the IDE-cable of a Desktop computer. In our simple disk, the disk doesn’t have to do much. The first thing you want to do is run a disk utility like Norton disk doctor or wddiag (if it’s a western digital drive) to verify whether the drive is working mechanically or not.

A rotary structure moves a stack of heads relative to concentric tracks on the surface of the disks. You’ll need to find out how to remove the drive from your computer, normally with modern Notebooks/Laptops the drives are removable and it’s just a screw or two to get them out. In particular, it must just wait for the desired sector to rotate under the disk head. If it is a master boot record problem, sometimes running disk/mbr will correct the problem. The entire apparatus is contained in a tightly sealed case. Don’t forget – always power down your computer before you remove hardware. This wait happens often enough in modern drives, and is an important enough component of I/O service time, that it has a special name:rotational delay(sometimes rotation delay, though that sounds weird).

It could also be a virus, and a program like F-prot will look at the drive as a physical unit. A micro-controller takes care of steering the motors and translating the higher-level protocol that a computer uses to communicate with the disk to and from a bit stream, which is processed by specialized hardware (a DSP or FPGA) and fed to the heads. As soon as you’ve managed to remove the drive you’ll need a Notebook-to-IDE-adaptor which you can get at any computer store for under $15. Jumper your drive asa slave and connect it via this adaptor to any Windows computer.

Trouble Shooting External Hard Drives

Prior to describing the hardware in any detail, we will identify how we classify possible failures associated with a system. First, unplug the drive from your USB port and try plugging it into another USB port on your computer. If after doing this the drive does not spin up at all (you can tell by feeling for vibration on the drive), then either the drive or the power adapter has failed. Sometimes the fix is easy and sometimes it is a bit more complicated. We divide the failure types into generic failures and specific failures.
external drive troubleshooting

  • If it works in one USB port but not another, you may have a dead USB port.
  • You will need to replace the power adapter to proceed with troubleshooting.
  • In this article, I’ll try to go through the different solutions on Mac and Windows for fixing this issue.
  • Generic failures will be addressed in the next section, with the rest of this chapter focusing on specific failures.
  • If you’ve plugged the drive into a USB hub, try connecting it to the computer instead.
  • If after replacing the power adapter, the drive still doesn’t spin up, then you will need to replace the drive.

How the drive is formatted and what file system is being used is the most common reason why drive is not recognized. Generic failures will, however, be an ever present possibility any time a problem is encountered. Some USB hubs won’t provide enough power for your external drive to function. You will find links for data recovery and warranty replacement below.
There are quite a few explanations for this problem & I have compiled this guide to address almost all of the known issues & help a user get rid of these problems for a smoother computing experience. The rare exception (but growing more common) is a 7mm thick “slim” external USB HD in both Toshiba and WD in certain models where the SATA bridge has been incorporated into the HD controller board, to save time of mfg. and money in production costs. A hard disk works with any Molex connector from the PC’s power supply. If the drive does appear in the lower window (for example, as Disk 1 or Disk 2), the drive’s partition may be corrupted. Install the drivers onto your computer via the driver installation CD (it came with the Iomega hard drive). Older Windows XP computers require this installation.

Making Windows Recognize the Drive

Current production (late 2013 and on) Toshiba 2.5″ “Canvio” and most USB WD drives have incorporated the SATA card into the HD controller boards which eliminate a quick and easy fix on this issue. Make sure the plug is fully inserted. If, in the box to the right of Disk 1, 2, etc, you do not see Healthy or something similar, and if the colored stripe is black, the drive is Unallocated. Once the installation CD is inserted into the computer, follow the prompts to complete the installation process, then restart the computer. Some USB cables split into two USB connections for your Mac and lead to the single USB connection on the hard drive.

Molex connectors require a lot of pressure to fully insert, and even more pressure to remove, so don’t be afraid to push hard or pull, as the case may be. Or, the stripe may be blue or green indicating a partition is present, but there may be no assigned drive letter, which means the partition may be corrupt or may be a type not supported by Windows. Avoid connecting the hard drive to a USB hub as this occasionally prevents the computer from detecting the drive. This is known as a USB power cable. Just make sure you handle the plastic connector, and do not try to push or pull the wires.

Some reasons why a drive doesn’t show up in My Computer.

Or it may indicate a formatting labeled as RAW. Instead, make sure it is hooked up directly to the computer system. This provides more power for the hard drive, and enables it to work directly from your Mac. Next, you want to check for any pending updates under Windows Update. The most important way to save your data from inaccessibility is regular backup. You can pick one up for around £5. Some of the updates might be related to the drivers and therefore needs to be installed on the computer. Cloud storage is the latest technology to save all the digital data in logical pools. So check if you need to update your drivers. There are various cloud backup services available that provide backup solution for both Windows and Mac platforms, such as Drop box, Google Drive. Visit the related website and search for the latest drivers available for the hard disk model and install it on the computer and check if that resolves the issue.

Basal Thermometers To Measure BBT For Determining Ovalution June 17, 2016

One of the most frequently asked questions doctors get about pregnancy is “what is the best time to get me pregnant?” It is neither the Christmas time nor the Valentine’s Day. One needs to be good in mathematics if one is serious about wanting to get pregnant fast, as it totally depends on the ovulating days. Now the question arises that how should one calculate this crucial time? For people who are good in mathematics need not worry but others should get hold of an Ovulation Calculator. It is important to have some knowledge about one’s own body and its functioning in order to find out the probable dates of ovulation. Ovulation is key to the “get me pregnant” quotation. The ‘post ovulation time’ or the ‘Luteal Phase’ is the period between ovulation and the first day of the menstrual cycle.

basal thermometer UKThis period consists of fourteen days and is the same for most women. After fourteen days of the ovulation the period starts. Now what one needs to know is the date due for the next period. By counting back twelve to sixteen days from this date, one is likely to get the days of ovulation. Generally, women who have a cycle of twenty eight days, ovulate on the fourteenth day. Since this is so important to know in order to get pregnant fast, the ovulation date can also be checked through the BBT technique or the Basal Body Temperature. This is a method that involves the recording of vaginal temperature every morning by a best basal thermometer 2016 (with a fine calibration). The basal thermometer displays a higher temperature on the day of ovulation that the other days. Fertility is always highest when ovulating, so it’s important to know when you are releasing eggs.
To explain this fact in a simpler way, the egg starts developing from the end of the menstrual cycle and between the 8th to 12th days it is at its maximum. So the chance to “get me pregnant” is the most if one has intercourse on the 8th, the 10th and the 12th day. This is the most effective time to get pregnant. One shocking fact related to getting pregnant is that the egg lives only for a period of 12 to 16 hours in a cycle! Many gynecologists are of the opinion that the life span of the egg ranges from 12 to 24 hours. But the fertility experts say that it is likely to wither away within 15 to 16 hours. So it is important to hit it at the correct time!

Now its time to shift the focus from the Woman to the Man! If a couple has intercourse on regular basis, it is likely that the strength of the sperms may lack the desired force and the sperm count may also be less than it is required for the fertility level. In addition, the rate of sperm motility may also be hampered. Again, if the sexual union is not so frequent, there are chances that the sperms may become stale and old, making it lack its desired vitality. According to the opinion of the fertility experts, coitus should take place twice weekly for the best result.

It is surprising that though the female ovum dies within such a short period, the male sperm survives and moves about from 2 to 5 days within the vaginal canal. Keeping this fact in mind, it may be fruitful to have intercourse a couple of days earlier than the date of ovulation, so that the sperm gets plenty of opportunities to hit the egg. This can significantly increase your chances for pregnancy, so you don’t have to say “I want to get pregnant” anymore. You’ll already BE pregnant!

It is important here to point out that following all the above mentioned guidelines may not be enough to “get me pregnant.” For further assistance, one may turn to holistic remedies that helps find out the actual cause of a problem if there is any and then suggests a remedy that is accurate. These remedies are of a wide range that includes Chinese medications to acupuncture, from exercise to helpful herbs, from lifestyle changes to a healthy and balances diet. Unlike the age-old, conventional therapies which mostly fail, the holistic remedies almost always give the desired results, so you don’t have to say “I want to get pregnant” anymore. You will become pregnant easily, and be a mother at last, if you know what you’re doing!

Smartphones Uses And Architecture Guide January 22, 2016

Mobile phones are increasingly becoming popular and are carried by almost all adults whether rich or poor. Many people carry more than one mobile phones to accommodate their personal and official work. Smartphones are also used for entertainment and socializing with friends and family members.

Smartphones are getting more personal

There is no doubt that we live in the most advanced stage of technology. Innovation in modern technology is occurring at an incredibly fast pace and today’s high tech Smartphones may look a little outdated in a short space of time. Smart mobile devices will become smarter and more personable. Wearable devices like Google Glass with Smartphone features are scheduled to be launched during the next few years.

In 2014 – 2015 the smartphone market appeared to be reaching saturation level, with the number of mobile services in operation increasing by four per cent compared with 15 per cent during 2012-2013. The major mobile marketplace changes were driven by the rapid take up of smartphones and tablets as mobile devices were being upgraded and new tablets acquired by consumers, and by ongoing improvements in internet access.

Mobile Computing

mobile-computing-india
Mobile computing is an interaction between human and computer by which a computer is expected to be motivating during normal usage. Mobile computing as a generic term describing ability to use the technology to wirelessly connect to and use centrally located information and/or application software through the application of small, portable, and wireless computing and communication devices. Mobile computing involves software, hardware and mobile communication. Respectively, mobile software deals with the requirements of mobile applications. Also, hardware includes the components and devices which are needed for mobility. Communication issues include ad-hoc and infrastructure networks, protocols, communication properties, data encryption and concrete technologies.

Mobile computing means being able to use a computing device while changing location properties. Portability is one aspect of mobile computing. Also, it is referred as the ability to use computing capability without a pre-defined location and/or connection to a network to for engaging data and information. It provides decentralized (distributed) computations on diversified devices, systems, and networks, which are mobile, synchronized, and interconnected via mobile communication standards and protocols. Mobile device does not restrict itself to just one application, such as, voice communication.

Smartphone Vs Mobile Phone

A smartphone is a mobile phone built on a mobile operating system, with more advanced computing capability and connectivity than a feature phone. Figure 2 indicated a sample smartphone. The first smartphones was a combination of a personal digital assistant (PDA) and a mobile phone functionally. Some functions were added in later models like portable media players, low-end compact digital cameras, pocket video cameras, and GPS navigation units to form one multi-use device, high-resolution touchscreens and web browsers for displaying standard web sites and mobile-optimized pages. Also, Wi-Fi provided high-speed data access and mobile broadband.

Cell phones can typically send and receive text, picture and video messaging. Many cell phones can email, too. Smartphones, though, typically go a step further by syncing with the email server of your personal or corporate provider. The most usual mobile operating systems (OS) used by modern smartphones include Google’s Android, Apple’s iOS, Nokia’s Symbian, RIM’s BlackBerry OS, Samsung’s Bada, and Microsoft’s Windows Phone. Such operating systems are able to adjust with many different phone models. Also, typically each device can have multiple OS installed over its lifetime. Many regular cell phones are equipped with cameras, but not of the quality found on smartphones. For instance, the iPhone 4S features an 8-megapixel camera, capable of taking both still photos and video in 1080p quality. It also offers the ability to edit from the phone itself and enables users to share pictures and videos instantly. Zoom features, face detection and reduced motion blur are other features of the 4S camera.

Smartphone Components And Accessories

A system on chip architecture with three primary components. An application processor executing the end user’s application software with assistance from the middle ware and operating system (OS). A modem or base band processor with its own operating system components responding to the base band radio activities (transmission and reception of audio, video, and other data contents). A number of peripheral devices for interacting with the end user.

Power Banks

Dual-USB-10000mAh-Power-Bank[1]
Today most used cellphone accessories is power bank. As more and more people are increasingly using their smartphones for not only for making calls and sending text, the batteries which is used in most mobile phone get discharged in few hours. Power banks are the device which store electrical charge and can be used to recharge your mobile phone on the go. Power banks are essential a battery inside a plastic case. Nowadays many power banks manufacturer are manufacturing high capacity external battery charger that can charge iPhone multiple times.

If you want to choose a power bank, always buy a power bank that has high capacity. Power banks in India with 10000mah capacity is best for those who extensively use their mobile phones for surfing internet, watching videos and socializing with friends on net. Most power banks basically have the same function – to charge electronic devices such as mobile, tablet and iPads on the go. There are basically 3 types of power banks in India today. The most used power banks are ones that have USB ports and they are known as universal power bank. Solar power bank is also getting some popularity nowadays, these power banks have photo voltaic panels which can trickle-charge the internal battery when placed in sunlight. Solar power banks are mostly purchased by those individuals who want to go for camping for more than 2-3 days.

Hard Drive – An Overview January 16, 2016

The fundamentals of a hard drive are usually positive performance, before now you have used a computer be it to play games or engrave a document. Extra than do you have been familiar with how a CPU works and runs all single the programs you what hardware computer to? Well if not I will inform you. To formulate with I will build clear a modest about the times gone by regarding the computers times past. Concerning 50 years or possibly a little longer a big shot came up through the thought that all the boring stuff like arithmetic might be computerized so humans would not encompass to do hardware computer components all. Thus the CPU, as to who exactly turned it rotten. Along with this acquaintance he began to craft little programs that could explain arithmetic problems.

DIY Solar Power Components January 15, 2016

There are three types of solar panels: single crystal, poly-crystalline and amorphous silicon. Single crystal is currently the most efficient of the lot. Multi-crystalline solar power components are slightly less efficient than the single crystal. They are made from special crystals that are grown together in an ingot. Amorphous Silicon components are made by pouring a very thin layer of silicon directly onto a sheet of glass or plastic.

The main component of a solar panel, a solar cell, is created by using two thin sheets of impure silicon that are covered with a sheet of glass or plastic. The first silicon layer is called the n-type and the second silicon layer is called the p-type. When these two components come into contact they generate their own electric field. When this happens a barrier or diode is formed between the positive and negative sides. This allows electricity to flow in one direction between them.

Both sheets of silicon are covered with a conductive material to help fully harness the solar power. An anti-reflective coating is applied over the conductive material layer. Solar light hitting the solar panel creates a solar pump which drives electrons from one silicon sheet to the other. The electron flow creates a current and the cells electric field creates voltage. The two together make solar power.

If you actually want to use this power then you will also need a solar power inverter or converter component. The power produced by the solar panel is direct current and the appliances in your home operate on alternating current. So the converter is necessary to turn the energy into something usable for your house.

The solar modules should be mounted on a well constructed holding structure and placed on your roof. In the case of your solar power components generating a surplus of power the power will flow back into the main power grid through the electrical utility meter, causing it to run backwards and giving you credit on your power bill. You can buy pre-made mounts or make the components yourself out of aluminum, angle iron, steel and wood. Each has its own advantages and disadvantages. Aluminum is lightweight and strong and will resist corrosion. Stainless steel is the most expensive option and can last for decades. While wood may be the easiest to work with it may have difficulty withstanding the weather elements over long periods of time.

So now you know a little bit about solar power components and how everything works together to produce this clean, green source of electricity.
