How to Fix “The Disk is Unreadable” Error in Mac OS X
Mac OS X is a powerful and advanced operating system, which supports a number of storage media like hard disk, external hard disk, USB drive, CD, DVD and memory cards to store your valuable data. The external hard drives are generally used to take backup of your valuable data and safeguard your data. They can also be used to move data from one system to another. However, in some situations, the external hard disk may become inaccessible and you come across critical data loss situations. At this point of time, you need to perform Mac data recovery to work around the problem, if backup is not available.
Sometimes, Mac OS X operating system cannot read the external hard disk. When you attempt to extract data from an external hard disk, you may come across the below error message:
“The disk is unreadable: Do you want to initialize it now?”
After this behavior of Mac OS X operating system, when you attempt to fix the problem using Disk Utility tool, further error message may occur stating:
“Verify and Repair volume “disk1s3″
Checking Journaled HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid node structure
Invalid B-tree node size
Volume check failed.
Error: File system verify or repair failed.”
As stated in the above error messages, the problem is caused by missing or damaged data structures, hard disk profiles, and library files of your Mac OS X computer. It may occur because of node structure corruption or file system corruption.
As mentioned in the first error, your Mac OS X hard disk can not be used until it is initialized. The disk initialization is a three step process, which removes all your valuable data from hard drive.
The above problem can be caused by various reasons, such as iNode corruption, file system corruption, invalid system files, and more. It is required to replace the damaged data structures, to fix the problem and perform data recovery Mac.
If you fail to replace the damaged system files without formatting hard drive, you need to use Mac drive recovery software to retrieve lost data from hard disk. The applications enable you to systematically scan entire hard disk and extract all lost data from it. Such Mac recovery tools are extremely easy to use with simple graphical user interface.
Stellar Phoenix Macintosh Data Recovery software successfully recovers lost, deleted, missing, or inaccessible data from Mac-supported storage media. The software works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. It extracts data from all HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

The Most Common Laptop Repair Issues
When they were first introduced, laptops were often underpowered, expensive, and heavy. As technology has improved, modern laptops and notebook computers offer performance on par with today’s most powerful desktop computers and are lightweight, making them very portable. With portability and all the extra features, though, problems can occur that that can leave a laptop broken.
The most common hardware fault found in a laptop involves its power source. Many people are familiar with a scenario in which the computer fails to turn on after many attempts. At first, it may seem like the battery needs to be recharged, but even plugging the computer into an electrical outlet does not seem to help. Chances are that the laptop has a bad power adapter or a bad power jack. The power jack on a laptop is susceptible to damage because of the frequency of its use. With users carelessly plugging and unplugging the AC adapter, the jack can get damaged as the solder welds wear down, preventing the laptop from receiving external power. Once the batter runs out, the laptop will not function and cannot be recharged.
Another laptop repair issue that owners face is overheating. Overheating is caused by a faulty fan that stops working or by blocking the airflow into the computer. Laptops are cooled by small fans that turn on and off, bringing in cold air from the surrounding environment to cool off the electronics inside. If the fan malfunctions and stops bringing in air, the components in the laptop like the CPU and hard drive may overheat, causing the computer to shut down intermittently. Furthermore, laptop overheating can occur if airflow into the system is blocked. One common cause of this is resting the computer on a soft surface such as a pillow when in use. To prevent this, laptops should always rest on a flat, hard surface when turned on.
Laptop PCs are built for portability, but in the course of being taken many places, they can also suffer a lot of abuse. Bumps or falls are a major contributor to laptop failure. Impacts are notorious for causing hard drive malfunctions. Sudden jolts or impacts and disturb the delicate magnetic platters or reading head in a hard drive, rendering it unreadable. When this happens, the computer will still turn on, but may begin to make clicking noises and fail to boot to the operating system. A warning message will sometimes appear on the screen telling the owner that a hard drive failure has occurred. When this happens, the drive must be replaced.
Finally, some laptop faults are software related. Many users complain about their computers being slow or acting in strange ways. Sometimes these problems are more characteristic of a software problem rather than a hardware fault. Common causes of software issues include bad drivers, incompatible software, or viruses. It’s important to keep drivers and the operating system up to date, while also performing routine virus scans and disk defragmentation.
Understanding the underlying causes of laptop faults can help to diagnose the problem and remedy the solution quickly.

What Should I Look For in a Wireless Mouse?
Generally I am a big fan of wireless devices. I love the increased mobility that a wireless keyboard and mouse gives you as well as the way it cuts down on the clutter around your PC.
Wireless mice can be divided into 2 groups. Ones made for use with laptops or notebooks and those made for use with your PC. As most computer users know the track pads on a laptop are uncomfortable to use. The obvious solution is to use a compact mouse, which you can easily carry around with your laptop. When buying a mouse to use with your laptop, make sure that the USB wireless receiver is tiny. That way you can leave it in your laptop when you close it and pack the laptop into your bag. The problem with laptop mice is that they are small, so you tend to use them with your fingers. This causes your hand to become fatigued faster than with larger wireless PC mice. With PC mice you can rest the palm of your hand on the device causing your hand to take less strain over time.
The battery
Many first time wireless mouse buyers worry about the battery life of the mice they buy. Wireless mice aren’t really that heavy on battery power. With a good one you can expect it to last for 3 to 9 months, before you have to replace the battery. With some of the high end models there is a light that starts to flash when it is running low on power. Some of the high end options can be plugged into a stand to recharge their batteries. There are also products that come with a USB cable. If your batteries start running low you can plug it in and use it like a cabled mouse until you can replace the batteries.
Broadcast range
With the cheaper wireless keyboards and mice you will find that they have a very short broadcast range. That means you can’t move them further away from your PC than say a conventional cabled device. If you do they start dropping data and keyboard or mouse clicks and movements aren’t passed on to the computer. It’s always worth checking the range of a wireless device before you buy it.
Brand
Logitech is the biggest brand in the wireless computer accessories market. Their products aren’t always the best, but they have many different options and all of their products conform to a certain quality level. This means you can be assured that you are getting reasonably good value for the money you spend.
It should be clear at this point that buying a cheap wireless mouse isn’t worth the frustration. I recommend getting a top end mouse from a reliable brand like Logitech.
Now that you know what to look for in a wireless mouse read best wireless mouse for some reviews of the top wireless mice. You might also enjoy reading best gaming mouse.
