How to locate the 7, 8 or 9-digit part number on your PC accessory and machine type/model numbers for Monitors
This year, I am taking the time to learn how to prepare for severe weather during National Severe Weather Preparedness Week, March 2-8, 2014, sponsored by the Federal Emergency Management Agency (FEMA) and the National Oceanic Atmospheric Administration (NOAA).
Being prepared to act quickly could be a matter of survival. This is especially evident during the threat of severe weather. The deadliest and most destructive tornado of 2013, an EF-5 on May 20 in Moore, Oklahoma and caused more than $2 billion in property damage. Even though severe weather was anticipated days in advance, many in the impacted areas said they did not have a plan and were caught unprepared.
While spring tends to produce more tornadoes, they're not uncommon in fall. On Nov. 17, a late season tornado outbreak that struck seven Midwestern states became the most active tornado day of 2013 with a total of 74 tornadoes.
Being prepared to act quickly could be a matter of survival. This is especially evident during the threat of severe weather. The Moore Oklahoma ESF 5 tornado is estimated to have caused about $2 billion in property damage. In November 2013 alone, at least 70 tornadoes spanned seven Midwestern states.
Severe weather could happen at any time, anywhere. Even though the Oklahoma tornado outbreak was forecasted for days in advance, and warning lead times for the tornado outbreak averaged nearly 20 minutes, there were still many people in the impacted areas that stated they were unprepared.
Here is what we can do to prepare:
Knowing your risk, taking action and being an example by sharing your knowledge and actions with your social network are just a few steps you can take to be better prepared and save your life and others.
Know Your Risk: Hurricanes, tornadoes, storms - every state in the United States experiences severe weather. Visit weather.gov to get the latest on weather threats.
Take Action: Take the next step in severe weather preparedness by creating a family communications plan, putting an emergency kit together, keeping important papers and valuables in a safe place, and learning about Wireless Emergency Alerts. To learn more about taking action, participate in a local event on April 30 through America’s PrepareAthon.
Be an Example: Once you have taken action to prepare for severe weather, share your story with family and friends on Facebook or Twitter. Your preparedness story will inspire others to do the same.

Be it the "license required" Amateur Radio, or the "no license required" more accessible CB Radio, this is a great hobby to learn about electronics, and you certainly will soon as you will find out once you start.
Following is some info regarding CB Radio, as per the FCC itself. :)
Citizens Band (CB) Service
The Citizens Band (CB) Service is in the 26.965 – 27.405 MHz spectrum range. The most common use of CB spectrum is short-distance, two-way communications using small, portable hand-held devices that function similar to walkie-talkies.
The Citizens Band (CB) Service dates back to the 1940s when the FCC established the service for short-distance communications by individuals and businesses. Over the years, changes occurred to the service such as adding additional channels and “classes” of services, however, the general use of the service remains the same. The interest in CB radios peaked in the 1970s and up until 1983 the FCC required an individual license to operate a CB device.LicensingThe Citizens Band (CB) Service is licensed by rule. This means an individual license is not required to operate a CB device. You can operate a CB device regardless of your age and for personal or business use so long as you are not a representative of a foreign government.The FCC service rules for the Citizens Band (CB) Service are located in 47 C.F.R. Part 95.
There are 40 CB channels. Each CB channel is 10 kHz.
1) 26.965 2) 26.975
3) 26.985 4) 27.005

Operating a Citizens Band (CB) Device
You can operate a CB device in any place where the FCC regulates radio communications. A CB device must be certified by the FCC. A certified CB device has an identifying label placed on it by the manufacturer.None of the CB channels are assigned for the exclusive use of any system. You must cooperate in the selection and use of the channels in order to make the most efficient use of them and to reduce the possibility of interference. If you operate a CB device, you cannot talk with another station for more than 5 minutes continuously and then you must wait at least one minute before starting another communication.
There are several additional things to consider when using a CB device, including:

Method 3 : Using bootable Disk Warrior (Paid) USB to rebuild the node structure.
If everything fails, the only option left is to use a data recovery application which can scan and recover as much data as possible. Disk Warrior 4 is one such application which saved the day for me. You can either use a bootable DVD or create a bootable USB as shown below.
3.- Boot from your Disk Warrior bootable disc from Mac Startup Manager.
4.- Use the Rebuild option to start the recovery process.
5.- Let the process complete.
6.- Once completed you will be presented with a scan report, carefully read everything and if you are satisfied proceed with replacing of corrupt node structure catalog with the one recreated by Disk Warrior. This will result in data loss of unrecoverable files/folders, so make sure this is what you need done
7.- If you used the Replace button in the step above, Disk Warrior will go ahead and do the replacement.
Anyone single method shared above can work for you, for me Method 1 allowed me to boot into Windows and use Method 2 to backup data from HFS volume and Method 3 fixed the Apple Mac OS X boot issue.
Method 2 : Using Mac Drive Pro from BootCamp to fix and recover data.
If you are using BootCamp on your Mac to dual-boot Windows which is loading fine after disk corruption, you can use the Windows utility Mac Drive Pro to recover data from corrupted Mac volume and even fix issues with it.
3.- While the above allowed me to backup my data from Mac Volume, it still did not fixed the Mac OS X boot and finally Method 3 worked fixing the Apple boot.
"Invalid Node Structure" "The Volume Machintosh HD Could Not Be Verified Completely" is one error every Apple OS user must fear, the error is a sign of corrupt storage disk directory structure and the Mac OS X built-in Disk Utility fails to fix the problem. Most of the time a user would get stuck at the Apple Logo with the spinner, even if you are lucky to boot into the operating-system you will find missing applications and issues with your dashboard depending on which part of the directory catalog got corrupted.
Luckily, we do have quite a few tricks and tools up our sleeves to get this handled properly fixing the system making sure maximum possible data recovery. In this post, I will be sharing three possible solutions to get this issue resolved.
Method 1 : Using inbuilt fsck "file system check" utility to fix the node structure.
The most easiest method you should try first is to use the fsck command-line tool from Mac OS X recovery to check and repair the consistency of the corrupted file system.
1.- Boot into Mac Recovery by keeping Option/Alt key pressed at boot.
2.- Launch Terminal from Utilities menu inside recovery.
3.- Use df command to get your Macintosh volume id which hosts the corrupt Mac OS X file-system, use the example below to recognize your "DISK ID" like disk0s2 shown below.
4.- Unmount the Mac volume by using umount /dev/disk0s2 (change disk0s2 for your disk id) and then use fsck_hfs -r /dev/disk0s2 to get the process started.
5.- Most of the time this would find and fix all issues.
6.- Once fsck_hfs finishes, use Mac OS X Disk Utility to verify and fix any remaining issues. Unluckily for me, this still resulted in errors and I had to go for Method 2 and Method 3 shared ahead.
Because of the length of this article, each method will be in a separate post.
