The emergency alerts system is a useful feature on most smart devices with a SIM installed. Some government agencies can access the system even when you do not have a SIM installed on the device. The system is used to push notifications (alerts) on unforeseen extreme weather conditions, natural disasters to Amber alerts (missing children). I do not promote the idea of disabling alerts, but if for whatever personal reasons you would like to disable it, you can do it on most current Android devices. The following guide is based on Samsung One UI 1.0 but it is applicable for other devices. If you do not have a Samsung device, the settings for changing the behavior of emergency alerts can be found under general system settings. Type “emergency alerts” on the settings search bar.

Recover Data from Internal Hard Drives
Computers are made of multiple different components. Not all components are vital to the operations of a computer. For example, failure of a disk drive (DVD/BlueRay) would most likely have little to no impact on other functions of a computer. But a failure of a vital component such as the processor, power supply, or malfunctioning of a hard drive will lead to a situation where the computer is no longer operational. Do not panic. You may be able to recover data from such computers using either an external enclosure or using an IDE/SATA to USB adapter.
You can recover data from most “broken” computers even if you are not tech-savvy. If you perform the recovery at home (or business) by yourself, you will save from $100 to $2000 CAD (2016 estimates) on data recovery costs. Continue reading Recover Data from Internal Hard Drives
