LAlarm is free laptop alarm security software, which sounds an alarm when a laptop is in danger of being stolen or losing data, and it destroys data if the laptop is stolen. LAlarm protects laptop and precious data against theft. It also prevents laptop failure and data loss due to HDD (hard disk drive) errors and sudden power loss. 1) Protect laptop against theft. Laptop theft is common and a constant threat to laptop security. LAlarm emits a loud siren sound when a thief tries to steal a laptop. For example, removing the AC power cord from a locked laptop will trigger the alarm. 2) Protect data against theft. LAlarm protects sensitive data in a laptop by permanently destroying the data if the laptop is stolen. The US Department of Defense clearing and sanitizing standard (DOD 5220.22-M) is used to ensure that data is securely destroyed. 3) Prevent data loss. The HDD (hard disk drive) holds important data but is subject to frequent error and logical or physical damages due to various causes. If error or damage is detected at an early stage, it could be repaired before becoming a more serious problem and prevent serious data loss. LAlarm alerts the user of both physical and logical disk problems. 4) Prevent laptop failure. Hard disk drive problem is a common cause of laptop failure. But most users are not aware of such problems being developed and escalated until the HDD finally halts and the data becomes irrecoverable. LAlarm detects signs of HDD deterioration and recommends a HDD replacement, thereby, a laptop failure is prevented. As a result, a costly laptop repair expense is saved. 5) Prevent laptop damage. LAlarm alerts when a possible sudden power loss is imminent. The user will then be able to save the data and shutdown the computer properly and/or switch to the AC power. LAlarm not only helps prevent data loss but also the hardware damage because a sudden power loss could damage the laptop hardware and corrupt data. 6) And more...
