The manufacturers claim 4 to 5 hours of battery life, but this cannot be accepted as true face value. Ensuring the battery can be done by regular de-fragmentation as it enables arranging data properly and faster functioning so that less load is exerted, thereby ascertaining longer battery life. Similarly, keeping external devices such as PC cards, external mouse and speakers, iPod or Bluetooth unplugged is advised as these USB devices exert more load on the battery power and thereby reduce its life.

  • Removable Disk Protection This tips is really come in handy for those who often use removable disk hardware as file storage. Moreover,  if our removable disk hardware is used on several different computers, for example from one personal computer to other personal computer or from an internet cafe to other internet cafe, then, our removable disk will be infected by viruses before we realize and resulted in data loss

    The followings are some tips to protect our removable disk:

    1.   Make 2 or more partitions

    If you have removable disk with more than 1Gb capacity, you should make multiple partition. This is to anticipate fatal damage either because of other virus or other causes, we are still able to save data one of the partitions if you have to format the disk as the last option. In making partition, use NTFS format ( support windows 2000/2003/XP) not FAT32.

    Create one safe parts ( we must enter password to be able to access the part of removable disk which is safe – secure), and another part which is able to be accessed by public. If you use Windows XP Pro ( non Home edition) and its format is NTFS you can make password at a folder with the following steps:
    Control panel >> Folder Options >> View >> See checkbox at the bottom >> uncheck it >> OK. Then, right click the folder which will beprotected >> Properties >> Security >> chek all the deny columns >> OK. The folder will turn into 0 byte.

    2.  Use applications to protect removable disk.

    There are many tools to protect the folder and also file in storage device like:
    • File Protector
    • Folder Guard
    • Folder Lock
    • Mysecretfolder
    • Usbdiskguard
    • Carryit
    • Easy file Pro
    • Etc

    From all tools above basically has the same function which is protecting folder or file with password so that others cannot access the folder or cannot be infected by viruses.


    3.  Data Compression and Encryption

    Usually every removable disk always is packaged with its CD driver, in CD driver there exist a tool for “ Compression Support” and also “ Encryption Support”. But if we didn't get tool intended by we can apply other tool like WinRar to do compression and gives password at the data compression.

  • What is SATA Hard drive?
    Every computer stores the information saved in its memory on its hard drive. A hard drive is a set of disks held up on a central spindle, and each disk is made up of many tiny magnetic bits. An antenna, called a read-write head, encodes information onto these disks by using an electromagnetic flux to change the magnetic polarity of the bits that make up the disk. The more disks a hard drive has, and the more bits on each disk, the more memory space is available in the hdd. Different computers are specialized for different uses, so there are also different kinds of hard drives that are compatible with different kinds of computers. The three types of hard drives that you are most likely to encounter are SATA hard drives, PATA hard drives, and SCSI hard drives.
    SATA hard drives, otherwise known as Serial ATA drives, are the cheapest variety of hard drive on the market. They are the newer variety of Parallel ATA hard drives, or PATA drives, which used to be the most common type of hard drive. Within the past two years, the SATA drive has almost completely taken the PATA drive's place as the most common hdd. The SATA hdd was designed for high bandwidth applications, such as multiplayer video games and video editing, so it is much faster and performs more efficiently than the traditional PATA drive. Also, SATA hard drives are easier and less costly to manufacture than PATA drives, so SATA hard drives are much cheaper in stores. The cable used to plug in the SATA variety of hard drive is more advanced than that of the PATA hard drive. The plug the cable uses to connect to the motherboard is smaller and cheaper, and it is easier to plug in without damaging the connector pins on the motherboard. Some of the newer models of the SATA hard drive do not work with the older cable ports on a computer's motherboard, so you may have to buy a SATA adaptor cable.
    SCSI hard drives are of an even older design than the PATA hard drives, but they are still used today because they function much faster. They cannot hold as much information, and they are far more expensive than their SATA counterparts, but if you spend a lot of time on fast-paced network servers, or use other high speed, high bandwidth applications, you may want to consider using a SCSI hard drive.
    The most important thing to remember when you are buying a hard drive is to get one that is designed for the motherboard your computer uses. If your motherboard and your hard drive are designed to work with each other, they will be more efficient than if you use an adaptor cable.
