As in the computer field for several years, I have a lot of people who are afraid to save data to your computer to be seen. People are so paranoid, but do not really know what to do if they are willing to spend a little time to learn about the box with cup holders into (CD-ROM tray) = 0) was built.
Every time I build a computer or install Windows on a computer person, I always partition the hard disk into C: and D:. Partitioning is a process in which the installation is a hard drive and see for yourself, your computer has two hard drives. C drive will always be a primary partition and D and all other drive letters, always a logical partition is his. He can use FDISK in Windows 98 boot up disk (XP has a program to install on the CD and it will ask if you create a partition) to create two partitions on a hard drive you want. It is good practice, because if there is something wrong with Windows, all data stored on the D drive in tact, because Windows is installed on the C drive, remember (“Your computer thinks it has two hard drives as one).
Another good practice is to buy an external hard drive, Zip, or a tape drive depending on how large your data is, to have extra backup just in case, which is rare but does happen, the partition gets corrupted and the Logical drive is no longer there. I always tell my clients to save data that is critical to be on an external drive and to turn it off or at least take the connection out from the computer after every backup session, so that in case there’s a total system crash, or a hacker getting into the system, the data is not there to be damaged or tampered with.
