Partitioning hard drive Slide 3: A hard drive contains a number of disks called 'platters'. These platters are coated with a magnetic substance. The platters spin at high speed under an mechanical arm (the 'actuator' arm) that moves backwards and forwards over the surface of each platter. On the end of this metallic arm is a small copper wire. The computer sends a pulse through this wire which changes the state of the magnetic surface of a platter as it passes underneath. In this way the files that you store on your computer are encoded into the magnetic substance. Jumper Settings Configuration: : Jumper Settings Configuration: Master
Cable Select Set as Master: : Set as Master: Use this setting if you are installing an additional hard disk drive to a single UDMA cable with a hard disk drive Set as Slave, jumper one hard disk drive to Set as Master, and the other to Set as Slave.
Use this setting if you are installing an additional hard disk drive to a single UDMA cable and the Cable Select setting is not recognized Ultra Direct Memory Access - UDMA Slide 6: If this is the only HDD in your computer, set the pin setting to Master HDD – Hard Disk Drive Set as Slave: : Use this setting if you are installing an additional hard disk drive to a single UDMA cable with a hard disk drive Set as Master, jumper one hard disk drive to Set as Master, and the other to Set as Slave.
Use this setting if you are installing an additional hard disk drive to a single UDMA cable and the Cable Select setting is not recognized
If this is the second HDD in your computer, set the pin setting to Slave Set as Slave: Cable Select: : Cable Select: This setting is the default setting for PATA/IDE hard disk drives. With the Cable Select jumper setting, the BIOS determines whether a hard disk drive is Set as Master or Set as Slave by it’s position on the UDMA cable. Parallel Advanced Technology Attachment Partitioning : Partitioning Separation of the OS files from user files.
Having an area for operating system virtual memory swapping/paging.
Keeping frequently used programs and data near each other Purposes Slide 10: Having cache and log files separate from other files
Use of multi-booting setups
Raising overall computer system’s performance on
"Short Stroking" aims to minimize performance-eating head repositioning delays. (deals on track of HDD) Partition Types : Partition Types Primary
Extended Primary – is a partition contains one file system
Extended – is a primary partition which contains secondary partition Glossary : Glossary UDMA – Ultra Direct Memory Access
PATA – Parallel Advanced Technology Attachment
IDE – Integrated Device Electronics
BIOS – Basic Input Output System
OS – Operating System
HDD – Hard Disk Drive Slide 13: Virtual Memory – is a computer system technique which gives an application program the impression that it has contiguous working memory (an address space), while in fact it may be physically fragmented and may even overflow on to disk storage.
Multi-booting – is the act of installing multiple operating system on a computer, and being able to choose which one to boot when switching on the computer power
