The Sata revolution has almost eliminated all other hard drive technologies(IDE and others) and has grown considerably with the release of terabyte drives that come in the same package footprint. With manufacturers going past the terabyte range like Western Digital that has released an external drive for the Mac at 6 terabytes(actually two 3-terabyte drives combined) the limit is actually again about the technology.
Hard drive technology has developed at breakneck speed in the couple of years but competition from the solid state memory market has been biting at their heels. Today, gadgets come with solid state memory that takes up the function of the hard drive but consuming less power and without the buzzing hum we are used to with hard drives.
SATA hard disk enthusiasts will have something to look forward to next month as Toshiba announced the a new 1.8 inch hard drive.
The new hard drive will use low insertion force, or LIF, SATA connectors. What this means is that we’re now going to see hard drives that are actually ten percent smaller compared to the standard size of micro SATA 1.8 inch hard drives.
These new drives have been specifically designed for use with mobile devices like tablets, cameras, portable hard drives and media players, among others. The new line will initially be available in the following hard drive capacities – 160 GB, 200 GB and 220 GB.
Before the handy hard disks came, bulky, metal boxed like devices used to be the hard disks. In the 1950’s, hard disks were as big as cabinet files and were very complex to operate. IBM came with a new one and it was much smaller than the 1950’s hard disk however, it still could not fit a personal computer. It was attached separately to the “mammoth” computer. The hard disks that were sold by other companies (IBM’s rivals) during those times were also huge and contained large magnetic disk packs. These magnetic disk packs rotate continuously, reading files and pieces of information stored in it.
Imagine the personal computer as an “electronic” city. As the user sends commands to the computer, all the computer parts inside are working together to complete the single task the user sent.
Some of the parts’ roles are clear: the motherboard acts as the brain of the computer; the USBs are for additional ports, the LAN is for the internet and so on and so forth. However, do you know the purpose of the RAMs? The computer has two kinds of RAMs, the main and secondary. The main RAM sends the information to the secondary RAM, and the sole purpose of the secondary RAM is to store these said pieces of information. Have you ever wondered why gamers choose high RAMs? Because the speed of the game (graphics, sound etc.) is dependent on how high the RAM is.
The Central Processing Unit, or CPU for short, is the brain of the desktop computer.
The Control Unit or the CU and the Arithmetic and Logic Unit also known as the ALU are the subsystems of the core unit. When these two are combined, the CPU is created.
The CPU has many input and output devices including the 32-bit microprocessor, the Read Only Memory or the ROM and the Random Access Memory popularly known as RAM. The CPU has two slots for its memory: the Main memory and the Secondary memory. These two memory slots have different purposes and both are important to make the CPU run.
Every tangible thing can conk out anytime. Even if you take care of your things, damage can never be avoided. There are a lot of do it yourself tips on the internet for almost all the possible repairable damages your things at home might encounter.
How about computer damages? If you are a computer expert, then by all means, do the repair on your own. However, if you know nothing about computers and plan to follow a do it yourself tip to fix that computer part (hard disk for example), do not dare experiment. Aside from ruining the warranty of your computer, you might damage more parts inside just by tinkering with it.
The Universal Serial Bus (USB) in the computer is a port that allows, well, devices with USB connectors to be attached or linked to the computer. This port enables the user to attach a wide variety of hard drives to store their data.
In some operating systems, the devices you attached to your computer through the USB are detected automatically (so, less the hassle of looking for the driver and installing it manually). These devices range from USB flash drives, additional external devices such as ROMs, floppy drives (though you’ll most likely find only a number of people who still use this) and so on and so forth. You can even transfer files from your mobile phone to your computer’s local hard drive through the USB (if your computer or mobile phone is not Bluetooth or infrared capable).
The motor has an outside rotor; the stator windings are copper-colored. The spindle bearing is in the middle. To the left of center is the actuator by means of a read-write head beneath the tip of its very end and close to center; the orange stripe next to the side of the arm, a threadlike printed-circuit cable, attaches the read-write head to the core of the actuator. The elastic, to some extent ‘U’-shaped, ribbon cable just about visible below and to the left of the actuator arm is the elastic section, one last part on the hub, that continues the link from the head to the controller board on the reverse side.
The size of an HDD can be considered by reproducing the number of cylinders by the quantity of heads by the number of segments by the quantity of bytes/sector. Drives with ATA interface, bigger and in excess of eight gigabytes perform as if they were prearranged into 16383 cylinders, 16 heads, and 63 sectors, for compatibility with older operating systems. Contrasting in the 1980s, the cylinder, which calculates reported to the CPU by up to date ATA drive that has no longer definite physical parameters given that the reported numbers are controlled by historic operating-system boundary and with zone bit recording.
Hard drives can get quite cluttered and can easily get crammed with unwanted files and others and as any techie knows, a deleted file here rarely gets deleted in the real sense. A deleted file normally has the header information deleted with the space it occupies made available for storage. The file fragments are still on the hard drive till they are over-written by new data that is stored over it. Time will come when a computer system may become sluggish and the only way to return it to it’s full glory would be to do a full format and re-install of all the necessary drivers and software.
