Who is the largest manufacture of hard disk drives?
who is the largest manufacturer of memory is made up of hard disk drives
What was the first ever hard disk drive?
The first hard drive was made in Silicon Vally. The hard drive was made by a company, IBM.
What is the function of disk platter in Hard Disk?
Computer hard disk drives may be made of a stack of one or more disks (made out of metal or ceramic) covered in a magnetic "paint". Each of these disks is called a "platter".
What is it called when one Randomly writes magnetic ones and zeroes to a hard disk?
It is known as overwriting, in which a program is used to write zeroes and ones on the hard-drive. Several passes may be made to ensure the original data has been completely overwritten. Simply formatting a hard-drive is no good, as the data is still on the hard-drive, only the links to the data is removed, and the data can be recovered.
Is a hard disk magnetic or optical?
Magnetic storage is used on hard drives and floppy disks. Sectors of the disk are charged magnetically and are easily changed later. Optical storage uses a laser to read data. On a cd/dvd, the laser picks up tiny marks made starting in the center and rotating outward.
What are the disk in a hard drive made of?

What is a reusable information storage device made of a floppy piece of plastic inside a hard plastic protector?
floppy disk
Does a 60GB playstation3 have better graphics than a 40GB playstation3?
no. hard disk has nothing to do with grapihcs. but a 20 gb playstation has less features than a 60 gb playstation that's because the company made it like that. hard disk is just concerned with sroteage.
What is the likely drive letter for a UBS drive?
drive letter of an USB drive can be any letter from E to Z, It also can be D if you don't have DVD drive connected to the computer &C is the hard-disk drive needed for the Windows. It depends on the hard disk partition you had made.
Data is stored in the same manner on hard drives CDs and flash memeory cards?
Absolutely NO, Hard disk is made up of a ferromagnetic material such that data is stored in the hard disk by magnetization.the hard disk has a read/write head such that it magnetizes and demagnetizes the platter and also detects the amount of magnetization. but flash memories use transistors to store data in it.when a 5V current is passed in a transistor it is similar like holding a 1 bit data.thus flash memories has transistors which hold data by passing current. since transistors occupies a large space the working of thousands of transistors are simplified in to single chip known as IC.tis technology is known as VLSI.thus flash memories has a IC which stores data in arrays..
What are the disks in older hard drives made of?
Aluminum with a ferromagnetic oxide coating was what the hard disk was made of in older disk drives. This was SOP back in the day. Today, we still see aluminum, but we also see glass and a couple of other minor contributors. And we've moved away from iron-based magnetic media to cobalt-based. Need links? You got 'em.
If a cache can be made as large as the device for which it is caching for instance a cache as large as a disk why not make it that large and eliminate the device?
Though the size of a cache has increased over time, so too has the size of hard disk. An economical comparison of cache versus hard disk space in a cost per MB analsysis will show that a cache would be significantly more expensive. Furthermore, cache in general is considered "temporary" or volatile storage which means that the contents of the storage device is lost when the system is powered off. A hard disk, on the other hand, is "long term" or non-volatile storage; when the system is powered off, the hard disk still safely holds the data stored on it.
