You do it by creating partitions on your hard drives. Partitions are typically created before the hard drive is formatted. Another option is to use a program like Partition Magic to edit partitions on your hard drive. You generally don't want to play around with your partitions too much after you ha…ve your OS up and running. Any error may cause you to have to reinstall everything. ( Full Answer )
Answer . 1. Hard disk space is relatively cheap, as low as 13p per GB 2. Hard disks store data without the need for a constant electricity supply 3. Hard disks allow data to be stored in one place which is more convenient than using DVDs for example. 4 Hard drives have a read/write spee…d in comparison to optical media (cds) although very low in comparison to RAM .

Since your question only requests the disadvantages, they are as follows: Consumes alot of power, the resistance of shocks is low, data error rates are frequent, weight ratios are large, the size is large, can be hard to recover data from, (SCSI) controller cards may be required, loud mechanical noi…se can be generated, heat can be generated, there are moving parts inside, the disk sectors will eventually stop working, and they can be broken if dropped (usually whilst operating). The speed of the Hard drive speed (MBS) can regulate the data transfer rate of the computer. If the jumper settings are not precise the hard drive may become fried. If you have a hard drive which is older you may find it hard to find the hardware drivers for it. Also if you have a hard drive which is older it may cause data to be corrupted on your computer and you may lose your data because of faulty transfer to/from the disk platters. ( Full Answer )
The computer's hard disk stores data - be that the operating system, application programs, documents or virtual memory. Stores data that needs to be kept between times when the computer is turned off.
\n . \nA hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile; they retain the data even when they do not have power. . The data, which can be either just informational data, or executable programs…, is written onto a spinning disk by making magnetic pulses very near the surface of the disk which make magnetized spots on the disk. The data is comprised of places which either are, or are not magnetized, yielding ones or zeros. The coils which make the magnetic field are on movable structures which "fly" above the disk, in that they are spring loaded to force them toward the spinning disk, but since actual contact would destroy both the coil and the disk, the structure is shaped like an airfoil (airplane wing), so that the relative wind from the spinning disk forces the coil structure just a small distance away from the disk. .

It is invented by the IBM team led by Rey Johnson on September 13, 1956 .
Several reasons the most common one would be to get more memory. Especially on some of the older computers that only come with 5 or less gigs of memory. I know I definatley need alot more than 5 gigs because that's not even enough to hold all of my music. Among others your hard drive may have broke …and you don't want to buy an entire new computer when you can get a new decently large hard drive for less than 100 dollars. ( Full Answer )
A hard disk drive is used to store data. That data includes theprograms you use. When someone says they are installing somethingon their computer, they usually mean they are installing it totheir hard drive, which is located inside their computer. In mostsituations, a hard drive is what loads the op…erating system so youcan use your PC. If it fails, you will not be able to fully bootyour PC. ( Full Answer )
hard disk drives (HDD) store all the data, operating systems (windows,mac etc) and all the files. HDD is the most important drive and there cannot be a PC without it.
IDE HARD DISK. SCSI HARD DISK. SATA HARD DISK. EXTERNAL HARDDISK.. IT IS ALSO DIFFER BY RPM SPEED FOR THE HADD.
\nA hard drive is where all your data is stored, personal and system data. It is kept even when the PC is powered off unlike RAM. It is one of the most vital parts of your PC. Without it you could not store any files or install any application software let alone run it. Due to the sensative nature o…f a hard drive it is enclosed in a metal case to prevent damage within your system unit. One single particle of dust can crash the hard drive and cause massive data loss. And force you to replace it and reload all of your data. Also it is recommended that you defragment your hard drive as preventative maintence. Also it is recommended not to move your PC while its running because this can cause your hard drive to crash. In order to explain how I would have to talk about the complete architecture of your drive. \n. \nComputerguy1984 ( Full Answer )
I presume you are asking if you can use an external drive on different computers? The simple answer is yes but you can't install programs on the external drive to run on other computers (except the one it was installed on), this is because programs spread themselves in different parts of the compute…r, so bits of the programs would be missing if you tried to run it on another computer. Other than this the only problem is viruses which can be transmitted through infected files if you aren't careful where you plug in. NOTE the external drive "could /will" change its drive letter depending how many drives are on the host computer this isn't a problem! just be ready to look for your files in a different labelled drive in "My Computer" (presuming you are using a windows computer) ( Full Answer )
all you have to do is you have to smash it with the hammer or put it in microwave
You have been infected by a virus. Update your antivirus and scan it. On the other hand use the tool below, it will no doubt fix your problem.
Well you look at the ROM and then you look at the megabites to see how many there are and compare it to the RAM.
The hard disk is the brain of the computer. It has the operating system installed in it to run the computer, and the data you provide goes into storage in the hard disk. With time, they become larger in capacity. What ARE the uses of a hard disk in the computer? To magnetically hold programs and… data files on a smaller and easier to get to system. WIthout a hard disk - you would have to run your system using only yhe CD's that it came with - and the CD's that all programs came with!!! ( Full Answer )
Hard drives, removable disks, and CDs are ways of storinginformation for computers. They make the process of backup up ormoving data from a computer much easier.
\nNo. A bigger hard disk drive does not usually mean a faster computer. It only means that your computer can hold more data before it crashes. The speed of your central processing unit sometimes called your chip mainly determines the speed of your computer. While other factors enter in, it remains t…he main reason. ( Full Answer )
The most common HDD size is 80gb, they are inexpensive and most rarely fill them. Now days, computers are coming with 160gb and 320gb which is plenty for the average PC user.
first of all good day, my answer in that question is simple. The computer recognized the hard disk drive as a normal. he can be a slave nor a master. thank very much, that is only my opinion.
Hard Disks (or hard drives) are mainly used for Primary Storage. Typically most of the data on the computer, and the operating system, are stored on the harddrive. Without a hard drive or similar long-term storage, you would have to store data in RAM. RAM is volatile (temporary) memory which clears …when the computer is turned off. Whereas hard drives will store data reliably without power, provided the hard drive and computer are functioning correctly. Hard drives may also be utilized as overflow space if the computer runs out of RAM. Which harddrives are much slower (typically 50-100 MB/s) than RAM (1,600-8,000 MB/s) it is also far, far larger. Most harddrives are from 80 GB to 2,500 GB these days. This allows virtually limitless space for RAM to overflow to, and allow the system to keep functioning in the event of a RAM shortage. Computers typically only have 4 to 32 GB of RAM. ( Full Answer )
Yes. You can typically buy an adapter at your local Best Buy or other electronics store to use to connect the drive to your computer via USB.
Yes, a hard drive is more properly called a hard disk drive. They are not the same thing, but a hard disk drive is a type of disk drive, just like a floppy disk drive is another type, and just like a soft armor and hard armor are both types of armor. You can pretty much use "disk drive" and "drive" …interchangeably in computer contexts. The most confusing thing about hard drives is that they contain fixed (non-removable) disks. You don't SEE the disk(s), because they're locked inside, and so you could easily wonder if it's actually a disk drive. Some people use hard drive and hard disk interchangeably, probably because they're not really sure what the difference is. Most of the time it really doesn't much matter much, but it's important to understand that there are other kinds of disk drives: floppy disk drives, tape drives, optical drives (CDs, Blu-ray discs, DVDs, etc.), magneto-optical disk drives (M-O drives) too. All of these tend to have removeable disks, which you can change. The drive stays, but the disks in it can be swapped around at will. They're called hard disk drives because the type of physical disk that spins around inside (the disks their motors DRIVE around) are hard, like an old style vinyl record (metal or ceramic coated with a magnetic material), rather than soft like a floppy disk (plastic with a similar material). Note that flash drives (aka USB drives, aka Pen Drives, etc., more properly called solid state drives) are another of the few drive types that have non-removable disks. They're subject to the same confusion that hard drives are subject to. In other words, a USB pen drive also has a USB disk within it. Generally they have four main parts if you open them up: the drive chip, the memory chip (disk), the USB connector itself, and the circuit board that links them all together. Might help to look inside an old one some time, just to be extra clear about how separate these things really are. ( Full Answer )
A hard drive is the main component that the computer relies on. On the hard drive, the operating system is stored, also includes your pictures, videos, music, documents, etc. No operating system on hard drive? The computer will not work.

It varies enormously; depending on the capacity of the drive, the type of drive and the quality of the manufacture. They cheapest drives, in bulk are only a few dollars each, whereas high quality drives, designed for servers will cost thousands of dollars.
The Hard Disk Drive, or HDD, is typically the main storage device for most computers. The operating system (such as Windows, Mac OS X, or Linux), games, programs and applications, music, movies, etc. are all typically stored on the Hard Drive. Usually, the HDD is the largest storage device attach…ed to a computer. HDDs may be singular or plural- a PC can have many HDDs, but most only have 1. They can also be internal (inside the PC) or external (attached by USB, eSATA, or Firewire). Some may not be attached at all, as wireless HDDs do exist. ( Full Answer )
Partially. The answer is a little complicated as what a computerdoes is governed by a combination of hardware, firmware, andsoftware. Typically the Operating System or Boot Code can be stored on a harddisk drive, so in this way the hard drive tells the computer whatto do. However, there are comput…ers that do not have hard drives or runfrom removable media. In that case the operating system is not runfrom the hard drive. ( Full Answer )

Hard disk is used to store all files and information of your computer including operation system, application program and all of your files, information. if here is no hard disk, all files will no space to store, the system cannot be installed and used. hard disk capacity of the units is MB (megabyt…es) GB (gigabit) TB (1TB = 1024GB), current the most of the hard disk provide 40GB, 60GB, 80GB, 120GB, 160GB, 200GB, 250GB, 320GB, 1024GB (1TB), and 3.5-inch HDD enclosure 500GB, 640GB, 750GB, 1TB of high-capacity, in addition to desktop-like external hard disk capacity even up to 2TB, 4TB of storage capacity. As technology advances, hard drive will be increasing capacity, the volume getting smaller and smaller! ( Full Answer )
Storage of anything that can't be kept in internal RAM. Some examples are: . Databases . The filesystem . OS . Virtual memory . etc. Also the one hard disk is usually used for all of these at the same time.
You create a directory, then get a big thing where you save your stuff onto, then save all you want onto it. Then wait for the hardrive and follow the instructions from there! Hope this helped:D
SATA (Serial Advanced Technology Attachment, Serial ATA) was introduced in 2003 and is the most common technology for hard drive connectivity. Starting with revision 1.0, which transfers data at speeds up to 1.5 Gbps, SATA is now at revision 3 which transfers data at speeds up to 6Gbps. To und…erstand the speeds here is an example; An mp3 song might be 6MB in size. 6Gbps = roughly 600MB per second. SATA 3 can in, effect, transfer 100 of those MP3 songs every second. ( Full Answer )

The exact steps to replace a hard drive depend on the computer you are replacing it in. The general method is to open the computer and remove components until you get to access to the hard drive. Make sure you are grounded so you don't fry anything with a static shock.
a hard disk drive is typically an electro-magnetic device which is used as a secondary storage in many computers. Compared to primary memory, HDDs own a huge data capacity but works slower than other memory devices. Since the technology is not so much advanced like a fast RAM storage, HDDs are low i…n price and it works as a trade off between cost and performance. (i.e. a part of the concept of memory hierarchy) nowadays, HDDs are available at very high data capacity in the range of TBs for PCs. but still they are far better in price compared to a RAM of the same size. - Tharindu Rusira ( Full Answer )
Technically, Yes, though it's expensive and a very precise science. as to go about doing it, I wouldn't recommend it for even some advanced computer technicians.
I'm not sure where it is? But there is a small amount of gold and silver in a computer tower. I just learned that in my computer class just not exactly where at in the computer tower. It's only like $5 to $25, but it might be more now because the price of gold is much higher these days.
That depends on encryption you are using. In any case OS creates partitions and formats it (or specialized software). Next if you have software encryption, than special driver is installed which either encrypted files or whole disk by intercepting read and write operations called by OS. If you have …hardware encryption, then your whole hard drive is encrypted on hardware level. It means that hardware has extra steps before writing or reading information on hard drive.

How do you copy Songs External Hard Disk to computer Hard Disk Drive where it will remain even after disconnecting the External HD from Computer?
Simply connect your external hard disk to your computer. Then select the songs you want to play later, copy them and paste to your computer hard drive. And after disconnecting your external hard disk you can now play the selected songs from your computer hard drive.
Seagate, Toshiba and Western Digital manufacture hard disk drives for personal computers. Over two hundred companies manufacture these druves, but those are the 3 biggest.
Typically hard disk drives can be purchased at any electronics store, or online. You can even view most electronic store prices and products online as well, as most stores have an online web page.
If one deletes a file from a computer and it is no longer in the recycle bin, the data still remains on the hard drive. One an use a file recovery system to attempt to recover the deleted file. When a file is deleted the sector on the hard drive is considered "free space" and as long as other mate…rial has not been saved to that free space it is likely the deleted file can be recovered.

A Sata hard disk drive connects a host adapter to a mass storage device. Some of the main advantages of using a Sata are reduced energy cost, faster transfers of data, and higher signalling rates.
The computer hard disk and CPU have completely different purposes.Your question asks "or", so I will tell you that the hard diskstores data and programs. Having answered that the "or" means Imust not tell you what the CPU does.
A traditional hard disk works with electromagnetism. It uses a writing/reading arm with a electromagnet that willwrite/read data as magnetic fields onto platter(s).
A hard disk is a permanent storage device that (typically) usesmechanical and electromagnetic means to store data onto platters.
