Why hard disk is a magnetic disk?
Common hard disks with read/write heads are magnetic storage.
The newer SSD (solid state drive) hard disks are not magnetic because there are no read/write heads. Solid state means no moving parts.
SSD drives are labeled as such so you know what you are buying.
Hich type of drive is installed in a 5.25-inch bay?
These bays contain CD Drives/Burners, or DVD Drives/Burners. Although Hard drivers typically go in one of your 3.5 bays, there are braces you can buy to fit one in a 5.25 bay. There are also some Audio pre-amps that can fit into these bays.

How can you tell how many partitions your hard drive has?
You will need to open up the disk management window on you computer. To do this open up the control panel and search for "partition" then click the link that says "Create and format hard disk partitions". From here you can view and modify all the partitions on any disk on your computer.
What is the difference between a physical drive and a partition?
The terms partition and volume are often interchangable and for most purposes the end user doesn't need to understand the difference. There is one however, and this is that partitions are physical separations on the hard drive, often but not always created by the user during installation of an operating system. Volumes on the other hand are logicalseparations of the hard drive. The difference for all intents and purposes is usually the same, but that logical systems of any sort only work within the context of the OS that is being used, where as physical systems will be permanent and recognized by any software.
Computer temporary and permanent storage devices?
Temporary storage is ram, or memory, reason it is temporary is that when you switch the computer off, all information that was stored in memory is now gone.
Permanent storage would be the original type of ROM. It was written to once and could never be changed. That was mainly used for BIOS instructions. While hard drives are non-volatile, meaning they don't need power to retain their memory, they are not permanent.
Nonvolatile storage is hard drives (both internal and external), CD's, DVDs, floppies, USB devices (including flash memory), because data that is stored on these devices remain there until physically changed, or deleted. The data is not lost when the power is turned off.
How do you remove compressed old files?

How do you backup computer to external hard drive?
It depends on the operating system that you are running. In newer operating systems there is normally a backup utility. However, most new hard drives have a method of cloning the hard drive to the new disk. Most new drives come with a cd. Just pop it in and follow the prompts. If not, you can download freeware versions off of the internet. Try downloads.com

How do I change the hard drive on a laptop?
Power down PC, unplug power. Open the PC, determine type of hard drive connection, most likely IDE. Buy similar drive.
If your old hard drive is bad, remove old HD (need screwdriver). There should be a diagram on both hard drives showing where to place the jumper. Look at this and then place the jumpers on the hard drive, matching the new one to the old one (usually located in the back by the ide/sata and power plugs) to match the diagram. Cable select is usually the right choice especially if there is only one drive on a cable with only one connector at each end.
Recomended drive: 7200 RPM or greater, 2MB Cache or better
Make sure you get the same type hard drive - PATA (IDE) or SATA - as you old one, unless your motherboard does both.
While your case is open, blow out the dust. It improves circulation and can add to the life of your computer. Also make sure all the fans are working. Leave the case side open and turn it on without touching the inside. All the fans should come on, assuming you have a name brand computer (read: bottom-line for company) without thermostat controlled fans.
The first part is a matter of cloning the hard drive (assuming you are not just moving the disk from one computer to another). Otherwise the process is known as a repair installation where you will need the bootable CD with the OS to fix the old hard drive so it works in it's new home hardware.
What keeps data when a computer is running but loses the data when it is off?
Computer cannot loose data when is turn off or it is off.This may happen if the computer is infected by a virus.This may also happen if the drices are faulty and do not store data properly.Actualy the data sved on hard disk is always saved there you can run that hard disk in other computer to verify if your computer crashed.
What is maximum file size in FAT 32?
The maximum disk size is approximately 8 terabytes when you take into account the following variables: The maximum possible number of clusters on a FAT32 volume is 268,435,445, and there is a maximum of 32 KB per cluster, along with the space required for the file allocation table (FAT). You cannot format a volume larger than 32 gigabytes (GB) in size using the FAT32 file system during the Windows XP installation process. Windows XP can mount and support FAT32 volumes larger than 32 GB (subject to the other limits), but you cannot create a FAT32 volume larger than 32 GB by using the Format tool during Setup. If you need to format a volume that is larger than 32 GB, use the NTFS file system to format it. Another option is to start from a Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me) Startup disk and use the Format tool included on the disk.

What is the typical storage capacity of an external hard disk drive?
It depends on the model you buy. I've seen models that hold 1 TB (TB is a Terabyte, which is a 1000 gigabytes). You can easily find other models that hold about 800 GB, especially at Future Shop. Obviously, the models that hold more will cost more, which adds up to about $120.00 if on sale (I saw a 1 TB model at Future Shop that costs this on Boxing Day, meaning it would probably be like $160.00-$200.00 without a sale).
How long will pictures last on a external hard drive?
depends on the type of drive, but as long as the drive is kept away from magnets and at the proper temperature and humidity it should last a decade or two.
Which companies make 4TB hard drives?
The 2TB external Drives are run by power adapters as they're too big for USB ports. Iomega prestige is priced at å£149 and can be vertically mounted. Lacey is different in that it is a black glossy box and is å£180.
How many pictures and movies can 500gb external hard drive hold?
A 500GB hard drive can hold 500GB of data (although in reality slightly less is available for use as the formatting of the disc uses some space). This equates to around 800 albums (in mp3 format), or 150 movies, or 10,000 photographs or any combination of such files.
How do computer hard drives function?
A 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.
