What is an external hard drive (with pictures) mp electricity bill payment online indore


A hard drive is a computer component that holds data. Every computer needs at least one hard drive to store its operating system, programs and user information. This drive usually is internal, or built into the computer, but as computer systems have evolved and different needs, threats and circumstances have arisen, external hard drives have become more popular. External hard drives usually are used in addition to internal hard drives in order to store more data. They also allow the user to put sensitive, confidential or otherwise important information on them, then disconnect them and store them in secure locations. Physical Characteristics

An external hard drive sits outside the main computer tower in its own enclosure. This portable encasement is slightly larger than the hard drive itself, and it sometimes contains a cooling fan. The external hard drive is connected to the computer via an interface cable, which allows the external hard drive to communicate with the computer so that data can be passed back and forth.

Internet access regularly exposes computers to potential security threats such as Trojan horses, viruses and spyware. It has become increasingly difficult to guard against these threats, even when employing firewalls and antivirus programs. Aside from online threats, multiple family members often use the same system, putting sensitive documents at higher risk of inadvertent corruption or loss. Additionally, the space required for multimedia storage has soared, with digital media files often taking up large amounts of space on a user’s hard drive. All of these concerns can be addressed with an external hard drive. Advantages

A portable or external hard drive allows the user to back up or store important information separate from the main internal hard drive, which could become compromised, damaged or corrupted. Sensitive documents, large music files, movies, images and other backup files can be kept securely and safely on an external hard drive. Another advantage of an external hard drive is that it is portable and operates on a plug-and-play basis so that other compatible computers can recognize the drive as a storage device and can be used to access the files. A user can easily transfer files from the computer to the portable hard drive or from the portable drive to the computer, or programs can be run directly from the portable hard drive.

Using an external hard drive with itunes is a bit more complicated but still relatively easy. In itunes go to options, or preferences (depending on your version) if you look around in there you will find the place it stores your files. (Usually my music/itunes) You could change this to the new hard drive. Then you could go to the advanced tool bar and select consolidate my library. This will copy all of your itunes files from your computer to the hard drive. Now while you have your hard drive connected and turned on itunes will get your media files from it. BUT if the hard drive isn’t on itunes will run the files from your computer. So delete the files that are taking up so much space on your internal hard drive and only run them off of the external one. This is what I am currently doing with my itunes, my bunch of songs where taking up all my valuable hard drive space on my laptop.

First of all I don’t know why you would want to go backward from vista to xp. With the two different versions you will still be able to share whatever you need between them. Running XP will be difficult because XP usually takes control of all external devices (meaning the hard drive it is on) I don’t know what will happen when it does this, but errors will occur. If you look up some information about live linux that can show you some other options (although you would have to find a way to do what they are doing, but with XP). There is a tool called BartPE with is a slimmed down version of XP that you can run off a flash disk, so you should be able to run this off a hard disk.

I don’t know what happened when you tried to backup your data. First thing you do, whenever you have a problem is shutdown the pc, not just sleep, full shutdown. Turn off your surge protector so the pc isn’t getting any power. Turn off the hard disk too. Now restart and see if your problem is fixed. If this doesn’t work, you could try formatting the disk. I don’t want to go into this here, because somebody will misread my post and erase there whole computer and be pissed at me. But if you look it up you can find tons of info on it.
