How many hard disk can connect system?
It all depends on your motherboard and case. I can have 8 drives in my case, but with my motherboard I can only have 8 SATA connections. So if you want an optical drive you have to sacrifice a HDD. However with HDD's being as cheap as they are you shouldn't need too many.
What is the maximum number of times a hard disk can be formatted?
You can format a hard drive continuously until the end of its life. Formatting is not any different than regular use.
And formatting is nothing but writing the hardisk sectors into value zero and its a myth that harddisl life reduces
Every harddisk has different life , you can formatt the hard disk according to the hard disk , to check this , visit the web site of the company of hard disk .
An IDE cable connects a hard drive or CD drive to the main board of the computer.

How much memory does AVG antivirus take up on your computer?
It should take about 8 or more, but i like it because its not a huge program like avast or avg and other ones.
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 method of storing data on two or more hard drives that work together?
method of storing data on two or more hard drives that work together?
Is a hard disk drive input or out put?
A hard disk drive (HDD) is neither an input nor an output device. It is a Storage Device. It helps to store the data in a Non-Volatile form (i.e Data stored in Hard Drive is not lost even after it's power source removed) and data can be retrieved at any time by enabling power for the Hard Drive.
Where can I purchase portable external hard drives?
Some great places to purchase cheap external hard drives are Amazon, Best Buy, Wal-Mart, Fry's Electronics, and Office Depot. Make sure to check out coupon codes for extra deals at these retailers.
Will replacing your hard drive get rid of a virus?
it should, but a better option would be to get a good antivirus program (AVG is my recommendation). Don't bother with Symantic or many other 'top-sellers' because they don't catch much and can fix even less.
What are the advantages of a hard disk drive?
Although many times slower than system memory (RAM), hard-drives provide extremely large storage capacity and are cheaper to produce (byte for byte). Also, RAM requires electrical power to maintain state (volatile memory) whereas hard-drives will maintain state without any power (non-volatile memory); we only require power to change the state.
When was the invention of the compact disk?
The compact disc is a spin-off of the much less successful Laserdisc technology. In 1979, Sony and Philips Consumer Electronics set up a joint task force of engineers to design a new digital audio disc. The task force, led by prominent members Kees Schouhamer Immink and Toshitada Doi, progressed the research into laser technology and optical discs that had been started by Philips in 1977.
What is the difference between a boot partition and system partition?
Basically the system volume is required to start up, and the boot volume contains the OS.
From http://support.microsoft.com/kb/314470:
The system volume refers to the disk volume that contains the hardware-specific files that are needed to start Windows, such as Ntldr, Boot.ini, and Ntdetect.com.
On computers that are running the Intel x86 line of CPU processors and later versions, the system volume must be a primary volume that is marked as active. This requirement can be fulfilled on any drive on the computer that the system BIOS searches when the operating system starts.
The system volume can be the same volume as the boot volume. However, this configuration is not required. The boot volume refers to the disk volume that contains the Windows operating system files and the supporting files. By default, the Windows operating system files are in the WINDOWS folder, and the supporting files are in the WINDOWS\System32 folder.
The boot volume can be the same volume as the system volume. However, this configuration is not required.
There is only one system volume. However, there is one boot volume for each operating system in a multiboot system."
HDD stands for Hard drive disk. The HDD is what all your files are saved to. It a double sided disk that is build to be read at extremely high speeds.
First check if you could alter the boot sequence in your bios. Power up your computer, after the memory test, take note of the line normally at the bottom screen similar to "Press Del to enter setup" and do it (others are Function keys like [F1]). At BIOS screen locate where the boot sequence is and set your CD ROM to boot first before your hard drive(HD) and floppy disk(FD). Save and exit, restart and install.
Older BIOS do not have this feature so your stuck with a FD, you could:
1. The easy way, download a Win2000 installation boot disk image, create the boot disk, boot up (if it boot form HD instead, set up BIOS to boot from FD first as describe above) and install.
2. The hard way, create a boot disk from a computer with Win2000 installed. Go to [Start][Programs][System Tools][Backup] and create an Emergency Repair Disk(ERD). In your PC, boot up from ERD, select Command prompt only from boot menu, navigate to your Win2000 CD, open the directory i386 and run WINNT.EXE.
Explain the working principle of the hard disk drive?
A hard disk uses platters, round discs that are coated with a special media that is designed to store data in magnetic patterns. These discs rotate so that heads, electromagnetic read/write devices, can either record data onto the platters or read what the platters already contain. Each platter has tracks which is then broken down into sectors which is where pieces of data is actually recorded.
How do you reset your hard drive?
Formatting, there's no easier way to clean a Hard drive as new like formatting
Do people use floppy disks today?
I still use floppy disks for backing up some small files, like Word Documents, Text Files, and small "WAV file sound effects when I don't have any CDs or my flash drive is full.
I still have some old DOS games on floppy that I still play sometimes, though I have them backed up on CD, but I still play the games on Floppy if I can't find the CD.
I also maintain an Emergency Boot Disk, in case my computer crashes or gets hit by a virus and I need to go into DOS to resurrect the computer.
My School has older computers in the Social Studies computer lab that has computers with floppy disks, but I've never used them, I have a Pen drive for that! But I've seen the School IT guy use them to keep these old machines going.
My current Workplace has a few older printing presses that need to be "calibrated" using 4 unmarked floppy disks, in order, or the margins will be off and that docked from your pay. Luckily they copies of copies of copies of the original disks and they are different colors, so they always go Yellow-Blue-Black-Grey, Yellow-Blue-Black-Grey, etc.
The U.S. Government has a protocol that sensitive, classified military documents, such as Nuclear Defense Information, that was written in the 1980s, when floppy disks were the only way to distribute computer information. It would cost so much to transfer all the information to a more modern format, dispose of the old disks and write new protocol that they continue to use floppy disks to distribute this information in 2010 as they did in the 1980s.
There are a lot of older technology still in daily use that requires the use of floppy disks, like industrial equipment and cash registers. I went shopping early at a thrift store (shortly after they opened) once and I had to wait for them to boot the register from 3 floppy disks to buy some clothes, this was in 2008, too!
I remember saving some songs I had composed on an electric keyboard using a integrated floppy disk and could play them as "MIDI" files either on the keyboard or on my computer! But that was back in 2003.
Older digital cameras store their pictures on a floppy disk, also. Most of those cameras are of better quality than the modern, cheap flash-based digital cameras, film-like without the film. Though many of these have been abandoned in favor of new, flsh-based cameras.
Many Developing and Third-World countries use older, obsolete computers that have no other way to transfer and store data than floppy drives, after the developed world deemed them to be "obsolete" and were considered "junk" their still serving Latin America, Africa, Asia and the Islands as daily work-horses in homes, schools, hospitals, businesses and government offices.
As you can see floppy disks are still used, just usually as a legacy system, once all these technologies clunk out, they will be obsolete.
Which is the best first step to protect important data on your hard drive?
Create a disk backup of your hard drive so that in case of a hard drive failure, you can restore your computer to the exact state prior to the failure. NovaBACKUP Professional will create system images, exact backups of a disk drive sector by sector, allowing you restore backups to a computer when the contents of the entire computer are lost.
How do the portable hard drives work?
Portable hard drives work by interfacing with whichever computer they are connected to. In most cases, this connection is established by USB. Once the portable drives are connected they allow the user access to the data contained on it and the drive's storage capacity.
What is the purpose of optical disk drive?
A device for reading discs on which data is stored. They use a light laser which detects bumps and dips on the surface of a disc. these bumps and dips make up binary code which is interpreted by a computer of some sort. Optical drives include CD / DVD / Blu-Ray Disc readers or writers, as well as the already obselete HD DVD players
Can you hook up an external hard drive to your Blu-ray player and watch movies?
No. Although the maximum data transfer speed of blu-ray discs is much higher than that of DVD's, it's speed is much slower than a standard HDD (72MBit/sec compared to better than 1GBit/sec) and the writing speeds are slower, and seek times even slower. Using a rewritable blu-ray disc as a hard drive would be a very bad idea, indeed.
How can you restore Hard Drives back into your computer?
I bought a 500 GB Seagate external hard drive, and I was going to FAT32 format it so It could be used with a PS3. Unfortunately, I deleted the entire partition off of it, and now it no longer is recognized as a mass storage device. It will come up as "Portable" under my devices and printers, but I don't know how it can be changed back to it's original state, so I could still use it. Any help?!
