Hard Disk Drives
In a personal computer, a hard disk drive controls the positioning, reading, and writing of the hard disk, where data is stored.

Is 1.0 TB enough hard drive on a desktop computer?
Yes, it is even enough for a NAS.
Of course ti tdepends on what you want to do with your computer. If you will be editing long high definition videos than you want a lot of storage. If you just want to surf the internet you don't need much at all, just enough for your programs.
What is the latest capacity of hard disk?
As of 9/9/9 the Largest capacity consumer drive is 2TB (Terabytes). Current most drive menufactures have a 2TB capacity model available.
*It should be mentioned that there are currently (as of 9/10/09) 3TB EXTERNAL hard drives available for purchase, for as little as $299 USD.
What is the permanent storage put in a computer at the manufacturer?
it all depends on the harddrive size. The size of the harddrive is measured in gigabytes or gigs. Then a number like 160 (thats the size of mine) It also depends if you have an external harddrive. I hope this answered your question.
What is the data access method used to retrieve data by a hard disk?
The hard drive is truly a remarkable piece of engineering. It could be compared to a cross between a record player and a tape recorder.
Metal platters, coated with magnetic material, spin at up to 10,000 RPM's beneath magnetic heads. The heads actually "float" over the platter when the drive is running so as not to scrape the magnetic coating off.
The information is arranged on the hard drive in Tracks and Sectors. A track is one concentric circle, where a sector is a "pie slice".
When you save something to the hard drive, the computer looks at a special area of the drive called the FAT (File Allocation Table), and determines what sectors are currently available to save the data. The heads then are moved over the appropriate sectors, and the information is "Recorded" onto the spinning magnetic platter.
When you read something from the hard drive, the computer first looks at the FAT to see where it is saved, and then moves the heads to read the information spinning on the platters below it.
Since the hard drive is spinning so fast, care must be taken not to submit the drive to shocks or bumps. If you've ever played with a gyroscope, and seen how it reacts (kind of "wobbling" when it is bumped), the same thing can happen with a hard drive. However, that wobbling could cause the heads to make contact with the platters and scrape the magnetic coating. That can lead to the loss of data where it has been scraped off, or even worse, a head "crash", where that scraped material gets caught between the head and the platter, causing a LOT of damage and data loss.
* Note: I know that the simple track/sector analogy goes way back to MFM drives and so forth, but for the sake of simplicity, I wasn't going to get into heavy technical details about interleaving, flexible sectors per track, RLL, IDE, etc. etc. Without going into a crazy level of details, this explanation is valid.
What is the capacity of the floppy disks?
The most common ones most people are familiar with were 1.44MB, but there were many sizes of "floppy disk" from about a hundred kilobytes to a couple hundred megabytes.
Nowadays, the answer is 1.44 for a double sided high density 3.5" floppy disk. This answer is quite different for other types of floppy disks. There are single sided, double sided, single density, double density, high density , 5.25", 3.5", and 8" floppy disks just to name a few of the many, MANY variations.
* low density capacity: 360 kbytes * hi density capacity : 720 kbytes * double hi density: 1.44 megabytes
There are other (rare) formats that can hold more.
What is the function of the jumper on the hard disk?
Jumpers can do a lot of things, some motherboards have many of them. Basically they are a manual switches, that can be closed by shorting them with a jumper cap. Some examples are, jumpers that set the CPU speed, or reset the BIOS memory.
Yes, you can convert a FAT32 to and NTFS disk by formatting it from FAT32 to NTFS. All files will be removed so remember backup. Use Disk Management in XP to format. For devices right click them in My Computer.
Yes if your only looking to save small files such as documents or images.
Why is the hard drive of a computer sealed in an airtight case?
Hard drives use what is called as the disk platter and a head for storing and reading information respectively. The platter are circular disks which hold data and the head read the data off these platters. The head is floating very close to the platters reading and writing data (using magnetism). sometimes,.the head may touch the platter, taking off the aluminum surface coat which actually stored the data, causing data corruption. Also the head needs to freely float without any jerks or air circulation movements. Thus, the hard drive is sealed internally in a air tight compartment. It also protects the platters from dusk, moisture and smoke.
It must be noted that not all hard disks work like this.
In a system that uses a CD drive were the audio wire connects?
There is a data cable,and a power cable that connect the drive to your PC.
Everything is done with the data cable, there is no audio or video wires.
How do you install windows xp onto a totally blank hard drive?
There are two ways to partition a hard drive that I practice without using a third party software.
- The first way is to partition the drive in the set up environment using a windows xp bootable disk. The exact direction are here: http://support.microsoft.com/kb/313348
- The second way is within the already existing xp environment, and those directions can be found here: http://www.d-silence.com/feature.php?id=246

Can you use your old PC as an external hard drive?
Generally, that would be what a server is used for. If you have an old computer laying around, you can probably reformat it and add hard drives, then install either Linux or Windows Home server.
How can you remove viruses from boot sector?
Run Malwarebytes Anti-Malware
Run the anti spyware removal programs spybot
Run Superantispyware
Run a complete scan with free curing utility Dr.Web CureIt!
Also run rootkit revealer.
How do you initialize an external drive?
Plug in the disk you want to initialise In Windows XP/Vista: Go to Start>Run (the search box in Vista).
Type 'mmc' (without quotes).
The Microsoft Management console will appear.
Press Ctrl+M. Select the Disk Management icon from the list on the left, click 'Add>', then 'OK'.
Right click on the disk you want to initialise and select 'Initialise' from the menu.
Follow the prompts.
If unsure, go with the default values.
What is the size of internal hard drive for a Mac book?
Though macbooks vary depending on what a person buys, the three variants of macbooks include 120, 160, and 250 gigabyte of their hard drives. This is just for the plain macbook, not for the macbook pro.
Is a hard disk and a hard drive the same?
Yes, most standard hard disks are mechanical magnetic disks. Magnetic media is more of a general term for a family of disk formats including standard hard disk, floppy disks, and zip disks. In the next few years solid state disks will gradually begin to replace magnetic hard disk media.
What is the name of the hard disk parts?
Outer covering - protection. Disk (single or dual)- stores information written by the writer. Disk motor(measured in rpms) - spins the disk at high speeds. Writer(single, or dual per disk) - wrights information to the disk. Writer motor - moves the writer back and forth between the magnets to write the data onto the disk. Magnets - two high powered magnets that are placed just on the top and bottom (with a little space) to keep the writer free and off the disk. Board (containing power port and data port)- moves the data through wiring before it is moved to the writer.
How many songs can fix on a 1tb external hard drive?
250 3-4 minute songs can fit in 1 GB.
1 TB is 1,536 GB.
So, about 384,000 3-4 minute songs can fit in one TB.
What are the common jumper settings for hard drive configuration?
Primary master and secondary master
Where does the hard drive receives its power?
It depends on the form factor of the disk itself. If it's a 2.5" laptop hard disk that runs off of (E)IDE (about 40-44 pins you'll see when disconnected) then usually it will be powered straight from the IDE bus. If it's SATA or (E)IDE on any other form factor (SATA 2.5" laptop/3.5" desktop or IDE 3.5" desktop disks) then they'll need a dedicated 5/12V power supply that usually can be provided by a computer's power supply unit or via a special power brick (if you're using a SATA/IDE to USB interface).
