Floppy Disk Drives
Floppy disks are an outdated form of magnetic data storage. Questions about floppy disk drives and floppy disks themselves belong here.

How does a computer find data stored on disk?
It uses tracks and sectors to find certain pin points on where the data is. Some of the spots are reserved for certain files.
What are the error codes of floppy drive?
It means a bad spot was detected on the floppy when your computer tried to write or read data from the disk. Most of the time, the drive head that reads the data has become dirty, but sometimes there is physical damage. Rotate the disk in the sleeve. If you see scratches, dents, or folds on the surface, the disk is no good.
There is a floppy disk cleaning kit that can be used to clean the head. They have a white fibre disk in the floppy, instead of the plastic disk with brown magnetic coating.
To use a cleaning kit. Put a squirt of the head cleaning solution in the slot on the cleaning disk, insert it, and access the disk a couple of times (i.e. use the DIR command at the dos prompt). If you have no head cleaning solution, use rubbing alcohol. Don't saturate the disk, just make a wet spot. The disk will wipe the head wet/dry as it rotates.
It is possible to mark bad sectors and do data recovery on a floppy if necessary, but it requires an old copy of the Norton Utilities and some know how to do it.
Good luck.
How does system clock speed affect a computer speed?
There are several numbers and terms here that must be understood before that question can be answered. Many computer processors use a front side bus to communicate with the north bridge and RAM. The speed of that bus determines how quickly the CPU can read and write to memory as well as other peripherals. For ease of synchronizing those systems, many CPUs will set their Core processor speed to a multiple of that FSB. The actual "speed" of your CPU will be determined by the FSB * multiplier, but most CPUs will actually execute several instructions per core clock "tick." It's very difficult to determine how fast a computer will be compared to another one based solely on the clock speeds.
How do you dispose of floppy discs?
There is no special care, just put them in a plastic bag and dispose them like other common parts.
Which disk drive standards uses an 80-conductor cable?
The drive interface that uses an 80-conductor ribbon cable is IDE. IDE stands for Integrated Drive Electronics, an interface commonly used to connect hard disks and optical drives to computers.
Why does Designating the Hard Disk as the only bootable device increase system security?
Because alternative media won't boot with alternative operating systems.
How do you take care of your Disc an Diskette?
Keep it away from Magnets.
Save it from extreme temperatures.
Always store vertically in box.
Do not touch surface while inserting or removing it.
Never leave the disk in the PC after finishing the job.
Avoid over use of the disk otherwise it will not last for more than 6 months
Do not mix disks to be used everyday with those used for long.
Never put any heavy object on disk.
Never carry in loose bags or in pockets.
Never use clips/staples to hold disk.
The floppy cable has a twist in the cable.
Why floppy disk are not a part of a computer system nowadays?
Because floppy disks could only hold tiny amounts of data, only above 1Mb, where as now days memory sticks can hold over 16Gb, over 16,000 times more data. They are also bigger in size too. Most documents and files wouldn't even fit on a floppy, such as MP3 files (songs) which are about 4Mb.

How much storage does a floppy disk hold?
The capacity of the most ubiquitous floppy is 1.44 MB. Floppies in other capacities have also been made.
Explain why you would format a floppy disk?
Theoretically - it erases all the data on the disc - However...
On a floppy disk, there is a 'reference track' which holds details of each file on the disc (name, start point, size and end point) When you format a disc - the computer ONLY erases the details on this track. Without the reference track information, there is no way for the computer to locate a file.
Why floppy disks are not often used for data base?
A database to function effectively needs high speed access to stored data.
Floppy disks CAN be sued for storing a simple database, but there are some severe limitations:
- slow access speeds means slow database response, especially if the computer cannot hold the entire database in local memory for sorting, etc.
- severely limited storage space may limit the database formats available, as many newer database have considerable data storage overhead
- constant read/write operations can wear floppy disks causing them to fail fairly quickly
- data cannot easily be shared with more than one user
Older databases, such as Paradox, would happily use floppy disks for storage. Problems are likely to occur if the same was attempted with a modern database, such as MySQL.
Write a short note on magnetic disk?
Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drive.

What is magnetic disk storage capacity?
Tape remains a viable alternative to disk in some situations due to its lower cost per bit. This is a large advantage when dealing with large amounts of data. Though the areal density of tape is lower than for disk drives, the available surface area on a tape is far greater. The highest capacity tape media are generally on the same order as the largest available disk drives (about 5 TB in 2011). Tape has historically offered enough advantage in cost over disk storage to make it a viable product, particularly for backup, where media removability is necessary.
How much data can be stored on a 3 and 1 2 inch floppy disk?
5.25" floppy disks were available in a large number of storage capacities. These include 110 KB, 360 KB (DD), 720 KB (QD), and 1.2 MB (HD). There were also a couple non-standard formats that went all the way up to 100 MB.
Why are floppy disks used for temporary storage?
Data can be easily loss when floppy disc is placed near a source of magnet or radio wave interference.
What will the protoplanetary disks eventually become?
That depends what the disk is forming round. If it is a large black hole it will form a quasar, if it is round a star, it will form planets (a solar system).
Where can you download pictures?
If question is meant to be aimed at a basic level, you could simply go onto the image search engine: http://images.google.com/imghp?
from there search the wanted image, then click on it...maximis...then save as...and then wherever you want to save on your computer!
What is pen drive as processing device?
No. Its is just a storage device. All the processing is done my the CPU.
eNjOy!!
