What else can I help you with?
If a floppy drive is divided into tracks which are divided into sectors How large is each sector?
512 bytes of data
A floppy drive is divided into tow tracks which are divided into sectors How large is each sector?
about 512 bytes but when you format a disk you can change the size of each sector
How large is each sector on a hard drive?
A sector has a fixed size; it will always be 512 bytes. A cluster can be as small as one sector, and can be as big as it needs to be.
How do you calculate the capacity of a floppy disk?
To calculate the capacity of a floppy disk, you need to know its specifications, including the number of sectors, the size of each sector, and the number of tracks. The formula is: Capacity = Number of Tracks × Number of Sectors per Track × Size of Each Sector. For example, a standard 3.5-inch floppy disk typically has 80 tracks, 18 sectors per track, and a sector size of 512 bytes, resulting in a capacity of approximately 1.44 MB.
Who made virus?
The first virus was made in Chauburji, Lahore, Pakistan, 1986Two programmers named Basit and Amjad Farooq Alvi, .replace the executable code in the boot sector of a floppy disk with their own code designed to infect each 360kb floppy accessed on any drive. Infected floppies had " Brain" for a volume label.
On a floppy disk drive how many bits are used for each entry in the FAT?
12 Bits
Do you need to format a disk each time you use it?
No. Floppy drisks do not need any formatting at all. Just pop it into the floppy drive and that's all you need to do.
What is a formatted floppy?
A floppy disk where everything on it has been removed / deleted, to clean it up for new stuff. In order to format a floppy, you need to write blank tracks onto it, each containing the necessary sectors, sector headers, and inter-sector and intra-sector gaps. This is done using a special command of the floppy controller which writes a full track at a time. You then need to write data to the floppy to provide the logical file system. In the FAT 12 file system, that consists of the boot record, the file allocation table, and the root directory. If you intend to boot from the floppy, then you need to write the rest of the boot record, and the required operating system files, usually IBMBIO.SYS, IBMDOS.SYS, and COMMAND.COM. If the floppy has been previously formatted, it is possible to skip the physical format part where you write the tracks - just rewrite the file allocation table and the root directory, and the system files if needed, and you will delete all of the files and directories on the floppy. Often, however, it is better to do the complete format, particularly if you are using the floppy in a different drive.
Which drive letter will the floppy drive have if installed in the middle connector?
So long as the floppy drive is set to cable select mode it will come up as B:\. Otherwise it will be be primary (A:\) or secondary (B:\) depending on jumper settings on the reverse of the drive. Make sure if fitting 2 floppy drives you have them set on different jumpers to each other or both are set to cable select mode or neither drive will work.
You have got a computer problem When you start up it says primary disket 1 failure and cover was recently removed What shall you do?
Your system is having problems reading from either the floppy drive or a hard drive. Primary Diskette would be a floppy. If this is the problem then check whether or not there is a floppy in the drive. If not then check the cabling inside the case for disconnected connections. Primary Hard Disk would he a hard drive. Check the connections to the hard drives, and the master/slave/cable select settings on each of the hard drives.
What is hard sector and soft sector in floppy disk?
A hard-sectored floppy disk (5.25") has timing holes (typically ten) drilled through the disk at evenly-spaced intervals around the disk at the same radius as the index hole (which is one hole drilled between two of the timing holes). The timing holes indicate to the disk reader / writer / controller where the sectored are located on the floppy disk. A soft-sectored floppy disk has a single index hole and no timing doles drilled in it. The spacing of the sectors is determined by set time intervals from the passage of the index hole as it rotates. For example if there are ten sectors each would be spaced at 1/10 of the time it takes the disk to rotate. The controller for a soft-sectored disk drive must be able to control speed and measure time more carefully than a hard-sectored disk drive. A soft-sectored disk can't be read or written by a hard-sectored disk drive (and vice versa) unless the disk controller has been written to deal with the different number of holes.
Data is written to and read from a floppy disk via a magnetic mechanism in the floppy drive?
Data written on or retrieved from a floppy:The floppy cover has a window with a spring-loaded metal shutter. The shutter is pushed back which uncovers the window when it is inserted into the disk drive. The drive rotates the disk inside its protective covering at a speed of 300 rpm. Read/write head contacts its exposed surface through the window.Recording is done magnetically in concentric circles called tracks. Data is read or written serially in bits on the tracks within a given sector.Microcomputer disks use sector organization to store and retrieve data. In sector organization, the recording surface is divided into pie-shaped sectors. The number of sectors depends on the density of the disk. Each sector is assigned a unique number. The sector number and track number are all that are needed for address on a particular disk-face surface. The disk address represents the physical location of a particular file or set of data. An access arm containing the read/write head is moved under program control to the appropriate track. Data are read or written when a sector containing the desired data passes under the read/write head.By Khushal Khan Nasar......
