What controls the interface between the hard disk and the system bus?
disk controller
What does it mean when your computer says hard drive not found?
The best way, I think to answer that is to define what a computer (or in this case the motherboard of the computer) needs to find or identify a hard disk. A hard disk needs a power source, a connector to attach it to the motherboard, and a controller to talk to the microprocessor of the computer. If any of these things fail the hard disk will not function and the computer will not recognize it. In general when you see the message "hard disk not found" its because the computer can't recognize the hard disk. This can be from a bad cable (that connects the hard disk to the motherboard), no power to the hard disk, or a failed controller. In my experience, its usually a bad cable but there are times when the hard disk itself will fail. Generally, hard disk cables are far more fragile than hard disks.
Which IRQ does the hard disk controller commonly us?
6
What is the advantage of using a disk controller to control the hard disk?
The use of a separate disk controller frees the CPU to perform other tasks. In particular, the disk controller can manage DMA transfers, which otherwise would have to be done by the CPU. The disk controller also manages the movement of the disk head and reading or writing of the data on the disk. Again, without the disk controller, the CPU would be forced to perform these operations.
Where the formatted data go from Hard Disk when you format the Hard Disk?
The data is still there. When you format a disk you're just telling the hard disk controller that the disk is effectively empty and it's okay to overwrite any data that may be on it. This is why "undelete" programs work.
What term is used to descibe disk mirroring when each drive is connected to its own hard disk controller?
Drive Duplexing.
How many disk are present in one hard disk?
Usually only one.
What can hold the most information on a computer?
Usually a hard disk or solid state disk.
What must happen before any data can be read or written on a hard disk?
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
What is the function of the hard disk card?
a 'hard disk card' could refer to a PCI, PCI-E controller card for a computer, or a circuit board on the hard drive, or a solid-state drive (which is just one circuit board).
Does a hard drive consists of platters?
The hard disk drive platter is used to store magnetic data or information that comes from the hard disk drive, where they are stored. The hard disk drive can contain one or more hard disk platter.
Can a hard disk read information quicker than a DVD disk?
Usually much faster
