Underneath are the commonly asked Hard Disk Drive (HDD) interview questions and Hard Disk Drive (HDD) jobs role which can make you feel relaxed to face the interviews:
Question 1. Explain Landing Zones And Their Technologies?
Question 2. Explain The Different Ways Of Hard Drive Failure?
A hard drive may fail due to multiple reasons. Some of the common causes are:
Question 3. What Is Head Crash?
This is caused when the read / write head comes in contact with the platter. This can cause the area where it has come in contact to lose data.
Question 4. What Is Bad Sectors?
The platter in a hard drive is split into minute areas known as sectors. Sometime certain sectors might become faulty, this does not affect the entire drive.
Sometimes the head of the disk is not able to take off, it tends to stick to its position. This phenomenon is known as stiction.
Question 6. What Is Bearing And Motor Failure?
After prolonged usage the hard disks motors or bearing tend to worn out hence not allowing normal disk performance.
Question 7. What Is Circuit Failure?
The hard disk become inoperable if any of its circuitry malfunctions.
Question 8. Explain Power Consumption Statistics Of The Hard Disks?
Question 9. Explain The Different Types Of Disk Interfaces Used In Computers?
There are various interfaces through which hard disks connect to the computer.
Legacy Bit Serial Interfaces: They are the oldest form of interfaces which used two cables to connect the disk to a controller. One cable was used for data whereas the other is used for control. In addition to the above cables a power cable was also required to provide power to the disk.
Modern Bit Serial Interfaces: In these types of interfaces the disk is connected to a host bus interface adapter using a single cable. In addition to this cable a power cable is also used to power the drive. Some of the modern bit serial interfaces are as follows: Fibre Channel, Serial ATA and SCSI.
World Serial interfaces: They are similar to modern bit interfaces, these interfaces make use of a cable for data and control. Some of the common world interfaces are as follows: IDE, EIDE, SCSI etc.
Question 10. Explain The Purpose Of Interleave?
Question 11. What You Understand By Access Time. Explain Different Types Of Timings In A Hard Disk Drive?
The access time is the time taken by the disk to read data on it and it is directly related to the nature of the platter speeds and the moving heads.
Question 12. Explain The Various Form Factors In Which The Hard Disks Are Available?
Question 13. What You Understand By Formatting In Reference To Hard Disks?
Generally the controller determines how the hard disk is presented to the host system.
Question 14. Which Errors Can Be Handled By Hard Disks?
There are various ways in which modern hard disks handle errors.
Question 15. How Data Is Read And Written On A Hard Disk?
Question 16. Explain Structure Of A Hard Drive?
Hard disks in them contain various components such as Platter, Spindle, Actuator, power connector, Jumper block, IDE connector etc.
Question 17. What You Understand By A Hard Disk And How Are They Classified?
Hard drives are usually devices that can be used for storing data and to retrieve it. They are composed of one or more than one rigid disc that rapidly rotates.
Question 18. Explain What Is Meant By Cross-compiler?
A program runs on one machine and executes on another is called as cross-compiler
Cross compiler programs are written for embedded systems(usually) but run on normal PCs to gauge their performance. Later on, they are ported to embedded systems.
Question 19. Explain Which Segment Is Used To Store Interrupt And Subroutine Return Address Registers?
Stack Segment in segment register is used to store interrupt and subroutine return address registers.
Question 20. Explain How Many Logical Drives Is It Possible To Fit Onto A Physical Disk?
Maximum of 24 logical drives. The extended partition can only have 23 logical drives.
Max of 24 partition from "c" to "z"
Question 21. What Is Mbr Located On The Disk?
Main Boot Record is located in sector 0, track 0, head 0, cylinder 0 of the primary active partition.
sector 0, head 0, cylinder 0,
Question 22. Explain If You Are Getting In Disc Boot Error. At Initial Stage What You Need 2 Check. Please Detail In Steps?
Question 23. Explain Which Is The Tool Used To Connect The User And The Computer?
Interpreter is the tool used to connect the user and the tool. And the operating system is used to connect the user and computer.
Question 24. Explain And Give Example For Non-maskable Interrupts?
Trap is known as Non-Maskable interrupts, which is used in emergency condition.
This has the highest priority
Question 25. Which Logic Calculations Are Done In Which Type Of Registers?
Accumulator is the register in which Arithmetic and Logic calculations are done.
Question 26. Explain Sim And Rim Instructions?
SIM is Set Interrupt Mask. Used to mask the hardware interrupts. RIM is Read Interrupt Mask. Used to check whether the interrupt is Masked or not.
Question 27. What Is Hard Drive (hd)?
A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read/write heads that float on a film of air above the platters.
