After performing a low-level format on a hard drive, what is the correct next step in preparing it for use in a PC?
-
AFormat DOS partition
-
BInstall operating system
-
CConfigure DMA channel and back-up interrupt
-
DPartition the hard disk
-
ENone of the above
Answer
Correct Answer: Partition the hard disk
Explanation
Introduction / Context:Disk preparation follows a sequence: physical preparation, partitioning, file system creation, and OS installation. Understanding the correct order avoids boot failures and configuration issues, especially with legacy PCs.
Given Data / Assumptions:
- Low-level format (LLF) or factory initialization has been completed.
- We need the next logical configuration step to make the drive usable.
Concept / Approach:After LLF (or using modern drives as shipped), you must create one or more partitions to define logical volumes on the disk. Only then can you high-level format those partitions with a file system (e.g., FAT, NTFS) and install an operating system. Installing an OS without partitions or skipping the high-level format will fail.
Step-by-Step Solution:Complete LLF or accept factory initialization.Use a partitioning tool (e.g., FDISK, Diskpart) to create partitions.High-level format the new partition(s) with the chosen file system.Proceed to install the operating system onto a formatted partition.
Verification / Alternative check:All standard OS installers (DOS/Windows/Linux) either require or offer partition creation before formatting; documentation confirms the order: partition → format → install.
Why Other Options Are Wrong:
- Format DOS partition: Occurs after partitions are created.
- Install operating system: Must follow partitioning and formatting.
- Configure DMA/interrupt: Not a typical disk prep step.
- None of the above: Incorrect because partitioning is correct.
Common Pitfalls:Confusing low-level formatting with high-level formatting; they serve different purposes and occur at different stages.
Final Answer:Partition the hard disk
