Legacy drive setup workflow: After performing a low-level format on a hard drive, what is the next step to prepare the disk for use by the operating system?
-
AFormat DOS partition
-
BInstall operating system
-
CConfigure DMA channel and back-up interrupt
-
DPartition hard disk
-
ENone of the above
Answer
Correct Answer: Partition hard disk
Explanation
Introduction / Context:Classic drive initialization involved distinct stages: low-level formatting (physical), partitioning (logical layout), and high-level formatting (file system). Understanding the correct order avoids wasted effort and ensures the OS recognizes the disk properly.
Given Data / Assumptions:
- A low-level format has just been completed (rare on modern drives, common historically).
- The OS expects a partition table defining at least one usable partition.
- High-level format creates the file system inside a selected partition.
Concept / Approach:
After a low-level format defines physical tracks/sectors, you must create partitions using a tool such as FDISK (or modern equivalents). Only after partitioning can you run a high-level format (e.g., FORMAT C:) to put a file system in place. Installing the OS comes last, after a formatted, mounted partition exists.
Step-by-Step Solution:
Run partitioning utility to create primary/extended/logical partitions.Mark the active partition if required for booting.Perform high-level format on the new partition(s) to create the file system.Proceed with OS installation onto the formatted target.Verification / Alternative check:
Disk management tools should show the created partition table; drive letters mount; a directory structure appears after high-level format, confirming readiness for OS installation.
Why Other Options Are Wrong:
- Format DOS partition: Premature if you have not created the partition yet.
- Install operating system: Requires an existing, formatted partition.
- Configure DMA/interrupt: Not a typical step in standard disk prep.
- None of the above: Incorrect because partitioning is the proper next step.
Common Pitfalls:
Skipping the active flag on the primary partition; formatting the wrong drive; mis-sizing partitions for the chosen file system’s limits.
Final Answer:
Partition hard disk
