You work as the Network Administrator for McNeil Inc. The company has a Unix-based network. You want to fix partitions on a hard drive. Which of the following Unix commands can you use to accomplish…

fdformat is used to perform a low-level format of floppy disk devices, not to manage hard drive partitions.

exportfs manages NFS (Network File System) export entries, controlling which directories are shared over the network, and has no role in partitioning.

fsck (file system check) scans and repairs file system integrity errors on an already-partitioned device, not the partition table itself.

fdisk is an interactive command-line utility that directly manipulates the partition table of a block device, allowing an administrator to create, delete, resize, and change the type of partitions on a hard disk. It operates on the raw partition structure and is the correct tool when the goal is to fix or reconfigure partitions. On modern systems it supports both MBR and, via gdisk/parted, GPT partition schemes.
