You are formatting a single hard disk for a Linux install.
What is the maximum number of primary partitions you can create?
Answer: four
Explanation:
Generally in one system we can connect four (4) Physical Harddisks.hd0 /dev/hda Primary Master
hd1 /dev/hdb Primary Slave
hd2 /dev/hdc Secondary Master
hd3 /dev/hdd Secondary Slave
The explanation refers to the number of IDE hard disks that can be connected to a system, NOT to the question posted. The answer ‘four’ is correct, however, the explanation should be more to the effect of – “A primary partition is a type of Master Boot Record partition that’s defined in a data structure contained on the hard disk’s partition table in the MBR. An MBR disk can hold only four primary partitions.”
