Hard Disk Partitions

Leave a Comment / CHFI / By

Hard Disk Partitions refers to the creation of logical drives for effective memory management and a partition is the logical drive for storing the data. Hidden partition created on a drive can hide the data. The inter-partition gap is the space between the primary partition and the secondary partition. If the inter-partition drive contains the hidden data, use disk editor utilities like Disk Editor to change the information in the partition table. Doing so will …
