Capacity and interface

The Maxtor DiamondMax D540X is a 40 GB internal hard drive built for desktop and enterprise storage. It uses a 3.5 inch form factor and connects through an IDE Ultra ATA/100 interface. The drive suits systems that still require legacy parallel ATA connectivity.

Deciding specification

The IDE Ultra ATA/100 (ATA-6) interface is the single detail that determines compatibility. Motherboards or controllers must provide a 40-pin IDE port supporting this standard for the drive to function.

Installation notes

The unit measures 1 inch high, 3 inches wide and 5.8 inches deep, weighing approximately 1.27 lb, so it fits standard 3.5 inch drive bays. A 40-pin IDE cable and a Molex power connector are required. Jumpers must be set to master, slave or cable select to match the host configuration. Common issues include incorrect jumper placement, bent connector pins and BIOS limits that prevent the full 40 GB from being recognised.
