Applications
The WD400EB is a parallel ATA desktop hard drive from the early 2000s, the era when IDE/PATA was the dominant desktop storage interface before SATA became standard around 2003–2005. Drives like this were widely used in desktop PCs, entry-level workstations, and OEM systems from manufacturers including Compaq, Dell, HP, and IBM. They are still sought out today for repairing and maintaining legacy desktops, embedded systems, and older industrial PCs that require IDE storage. The 40-pin ATA bus supports standard Master/Slave/Cable Select jumper configuration, readable from the jumper guide on the drive's PCB. This particular unit also carried Compaq and Dell OEM part numbers, meaning it was sourced and validated for use in those manufacturers' systems, making it an exact replacement for machines that originally shipped with this drive.
