Description

NEC D5146H 5.25" MFM Hard Drive This is a vintage, highly collectible 5.25-inch Half-Height (HH) mechanical hard drive manufactured by NEC Corporation in September 1988. • Interface: It uses the legacy MFM (ST506) interface, standard for 1980s IBM PC/XT and AT compatible computers (such as 286 systems) long before IDE or SATA existed. • Specifications: The drive has a 40 MB capacity with the handwritten geometry configuration: 615 Cylinders, 8 Heads, and 17 Sectors. The "H" designation indicates it features an advanced torque motor for head positioning, lowering the access time to 40 ms. • Condition Notes: The label carries an NCR part number (602-0430762) and strict warnings regarding handling—specifically to avoid rotating the external gear and to prevent shock, as these early drives typically require software head-parking before being moved. Highly sought after by retro-computing enthusiasts and hardware collectors due to its age and relative scarcity.
