Seagate ST380012A 80GB IDE Ultra ATA100 3.5" 7200RPM internal hard drive

Legacy IDE Storage

The Seagate ST380012A is an 80GB 3.5 inch desktop internal hard drive built for systems that still use the IDE Ultra ATA100 interface. It spins at 7200RPM and arrives as a bare drive without cables or mounting hardware. This capacity suits vintage PC restorations or industrial equipment requiring a direct PATA replacement.

Compatibility Fit

It suits builders repairing older desktops, servers or embedded devices that only accept a 40-pin IDE connection. Buyers whose motherboards lack an IDE header or who need larger capacities for modern workloads should look at something else. The refurbished condition means the unit has been tested but shows prior use.

Deciding Specification

The IDE Ultra ATA100 interface is the single specification that decides whether this is the right part. Only systems with a matching 40-pin PATA controller can use this drive.
