  • Compatible with ST380811AS and ST3160815AS drives
  • Replaces PCB part numbers 100428473 REV C and REV B
  • Also fits board revisions 100439890 100441714 100457858
  • BIOS swap required for drive recognition
  • Professional soldering tools needed for installation

Compatible Seagate models

This replacement PCB matches Seagate drives ST380811AS and ST3160815AS using board numbers 100428473 REV C, 100428473 REV B, 100439890, 100457858 and 100441714. It is intended for technicians and data-recovery specialists who need an exact logic-board swap.

Soldering and BIOS transfer required

The board arrives as a bare logic unit without the original drive's BIOS chip. Each hard disk pairs uniquely with its own BIOS, so the chip must be moved from the failed board to this one using soldering equipment. Without that transfer the system will not recognise the drive.

No tools or firmware included

The package contains only the replacement PCB; no soldering iron, hot-air station, BIOS programmer or flashing software is supplied. Users without microsoldering experience should engage a local electronics repair shop to perform the chip migration and any necessary firmware adaptation.
