Pulled from a 1999 Maxtor 4.3 GB IDE hard drive (Model 90422D2), this original controller board is ideal for professionals specializing in data recovery or forensic reconstruction of late-90s IBM-branded Maxtor units.

Condition: Untested, sold as-is for recovery or parts

Compatibility: IBM P/N 36L8631 / FRU 12J3143 / Maxtor 90422D2

Details: Clean board, no burned traces or missing components; includes four matching hex screws

Background: Cataloged under internal Experiment 55A forward for tracking; previously stored in antistatic protection

Ideal Use: Head-swap calibration, firmware donor board, or lab matching to recover data from drives that “click then nothing”

The value here isn’t scrap — it’s precision matching. Boards from this era are increasingly rare, and authentic, unmodified PCBs are critical for recovery success.
