Seagate ST3750330NS SATA 3.5 PCB - 9CA156-883 SN06 100468979 L

Product is the hard drive circuit board / logic board only for Seagate ST3750330NS (9CA156-883, SN06, 100468979 L). No hard drive or additional components are included. Because we stock many of these PCBs, the exact board you receive may differ slightly from the photo. This PCB is intended for use in hard drive repair or data recovery applications. Before purchasing, verify compatibility by consulting our Donor Matching Guide and follow the Hard Drive Diagnostics Guide to confirm a PCB replacement will resolve your issue. Most Seagate boards store unique calibration and configuration in a ROM ("memory") chip; that ROM data is required for the drive to function correctly. The ROM chip or its contents must be transferred to the replacement board; if the chip can be physically moved, a local computer technician can perform the swap. For customers with orders of $60 or more we include free adaptation service, which covers either transplanting the ROM chip onto the new PCB or reprogramming the replacement board with the correct ROM data. If you plan to do the work yourself, review our PCB Replacement Guide. If a simple board swap is insufficient, we also provide a dedicated PCB Replacement Service — see the Adaptation Service page for full details.
