{Forum} Seagate Hard Drive Donor Matching Guide

The following guide will help you to find the most compatible donor hard drive to fix or repair a damaged Seagate hard drive in order to recover the data. This will not guarantee 100% success but will improve your chances greatly of finding the most compatible donor hard drive.

This Seagate donor matching guide is split into two sections. Please first determine by looking at the hard drive sticker which series of Seagate you have. Your hard drive label may look different to the one shown due to revisions and different models of Seagate hard drives. But the main matching criteria will always be present on all hard drive stickers.

We have color coded each matching aspect into 3 category’s:

The following matching criteria applies to both laptop 2.5″ size drives and desktop 3.5″ drives.
