| Exact model | Seagate ST-296N |
| Product generation | 40 MB-class 5.25-inch half-height SCSI hard disk, 1980s |
| Form factor | 5.25-inch half-height class; this classification is not a dimensional drawing. |
| Interface | N suffix denotes the SCSI model; the OEM manual specifies its SCSI host and configuration requirements. |
| Capacity, performance, sector / recording details | The ST-296N is the 40 MB model in Seagate’s ST-225N/ST-251N/ST-296N SCSI family. Exact geometry, sector addressing and formatted capacity are controller/manual dependent; verify the ST-296N table, not another family capacity. |
| Compatibility | Requires a compatible SCSI host adapter, correct SCSI ID and bus termination at the physical ends. An MFM ST-296-family lookalike is not the same interface. |
Handling, service & preservation
- Record SCSI ID, termination, connector/cable style, and board state before removal. Legacy SCSI controllers may have specific termination-power needs; verify the adapter manual before powering.
- Photograph the full label, board marks, connectors, jumpers/carrier, and date/firmware codes before service; retain the exact model suffix with collection metadata.
- Never open a hard drive outside a qualified clean environment. Stop repeated power-on attempts if the unit clicks, drops offline, or develops read errors.
- Preserve source data by making independent copies and validating checksums; SMART/self-tests cannot guarantee reliability. Distinguish measured condition from manufacturer specifications.
Model-specific source
- Seagate ST-225N OEM Manual (SCSI family manual; archival scan)Original Seagate SCSI OEM manual covers the ST-225N family and model-specific variants; consult the ST-296N portion for its own specifications.
For variants with family manuals, use the model-specific table and document revision that matches the drive label.
