[ IDENTIFIED HDD // MODEL-SPECIFIC RECORD ]
Seagate Cheetah ST39103LW
9.1 GB; 3.5-inch; Wide Ultra SCSI. Open model identification, compatibility, preservation, and source notes. This record describes the named model only; similar family names or suffixes are not interchangeable.
IDENTIFICATION: Read the complete model and suffix from the drive label, record firmware and serial information, and match them to the cited manual. Interface or capacity alone does not establish compatibility.

Compatibility and data-recovery safety
- Before use, check the full model/suffix, connector and signaling, host-controller support, power, mounting, firmware behavior, and sector presentation. Physical connector fit is not proof of electrical compatibility.
- Use the matching controller and bus setup: PATA needs correct cabling/jumper configuration; SCSI needs a compatible adapter, unique ID and termination; MFM/RLL needs an appropriate controller; SAS needs a SAS-capable host (not a SATA-only controller). Follow the exact manual.
- If data matters, avoid writes, formatting, filesystem repairs, repeated power cycles, and stress tests. If it clicks, repeatedly spins up, disconnects, or reports read errors, power it down and do not open it. Consult a qualified recovery specialist before DIY procedures; where appropriate, image the media read-only before analysis.
- Preserve the original label, jumpers, cables, adapter, firmware/host details, and acquisition notes. Keep verified checksums and independent copies; an aging HDD should never be the sole copy.
- SMR models can have different sustained-write and rebuild behavior; verify the exact recording technology and workload suitability before RAID or write-heavy use.
