Seagate Momentus 5400.3 ST980815A
80 GB, 2.5-inch mobile PATA hard drive. This record is for the complete ST980815A model code; a similar SATA suffix is not interchangeable.

Compatibility, noise, shock and reliability
- Requires a PATA-capable host or bridge, correct master/slave or cable-select setup, a compatible 44-pin connector and 5 V supply. A SATA-only port will not operate it.
- Manufacturer documentation lists about 2.3 bel idle noise (sound power) and up to 3.0 bel during seek, with operating shock rated at 350 G (2 ms) and non-operating shock at 900 G (1 ms); these are defined test limits, not handling targets.
- The listed 600,000 load/unload-cycle rating is a design specification, not a remaining-life estimate. Clicking, repeated spin-up or read errors warrant stopping writes and unnecessary power cycles.
- Legacy BIOS capacity limits and adapter translation can affect detection. Confirm the host's reported capacity and sector size before cloning or partitioning.
