Overview
The Maxtor XT-1085 is a vintage 5.25-inch full-height hard drive designed for legacy computing and industrial systems. With an 85MB formatted capacity, SCSI 50PIN interface, and 3600 RPM spindle speed, this drive serves as a critical replacement component for maintaining older computer systems, CNC machines, and industrial automation equipment that depend on original-specification storage media.
Key Features
- 85MB Storage Capacity — Formatted 85MB capacity suitable for legacy data storage and system boot drives.
- SCSI 50PIN Interface — Standard SCSI protocol connectivity for seamless integration with vintage host adapters and controllers.
- 3600 RPM Spindle Speed — Reliable rotational velocity delivering consistent seek times (27 ms average track-to-track, 4 ms per-track).
- 26.5W Power Consumption — Low-power design compatible with older PSU architectures.
- Dual Supply Voltage — Operates on standard 5V and 12V rails common in vintage computer enclosures.
Technical Specifications
The drive meets legacy system requirements with a data transfer rate of 0.625 MB/s internal and external, sector size of 512 bytes, and MFM recording method on selected variants. Operating temperature range is 10–45°C, with non-operating range of −40 to 60°C. MTBF is rated at 30,000 hours, and the drive includes a 30-bit ECC implementation.
Typical Applications
- CNC machine tool retrofits and legacy equipment restoration.
- Industrial automation systems requiring original OEM storage media.
- Vintage computer workstation and server maintenance.
- Legacy computer museum exhibits and archival preservation.
- Industrial test equipment and measurement system support.
