2GB 40-Pin IDE SSD CF Card Adapter for Legacy 3.5-Inch PATA Hard Drives

This 2GB solid-state storage kit is designed to replace many aging 3.5-inch IDE/PATA hard drives used in vintage computers, industrial systems, and embedded equipment. The CompactFlash card operates through the included 40-pin desktop IDE adapter, providing silent storage with no moving parts.

Technical Specifications

• Storage Capacity: 2GB
• Storage Type: CompactFlash solid-state memory
• Host Interface: 40-pin desktop IDE/PATA
• Operating Mode: CompactFlash True IDE mode
• IDE Configuration: Master or Slave selectable by jumper
• Power Connection: External four-pin peripheral-power connection
• Drive Type Presented to Host: ATA storage device
• Moving Parts: None
• Hot-Swap Support: No
• Physical Format: CompactFlash card with exposed adapter board
• Intended Application: Replacement for compatible legacy 3.5-inch IDE/PATA hard drives

Exact reported geometry, LBA sector count, transfer modes, fixed/removable status, power consumption, and environmental ratings depend on the supplied CompactFlash card.

☑️ Package Contents

• 1 x 2GB CompactFlash storage card
• 1 x 40-pin desktop IDE/PATA adapter board
• 1 x Four-pin peripheral-power adapter lead
• 1 x Master/Slave selection jumper installed on the adapter

A 40-pin IDE ribbon cable, mounting bracket, drive rails, screws, and operating-system software are not included.

⚠️ Important Compatibility Information

• Designed for standard 40-pin desktop IDE/PATA interfaces.
• Not directly compatible with 44-pin laptop IDE, SATA, SCSI, or SAS connections.
• The host BIOS or controller must support a 2GB ATA storage device.
• Very old systems with a 528MB BIOS addressing limit may not recognize the card correctly or may use only part of its capacity.
• Master or Slave jumper selection must match the original drive configuration and IDE cable arrangement.
• Some industrial and embedded systems require a specific drive geometry, sector count, or fixed-disk identification.
• For sector-by-sector cloning, the destination card must contain at least as many addressable sectors as the original drive. Matching the rounded capacity printed on the label is not sufficient.
• This adapter is not a fully enclosed 3.5-inch drive. Secure mounting may require a customer-supplied bracket, tray, or insulated mounting method.
• Turn off and disconnect the equipment before installing, removing, or reconfiguring the adapter.
