Package included:1Pcs Review: No issues at all - Works perfect with an old 486 SX machine. No issues with this converter but look into the potential limitations of your machine.

The CF card I put in was recognized by the motherboard and I was able to format it.

In these occasions, the power supply needs to be turned on/off frequently. Traditional mechanical hard drives are easily damaged. CF is a kind of electronic hard disk, which is completely different from mechanical hard disk in principle, and it is not easy to be damaged in these occasions - Portable instruments that use embedded X86 or RISC cores usually have IDE interfaces. If the CF card cannot be directly connected to these instruments, you can use this adapter to complete the transfer - Personal computers (PCs): These computers are usually x86 kernels, which are the main platforms used by the card. Some digital cameras have a CF card interface. You can access your picture data on a desktop computer through this card - Industrial PCs use this card and CF card together to store embedded operating systems such as embedded LINUX or WIN CE - Support CF-I and CF-II two types of cards: also support IBM micro hard disk with CF-II interface. 5.0V or 3.3V power supply: select the appropriate power supply voltage according to your CF card ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097XS4SXP | | Best Sellers Rank | #51 in Computer Memory Card Adapters | | Brand | SaiDian | | Color | White | | Compatible Devices | Cameras | | Connector Type | IDE | | Customer Reviews | 4.4 out of 5 stars 62 Reviews | | Finish | Matte | | Finish Type | Matte | | Input Voltage | 5 volts | | Manufacturer | SaiDian | | Mfr Part Number | SD550 | | Model Number | SD550 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | Type A - 2 pin (North American) | | Specific Uses For Product | Camera, PC | | UPC | 779675961991 | | Unit Count | 1 Count | ## Product Details - **Brand:** SaiDian - **Color:** White - **Compatible Devices:** Cameras - **Connector Type:** IDE - **Specific Uses For Product:** Camera, PC ## Images ![SaiDian 1Pcs 40Pin CF to IDE Adapter Compact Flash Card to 3.5 Converter - Image 1](https://m.media-amazon.com/images/I/41Z2Yhj2udS.jpg) ![SaiDian 1Pcs 40Pin CF to IDE Adapter Compact Flash Card to 3.5 Converter - Image 2](https://m.media-amazon.com/images/I/61dHboYdXRS.jpg) ![SaiDian 1Pcs 40Pin CF to IDE Adapter Compact Flash Card to 3.5 Converter - Image 3](https://m.media-amazon.com/images/I/51fSXncFh0S.jpg) ![SaiDian 1Pcs 40Pin CF to IDE Adapter Compact Flash Card to 3.5 Converter - Image 4](https://m.media-amazon.com/images/I/51NZK+mIbIS.jpg) ![SaiDian 1Pcs 40Pin CF to IDE Adapter Compact Flash Card to 3.5 Converter - Image 5](https://m.media-amazon.com/images/I/51wn2ZGV7BS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ No issues at all *by D***S on August 5, 2026* Works perfect with an old 486 SX machine.
