I used this adapter to replace an old computer's hard drive with an SD card. Now I can transfer files much easier. A few tips in case it helps anyone: Be careful with exposed pins under the board. I trimmed the pins with wire cutters and taped the circuit board to the plastic wrap with double sided tape to make sure they didn't short out. The computer did not boot from the SD card after installing DOS. Running fdisk /mbr solved this problem.
