I have two HDD from from two separate desktops that I want to transfer data to my Dell 5558 laptop. One HDD is a SATA/IDE where the mobo failed and the other is a second IDE drive for data only where the OS HDD failed. I have a Coolmax CD-350-COMBO SATA/IDE Data Transfer Cable Adapter CD-350-COMBO USB 2.0, with the power supply. Amazon.com: Coolmax CD-350-COMBO SATA/IDE Data Transfer Cable Adapter CD-350-COMBO MFG#(15438): Computers & AccessoriesMy device has a both a data USB 2.0 and a power USB for additional power above 500 mA when required by some HDD. The device also has a power supply with a 4 pin connector. I have read some reviews there are some problems with this device, so I would like to get some input on the best way to use it or choose another device.
