I always had success with the Seagate FreeAgent Go drives on the Wii. Now Seagate has introduced a new line of drives called GoFlex. They have a proprietary connector that allows you to switch interfaces (USB 2.0, USB 3.0, FireWire, eSATA, etc.) by buying additional adapters. I bought the one that ships with the USB 3.0 adapter since it's supposed to be backwards compatible and happened to be on sale. Out of the box, the drive will be recognized by all loaders. However, if you quit a game, go back to the Wii menu, and re-run the loader, the drive will fail to be initialized. I tried this with USB Loader GX and Configurable Loader. (USB Loader GX will be able to read the games on the drive, but will fail loading them. However, I have not attempted to downgrade any CIOS versions. YMMV) The solution to the problem of the drive only working once is to turn off the sleep mode. After doing so, I was able to quit games, rerun Configurable Loader, and run another game. You need to install the "Seagate Dashboard," so be sure to back up those files before you reformat the drive.
