I got one of the seagate freeagent goflex 500g usb3.0 drives from walmart (STAA500105 and PN:9ZFAN6-570). I used the software to disable the spindown feature and then used wii backup manager to format the drive. I installed many games and they worked flawlessly. Later on I copied my vba roms to the drive (using the standard windows 7 file manager 64bit) and went to plug it in and not recognized anywhere, reformatted it (several times, using windows, using wii backup manager, some gui partioner, and easus partition manager) and each time the device just does not show up at all on the wii. I tried plugging it in and then powering the wii, powering the wii first, then plugging it in, plugging it in and out at the usbloader screen, tried it in all my emulators, etc. I plug in my 16gb usb stick and it shows up fine, games run fine. I plan on returning it and getting one of the Western Digital 500GB My Passport Essential USB 2.0/3.0 External Portable Hard Drive Model#: WDBACY5000ABKSN tomorrow. Wonder if anybody has any tips for the goflex or should I just go with the WD?
