i have uk pal wii soft mod fw ver4 with a iomega 3.5" 1tb drive with external psu brick , with 101 games on 500gb wbfs main partition + 500gb ntfs second partition. with usb loader gx ver533 in hbc and cios ver10. just realised ver 541 boot dol out . so i will test that tonight but in mean time my wii always intermittantly recognise the 1tb hdd and it will only reocgnise it in the usb port paralell to the dvd slot . - inside is a hitatchi 1tb sata (others have reported to have wd drives inside , so its hit and miss ) . if i turn wii on , and leave usb plug in . then turn on 1tb after getting to channels menu . then loading usb loader gx forwarder channel . it is then most likely to recognise it . otherwise sometimes it will stay on the white back ground / none of the footer (clcok / disk size/ buttons) stuff load and it will just freeze but cursor moves or cursors missing . or it will come up with wait 30 secs use ios249/222 but it will never find it . so i have to exit back to channel menu / or reboot wii if its frozen . then switch off/on 1tb drive then reload usbloader gx . ( at this point i dont have to resseat usb cable at all ) so you can imagine when i exit the game, and wii restarts to main menu - it then looses the hdd . mostly i know when usbloader gx will recognise the 1tb drive as i can physically hear it click and spin up then usbloadergx is most likely to reocgnise it . on the other hand , i have a 160g seagate ide , which recognises perfectly on time in any usb slot . but its obviously too small to hold all my 100+ games preferbly . so i need my 1tb drive so it must be compatibility issue so that leads me to my next qs i am trying to find out what is root cause be it driver/ ios for recognising hdds . is updating cios or usbloader gx more likely to give wider hdd compatibility . the hdd manufactur number is hitachi hdt721010sla360 if that helps . if not , how can i edit usbloader gx to include compatibility for the 1tb hitachi sata hdd . and i dont think it is because i have 101 games , so its trying to cache it . because this problem was apparent when i only had 27 games installed. i hope i havent bored you , but i wanted to give as much detail to help solve my problem . thx .
