Hi guys ! after much success with simple USB W.Digital My Books for a number of years to store my extensive iTunes library, photos, etc having read so many wonderful things about OWC/NewerTech Guardian Maximus Quad interface Raid box, i decided to take the plunge, ordered one & installed 2 Western Digital Caviar Green 3TB bare drives in it using CarbonCopyCloner i copied the content to these & started using it. right from the start i noticed my late 2009 27'' iMac i7, with 16GB RAM, constantly ''freezing'' when connected via FW800 yet when i tried it via USB it was all good !?.. i have 4 more W.Digital My Book drives, an H.P C6180 all in one printer, a Cambridge Audio DacMagic, an APC UPS connected to my computer via USB through a pair of Logitech Premium powered USB hubs + my HD plasma TV via mini-DisplayPort/HDMI adapter & a Wacom Cintiq 21UX also via an adapter thinking it might be caused by some weird incompatibility between any one of these components or so, i unplugged EVERYTHING from my iMac, made sure EVERY power supply for the above were ALL in working order ( they are.. ) checked & double checked ALL the cables ( even got a couple of new ones just in case..) checked the USB hubs + their power supplies, you name it - EVERYTHING IS O.K. ! tried plugging in one component at a time - everything worked fine ! however each & every time i plugged in the Guardian Max via FW800 it happened, time & again....regardless if plugged by itself or in combination with any other component funnily enough the Guardian Max connected via USB gave no problems whatsoever !? after a little ''Googling'' i could see i'm NOT alone with this sort of problem among Mac users & that it happens with all sorts of drive makes .as long as FW800 is being used !? has anyone come across this quirky behavior or has any idea what might be the solution for this ? i mean, to stream the music, USB is plenty fast but it's still frustrating to have intentionally bought a FW800 capable box & not be able to use its advantages many thanks !
