It was working fine and suddenly, after WD’s suggested upgrade, my MacBook Pro Laptop with Snow Leopard will no longer recognize the drive. The drive is not password protected and I use Time Machine on the Mac. Has anyone else had this problem? My complete back-up is on the Passport so I am not big on reformatting it. I bought it to protect myself and now it seems like it is more of the problem. What gives?
I am having the exact same problem! I just upgraded to the newest iMac G5 with Snow Leopard and it is not recognizing my WD My Book (1TB) . I tried both the FireWire cable and the USB. I do not want to reformat either as I transferred data there from my old Mac. I do not want to overwrite, just add new back-up data. Please WD, help. Or any other enlightented Mac Snow Leopard user. Thanks.
