HELP! My hard drives keeps ejecting... - My HDs are LaCie and G-tech since these are good hard drives and they are both ejecting I dont think they are the problem - It keeps ejecting in both of my old iMac and new iMac (3 weeks old) so I think its not the computer. - Ive tried it in both mavericks and yosemite and still same - both connected via USB What could be the reason for this? You think this is a power failure? Or is it the files inside the hard drives making this issue? Note: They are main and time machine drives so they both have same files. Hope someone can help. thanks!
