Time Machine Slow on Lion 10.7.5
Time machine keeps saying it's preparing and it's going on for ages, when it finally gets going there's only a couple of Gig to do but it's just taking forever. The drive is connected via USB and was OK till I went from OS 10.7.4 to 10.7.5.
iMac, Mac OS X (10.7.5), 3.4Ghz (16GB Ram) Intel Core i7
