My hard drive finally went kaput on my mac, and it is in the mac hospital getting a replacement. I knew this was going to happen soon, so earlier this year I purchased an external to put everything on. However, I formatted it for Mac use only (I know that was stupid). At the apple store the genius recommended MacDrive. I came home installed it, worked beautifully, however, my internet browsers all pooped. Nothing will connect. I reset my router, restarted everything still no joy. So, I decide I'll go to my Windows XP machine and do it, maybe that will be better. Wrong, it was the only computer left working in the house and as soon as I installed MacDrive, the browsers stopped connecting again. So, I uninstalled it off my Windows8 laptop and my browsers started connecting again. I would be leary of it.
