I’ve been trying to synchronize two 1TB external hard drives. I found out yesterday that Mac OS X can’t natively mount NTFS for writing. I brought them home to use the home (windows) laptop to do the job. It was going to take 20 hours, so I let it run overnight. This morning, I wake up and checked on it, to be cheerfully informed by windows that it installed a new update, and rebooted. Wasn’t it a good boy?? Wasn’t it helpful??
