It came in pre formatted as NTFS and I had macfuse and NTFS-3g installed from before. I copied some 200GB (2TB WD HD) into the hard drive and then while copying stuff, Finder just hung and I had to restart my computer. After then when I restarted my external hard drive the hard drive would load but those 200 GB disappeared!! I mounted the hard drive on windows to safely eject it BUT on windows its disappeared too. IDK what to do, I'm screwed if I can't get that 200GB back... What should I do??
