I just bought a Western Digital 1TB hard drive. I went to transfer all the files from my old hard drive to the new one on my MacBook Pro and it doesn't let me. What am I doing wrong.
Hey I'm needing to revive this topic. My hubby bought me a 2tb WD hard drive but it's the 'My passport for Mac' well what I use my hard drive for I need my PS3 to be able to read files on it. So I figure I need to reformat but in my options in the screen above MS-DOS (FAT) is not an option. Only the Mac OS options and ExFat.regarding the "cannot dismount volumes" thing - have you tried restarting? Your computer may still be trying to use files on that drive for some reason, and restarting ought to take care of that.
To format it to be compatible with windows and Mac, open Disk Utility, select the hard drive in the left column, select the "Erase" tab, choose "MS-DOS (FAT)" next to "Format", then click "Erase". The biggest drawback with using FAT32 is that it cannot hold files larger than 4GB (usually videos). If that isn't an issue for you, it should otherwise work pretty well.
So I just exchanged the hard drive for one not formatted for Mac. My MacBook sees the drive but the drive says "read only". How do I fix that?In my screenshot above, click on the "partition" tab at the top. In the drop-down menu at the left of that window, choose the partition scheme you want (sounds like you just want one, but you can pick whatever). Then the important part is to click the "options..." button underneath the partition layout. It's probably on "Apple Partition Map" now, which isn't compatible with FAT. Choose "GUID Partition Table", then "apply" and then you should be able to format to FAT like you want.
