I have recently connected a 2nd internal hard drive to my mac; this has alot of my work on it. When i look in disk utility it says it isnt mounted. How do i reformat the drive to Journaled HFS+ and keep the data i have on it?
thank you, slex.
You don't. Formatting involves a complete change to the low-level data structures that tell the file system where one file begins and another ends. NTFS and HFS+ have completely different ways of doing this - you can't switch between the two without losing everything. What you will need to do is copy the data off (perhaps by using NTFS-3G, though I could have sworn Mac OS X had read-only NTFS drivers - can you use Disk Utility's mount button?), format the hard drive, then copy the data back on.
