Mac Formatted Drive on Windows

If the drive recovered was from a Macintosh computer the target drive was most likely be initialized for a Mac (HFS+). If you are now on a Windows computer or just need to look at the data on a Windows computer you will need to use a program that will allow Windows to view the HFS+ file system. One program that can be used is called Paragon HFS+.

If you have a need to be able to read from a Mac formatted drive on Windows or you want to share a drive between Mac and Windows then this is a worthwhile purchase. If you only need to connect the drive for a short time to get the files off the drive then the trial period will give you 10 days.
