Can I use one external hard drive for two different operating systems, and the OS’s Windows 7 and Mac, or Windows XP and Mac? Well, there are a couple of ways to accomplish this. Here I will introduce two circumstances: sharing external hard drive for two computers on two different operating systems, share hard drive on two different operating systems on one computer.
How to share hard drive for two computers on Mac and Windows
Have you ever encountered such problem as me: I bought one external hard drive, and connect it to my sister’s macbook pro, the hard drive can be recognized, but it cannot be written anything after opened it. Then I go to the shop where I bought this drive, the repairman formatted the hard drive under Windows OS, it can be written and read on Mac OS computer, but after I go home, i connect the hard drive to my Windows computer, the drive cannot be recognized. What should I do? Well, I search from the internet, and found one solution.
First, connect the external hard drive to Mac OS computer, backup the important data, then go to Disk Utility, click the erase the disk, then format the hard drive as ExFAX, waiting for the format processing.
Second, prepare the hard drive program (different hard drives have different programs, please prepare according to the model of your hard drive), and Windows updating program (WindowsXP-KB955704-x86-CHS.exe). Then connect the hard drive to Windows OS computer, a window pop up to prompt find new hardware, then find hard drive program to install. If there is no drive under the Windows at this time or the hard drive cannot be recognized, please install the Windows updating program that I mentioned above. Then you will see the content of your hard drive, and the hard drive can be written and read. Now you can transfer movies, songs, photos, documents, etc. between different systems such as Windows 7 and Mac or Windows XP and Mac.
Share hard drive on different systems on one computer
Is there universal partition format can be used on Mac and windows simultaneously? I have an external hard drive, and I have installed Mac OS on my Windows 7 computer, and want to use hard drive on these two operating systems, but I find the NTFS format files under Windows OS cannot be read or written on Mac OS, the files which saved as Mac partition format cannot be read and written under Windows OS. Is there some way to achieve this purpose that can use external hard drive on different systems? Of course, just put the partition of “Mac OS Extended (Journaling)” as the final partition of hard drive, the problem will be solved.
As the installation file of Mac OS is smaller than 8GB, we can do partitions for external hard drive under Mac OS, format the first several partitions as MS DOS mode, and finally format the last partition as Mac format.
So you can access the hard drive except this 8GB partition, and the hard drive can not only be used as startup disk to install Mac, but also it can be used as data…
