“I have a hard drive that works all the time. But when I connect it to another computer with a different operating system, it shows up as a GPT protective partition (Healthy) with no drive letter. I can’t read it or make other operations on it. What should I do to solve this problem? All suggestions are appreciated in advance!”
What is GPT protective partition?
First of all, you should understand what a GPT protective partition is. As you know, comparing with MBR (Master Boot Record), GPT (GUID Partition Table) provides a more flexible disk partitioning mechanism and is widely used in most Windows operating systems except Windows 32-bit operating systems. For example, 32-bit Windows XP and Windows Server 2003 give no support to GPT disk. That is to say, when users connect a GPT disk to a 32-bit Windows XP or 32-bit Windows Server 2003 computer, this disk will not be shown in Windows Explorer. At this time, the GPT disk shows up in Windows Disk Management as Healthy (GPT Protective Partition) with no drive letter. And you cannot right click it to assign a letter. As a result, the data on the GPT Protective Partition becomes inaccessible.
