During a re install of Windows 8.1, I was having trouble setting up a RAID.  In the Device manager, I accidentally converted my "File" drive to GPT.  Now, all my files are lost.  Is there a way to convert the drive back?  (Currently, the drive doesn't even have a drive letter.)

Hi Tony,

Before doing this kind of operation, you have to backup all your data and delete all partitions and volumes.

Now it's recommend you ask professional data recovery center to save your data before roll back as Nicolas BONNET suggested.

If the data is not important for you and you don't want them back, go ahead as
