My 3TB WD30EZRX has been working fine for the last few weeks I've owned it. I've been using it to backup files from older, smaller disks so I can consolidate and not have to keep 6 HDDs in my tower anymore. Yesterday I used PerfectDisk 11 Pro to defrag all my drives (like I do every month or two) and this was the first time the 3TB drive had been defragged. Upon rebooting from that overnight task, I discovered that my 3TB HDD is now listed as RAW instead of NTFS in Windows 7 Disk Management. It still has a drive letter assigned to it, but trying to open it gets the error: "You need to format the disk in drive K: before you can use it. [Format Disk] [Cancel]" -- when I hit "cancel" I get this popup: "K:\ is not accessible. The volume does not contain a recognized file system..." So I run EASEUS Partition Recovery 5.0.1 only to discover that it doesn't work with GPT drives, only MBR. It says that I need to use EASEUS Data Recovery Wizard ($70) instead to move the data off that drive to another and reformat. But I believe that all my data is right there and can be restored by whatever the GPT equivalent is to fixing an MBR. Is there an application that fixes the GPT similar to the functionality of FixMBR?
