Hey all, last night I noticed one of my existing 4TB GPT disks went missing. I checked Disk Manager this morning and noticed it was changed from a GPT Data Partition to an GPT EFI System Partition.
I have no idea HOW it changed partition types over. If I use Minitool Partition WIzard, I can still see the files on the disk, but can't access them. I can't restore the partition either through Partition Wizard.
I found a guide online of using GPT fdisk to change it but I am concerned it will overwrite all the existing data (currently have over 3TB of data on the disk). This is what it stated:
Two questions:
1. Is there any other way to convert that partition back to something usable without data loss?
2. Any idea how this happened? The drive is in an eSATA enclosure and I did swap controller cards last night but this is the only disk affected.
3. Is the guide I found going to work and not delete data?

For the benefit of others, use gdisk 0: (substitute the number of the affected drive). Type p to print the list of partitions. The EFI System Partition will have a type of EF00. Enter t to change the type, select the number of the partition, and then type the code for the standard Windows partition, which is 0700. w will then write the changes, and after a reboot you should be back to normal.
