A RAW partition means the partition table is corrupted. But because you have one good partition on the drive, there is a good chance you can access and recover the data on G. Edit: I am assuming partitions E and G are on the external drive, correct?
I would start by using Partition find and mount. You may have to do a thorough scan. If it finds the RAW partition, you can mount it as a drive letter and copy the data. After copying make sure you open some of the files to see if they are corrupted or not. Here is a guide. Don't bother with the compressing files and folders section. Just make sure you have enough space on the recovery drive.
If you cannot find the partition using Partition Find and Mount:
Download Testdisk for Windows. Unzip to your desktop in a folder. Here is a guide on it's use. Because you have an external drive, you can use the Windows version and not Parted Magic as shown in the guide. But, It's possible by using PartedMagic, you could access G directly without using Testdisk as it's linux based and may be able to mount the drive. Here is the last free version of Parted Magic. If Parted Magic cannot mount the drive and find the partition, then use the Windows version of Testdisk.
As the guide says, do not write any data back to the drive until you can see your files listed. I would recommend you copy all files before you attempt to write a new partiton table. The default location for copying data is the folder you unzipped Testdisk to.
