I came home from work tonight and my VirtualBox hosted Windows 10 image showed a bluescreen so I attempted to restart the VM. I let it sit for 30 minutes and it didn't respond so I tried to kill the Virtualbox application and after waiting another approximately 30 minutes I did a hard reset of the computer. When it came back up the Windows 10 loading "spin" animation was onscreen forever then a chkdsk warning came up. After chkdsk failed I get into the Windows 10 Explorer and I see the HD listed but no drive letter is shown. I ran testdisk and it sees the partition "Media" which was my G: Drive and I've tried to write the partition and go into advanced and try the rebuild option and still no luck - get the "write error".
I have rebooted several times and there was one time where the disk actually appeared like normal after the usual slow boot and lack of drive letter and then all of a sudden it appeared and worked normally. I thought perhaps it recovered on its own and on the next reboot it is dead again. If I try to use chkdsk from an elevated command prompt it runs for a bit then says an unspecified error occurred.
I am hopeful I can recover the files on the drive as the Media drive has all my music on it in addition to my Virtualbox environment. I have included the log file for review as well - it has a ton of errors

Thanks!
