Odd drive lettering in Task Manager

There was post recently about someones drive showing up in Task Manager. As I was looking at the issue on my main system I noticed an issue myself. What I am seeing is the Sata HDD, under Task Manager, is showing 2 drive letters yet only one partition exists. I have been able to determine I am seeing this on other Win11 systems, but not all. Let me post a screen shot:





That is a screenshot of Task Manager, Disk Management and This PC showing the drives. Under TM the HDD(Disk 0) is showing (G: D:) The boot drive is C:, the Sata HDD is D: and a secondary NVME drive is E:. My Google drive is also showing G: so that is confusing.

I have a spare system, Z790, showing similar. That one boots to an NVMe C: drive, the D: drive is a Sata HDD(D:) and 3 more NVMe drives on board. On that one the Sata HDD is also showing D: G: however one of the NVMe drives drive letter is H: but the Google drive on that one is G:.

I've been scratching my head trying to figure out why I am seeing the drive lettering this way but it doesn't do it on every Win11 system I have running. I am thinking(possibly) this is only appearing on the Win11 systems I performed an In-Place upgrade to 24H2 and the other ones not showing this were systems I clean installed 24H2. All of my Win11 systems are booting to M.2 drives and typically have a Sata HDD for storage.

My main system is an Asus X570, Ryzen 5900X, R6950XT video, 64 GB memory. Primary boot drive 1 TB WD SN850X, secondary M.2 slot is 2 TB WD SN850X, Sata HDD is a Toshiba 8 GB.

Task Manager shows each physical disk as a separate item. In the brackets it lists all drive letters that refer to each of the drives, usually that would be any partitions on that drive that have letters assigned. Your Google drive G: is a virtual drive, but the physical location of your offline files is on your D: drive. The default location would have been C:\users\<username>\Appdata\Local\Google\DriveFS but it looks like you have moved it to the D: drive. As such, G: is a drive letter associated with the drive containing your D: partition, so it makes sense to show this as Disk 0 (G: D:).

So this really is a Google drive thing? In checking it is using the Default C:\Users\<username>\Appdata\Local\Google\DriveFS under "Local cached files directory" ??? Same with the Z790 system mentioned.
