This looks like a small partition on your hard drive. In my experience, updating or upgrading another OS on the same computer can cause these small partitions to be shown or hidden to Linux. (eg, Windows 10 > Windows 11)
If you're curious, you can find out if it is physically located on your internal hard drive by running a 'mount | grep' command, then looking at the output. Here's how:
- Open a Terminal
- In the terminal, type this command:
mount | grep Wolumin
This should return something like this:
douglask@doug-GxxxJM:~$ mount | grep Data
/dev/sdb4 on /media/doug/Data type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)
I don't know how much you know, so I may be going too basic here. If I am, I apologize!
The part of the above output we're interested in is the /dev/sdb4 right at the start of the line. That refers to a special folder on the file system called /dev which holds special device files. More info here.
Devices beginning with sd are normally hard drives. sda is the first hard drive and typically holds your operating system(s), sdb is the second one and so on. If it's an sda, sdb, etc device, it's a physical drive. The number is the partition number.
It's good to know how many drives are inside your computer as usb drives will show up as being beyond the internal drives. For example, my computer has sda and sdb inside it. If I attach an external USB drive, it appears as sdc.
If it's something else, that first portion of the mount line may give you a clue regarding the type of device, and what might be some good search terms.
