mkdir falsely complains no such directory on mounted volumne

I am attempting to create a directory on mounted volume M2 but mkdir is failing. I suspect this is a permissions issue, but the listed file permissions are all rwx. I have tried chown -R me M2/ but that did not solve the issue. Possibly relevant is that I am dual booting and though there are no system or user files on this drive, I did write most or all of the existing data to this drive from windows. OS version 20.04. Output is as follows:

(base) me@me-ub:/M2$ ls -la
total 3993
drwxrwxrwx  1 root root   28672 Oct 24 12:50  .
drwxr-xr-x 25 root root    4096 Feb 10  2021  ..
drwxrwxrwx  1 root root       0 Jan 16  2022 '$RECYCLE.BIN'
drwxrwxrwx  1 root root   16384 Oct 18  2021  stu
drwxrwxrwx  1 root root   12288 Oct  2  2021  pucks
drwxrwxrwx  1 root root 1466368 Oct 26  2021  Camera
...

It appears that the files on this drive are almost all read-only, however I was able to create a new directory one level down in one of the existing dirs. What should I do?

Is the drive really mounted, and is it read-write-mounted? (do `mount | grep M2` to find out.)

@Jos output reads `/dev/nvme0n1p2 on /M2 type fuseblk (rw, ...`, I assume rw is read-write?

All of the directories in `/M2` are writeable (by an ordinary user), but the directory `/M2` itself is probably not writable, which you can verify by doing `ls -la /`, or looking at the top line with the `.` directory. From the `drwxr-xr-x` permissions, you would need to be the owner (`root`) of `/M2`. That explains why you can create a directory one level down, but not in `/M2`.

The issue was caused by dual booting with fast startup enabled on windows. Disabling fast startup solved the problem.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
