Fortunately I just started Windows 7 for another thread here, so I
gave it a try myself:
$ uname -a
CYGWIN_NT-6.1 vmbert764 3.1.4(0.340/5/3) 2020-02-19 08:49 x86_64 Cygwin
$ id -G | grep -Eq '\<544\>' && echo elevated || echo non-elevated
non-elevated
$ cat /proc/partitions
major minor #blocks name win-mounts
8 0 54525952 sda
8 1 102400 sda1
8 2 54420480 sda2 C:\

This appears to be a local phenomenon only, either some permission
problem, or some BLODA, a life virus scanner or something.
Two questions come to mind:
- Does it work in an elevated shell?
- If you run this under strace, does it show anything unusual?
We could take a look if you call
strace -o cat.trace cat /proc/partitions
and send the cat.trace file here (assuming it still doesn't work).
