Beware, that probably a non-Linux disk (USB drive?) They don't do permissions very well (MSDOS/NTFS). Let's check:
mount | grep "/media/pc"
What does it say?
Can you also give me the output of:
ls -la /media/pc/Disk1/temp/test/Linux/
It should look like this:
$ ls -la /opt/PC\ Building\ Simulator/Linux/
drwxr-xr-x 3 root root 4096 Mär 16 20:29 .
drwxr-xr-x 3 root root 4096 Mär 18 12:51 ..
drwxr-xr-x 6 root root 4096 Mär 16 20:29 PC Building Simulator_Data
-rwxr-xr-x 1 root root 27977372 Jan 19 14:06 PC Building Simulator.x86
-rwxr-xr-x 1 root root 27505776 Jan 19 14:06 PC Building Simulator.x86_64
If the first column does not match, we have a permission problem.
Furthermore, do note that the printf command I published is geared towards an /opt installation. You cannot just use that and expect that part to work without adapting paths.
