When I was talking about permissions, I was talking about permissions on
the native Windows devices, not any permissions on Cygwin files. 

The strace output shows that you don't have permissions to call
DeviceIoControl(IOCTL_DISK_GET_PARTITION_INFO) or
DeviceIoControl(IOCTL_DISK_GET_PARTITION_INFO_EX) on the devices
representing the partitions in the native NT device namespace, i.e.,
\Device\Harddisk0\Partition0, etc.
