Right click on the Cygwin Terminal icon on the desktop, choose the
item "Run as administrator".

Here's what I see for all partitions in the trace output:
460 21259 [main] cat 553 format_proc_partitions: DeviceIoControl
(Harddisk0\Partition0, IOCTL_DISK_GET_PARTITION_INFO{_EX}) Win32 error 5
Win32 error 5 is ERROR_ACCESS_DENIED.
So it appears that the OS access is denied for some reason. I tried
again on Windows 7, this time with a non-admin account, just to be sure,
but I still can see the partition info. Yesterday I tried with an admin
account, just not in an elevated shell, so this may have been an
important difference. Apparently not so.
I have no idea why your system has different permissions, but at least
you should be able to see the info in an elevated shell.
