Uh, ok.

Ok, the fs type is UNIXFS, so TAS won't be handled like Samba and it
won't get any workarounds we created for Samba. Given that
FILE_PERSISTENT_ACLS is true, the FileIdBothDirectoryInformation info
class will be used by Cygwin. That's probably where it goes downhill.
The actual status code would be interesting now.

There are two easier solutions, maybe. One is, try the latest Cygwin
DLL from http://www.cygwin.com/snapshots/
Just rename the currently installed DLL and drop in the snapshot DLL.
It will give you some warnings and maybe some paths won't be correct,
but it should at least allow to call ls /cygdrive/h. The snapshot
DLL will print the exact status code when the NtQueryDirectoryFile
call fails.
Alternatively you could try to write a little application which opens a
directory handle on that drive and then calls NtQueryDirectoryFile along
the lines of Cygwin's fhandler_disk_file::readdir implementation, like
this:
#include <windows.h>
#include <ddk/ntddk.h> /* I think */
HANDLE h = CreateFile ("H:", GENERIC_READ, ...);
if (h != INVALID_HANDLE_VALUE)
{
status = NtQueryDirectoryFile (h, ..., FileIdBothDirectoryInformation, ...);
if (!NT_SUCCESS (status)
printf ("%p\n, status);
status = NtQueryDirectoryFile (h, ..., FileDirectoryInformation, ...);
if (!NT_SUCCESS (status)
printf ("%p\n, status);
}
CloseHandle (h);

That's your choice and I respect that. But it's hard to support all
possible combinations of file systems with their kinks and bits.
