You're stuck between a rock and a hard place as they say, assuming you
plan to stick with FAT32 as your file system type (and that you're not
interested in supplying a patch to Cygwin ;-) ) You're right that
'ntsec' only works for NTFS. Unfortunately, it's been determined that
'ntea' only works for FAT partitions from NT/W2K/XP. It doesn't work
on FAT32. This is a bug.
Sorry,
