Can't delete to trash

[tinmice]

I have a fat32 drive mounted as I used to share it with a windows partition. It won't let me delete to trash and forces me to remove the file permanently each time I remove something. Although I am deleting the file, it is nice to have it stored in the trash before I definitely want to delete it. The .trash file is definitely there, but it refuses to let me delete to it.

The file is owned by root, and in the plugdev group, I'm not sure if this makes any difference.
The line used to mount it in fstab is :
UUID=48DF-B7BA /media/beta vfat utf8,umask=007,gid=46 0 1

I know I could reformat the drive to ext3, but there is a lot on it and it would be a fair amount of hassle to do so.

try changing umask=007,gid=46 to umask=0000 This will at least eliminate permissions issues on the mount.

Changed them to umask=0000, group is now plugdev as well, but still no change on the deleting front. What is plugdev?
