mounting ext2 drive as different user than root

Is it possible to mount an ext2 drive in fstab as a different user than
root? uid=myuser doesn't work as it does with vfat.

I'm trying to set up samba and share 3 large drives to windows machines
on my local network and I keep getting the permission denied error. I
believe it is because the owner and group are both root on the drive
with 700 permissions.

I've been trying to figure this out all day. I've read the fstab and
mount man pages as well as samba smb.conf docs without success. If its
not possible to mount it with anyone other than root then that is fine
if I can make it so samba will share the thing out with write
permissions to all users. I've gotten the vfat drives to share in samba
and be writeable using a guest account only, but not a user (other than
setting the guest account in samba equal to that user)
