I've had a problem similar to this with a handful of my USB2 drives.
It happens mostly when copying or reading very large files.
What chipset does your USB/FW enclsure use? I think it might be a
problem with this chipset, OR even the usb bus (mine's a VIA chipset).
# lsusb
Bus 005 Device 005: ID 067b:3507 Prolific Technology, Inc.
[...]
However, mine doesn't specifically go read-only since I use
gnome-volume-manager to mount and it remounts it after the reset
properly.
You can try and play with your fstab settings 'default' to see if it
behaves differently.
man mount
and check the options for ext2/ext3 filesystems.
