CentOS - Oct 2008 - External ext3 USB Hard drive and selinux

I was directed to post this on the mailing list. See the following forum post 
as a reference.

http://www.centos.org/modules/newbb/viewtopic.php?topic_id=16710&forum=42

I formatted my external ext3 372GB USB hard drive in ubuntu and now want to 
use it 
in Centos. I made sure that my group/user numbers were the same. I was not 
able to write to the mounted USB hard drive (HD). I suspected selinux and 
shut it of and I was able to copy the file! I set selinux back to enforce and 
rebooted. I like the security features of selinux.

I tried:
1) chcon -v
2) restorecon -Rv /media/disk
3) cp -P

and still am not able to write to the USB HD. The sad part is I can delete 
files from the USB HD. See forum post for details.

I tried it in fedora 9 and it is able to write to the USB HD

I tried an 32GB USB memory stick in Centos 5.2 and it worked!
I am wondering why it doesn't work for my USB HD? The only difference is the
the size.

Your help would be much appreciated.

Try rebooting in permissive mode then inspect the avc messages.

Double check the permissions of the mount point before and 
after mounting the device.
