I expect the kernel cached the previous value. I expect you would need to trigger the kernel to re-probe the partitions again. Not sure but seems reasonable. (shrug) # apt-get install parted Then: # partprobe Or: # partprobe /dev/sdX The 'blkid' command also has a cache too. It might be necessary to flush it or tell it 'blkid -c /dev/null' to avoid it. See the man page for details. Bob
