I have a system running Centos 5.5 with SAN drives when I was checking them thru Partitions on Local Disks I could not perform any task on them because the link to edit was gone. Using firebug I was able to add some text to the link and it appear. See the screen shot for more details.
Blank link overwritten using firebug
Interesting, looks like a bug in parsing the fdisk output.
Could you attach the full output from the command :
fdisk -l
on your system? Also, what does the /proc/partitions file contain?
