One of the partitioned HD icons has vanished from the desktop

500GB LaCie DESKTOP HARD DISK USB2 on Powerbook ti G4
I have 3 partitions on the Hard Disk -reformatted Mac OS Extended (Journaled)- and all 3 have always appeared on desktop as usual. I selected one of them and went to 'get info' and then selected 'no access' as an experiment to see if I could achieve this. After 'ejecting HD' in the usual way before switching off, and later switching on again the icon for this partition was not visible. If I go to Disk Utility the partition is there but as a white icon and not the usual orange icon. If I mount it, it turns into the usual orange icon but the name greys out. It still doesn't appear. I also verified and repaired it in utilities, but it passed as okay and not needing repair. I also switched everything off with everything unplugged overnight, but it didn't help.
Can someone tell me how to remedy this please?

Have you tried a permmision fix, not sure if it is going to help. You set the drive to no access, which as you see means no access.

Go to Applications>Utilties>Disc Utility and repair permissions on that drive if it is visible.

If that doesn't do it open up the terminal and type this
sudo chmod u+rwx "/Volumes/name_of_your_disk"

where you would use the actual name of your original disk instead of "name_of_your_disk"

Everything will be OK in the end.
If it's not OK, then it's not the end

Thank you Twist,
I've managed to solve this and remount the 'vanished' partition by using terminal. I typed in:

cd /Volumes

sudo chmod –R 777 ./name of my disc\number

The hard drive started making internal noises, and then I did a restart and it reappeared. Brilliant!
