[ubuntu] Lost Mount point after reboot

I am running Ubuntu Server (latest updated )on Vmware ESX 5.
I have mounted 60 GB Disk , disk is working fine i have copied the data in Disk . However i found issue every time i reboot the server i lost my mount point for the disk mounted disk .
- I ran MIBWalk to confirm that is true you can see the 60gb "/mnt/60gb" missing after reboot . I need to know if this is known issue ? or is there any fix for this to made that change permanent ?
