I am having 320 GB transcend hardisk,its partition was invisible in my computer,but it became visible in partition magic software alongwith data which can't be copied.
Please rescue me

Is this the only partition on the disk? It sounds like it is, and it sounds like it used to be visible but now is not. Is this correct?

Is it a laptop?

How big is the hidden partition
