The media is write protected (19) - passport not accessible - need help

Hi, I have nearly the same problem, My desktop hard drive is not being recognised by My Computer, and if I try to access it using disk management it appears to be unallocated and needed for initialisation.  If I try to initialise the disk, a window shows up saying “The Media is Write protected” and that doesn’t allow me go any further.

Any suggestions…??  How did u solve your problem?

Thanks…
