I have a WD 500GB external hard disk. It had been working fine on any computer systems that I used it on, for more than 5 months and all of a sudden it is not shown in the My Computer window. But it is still detected and installed correctly on any system that I plugged it into.
Here is a screenshot of diskmgmt. It says the disk is unallocated.
Any ideas how to solve this problem?
P.S. I already tried rebooting in safe mode, and rebooting again in normal mode. It didn't help. Also I have read many posts with similar problems but they do not exactly match my problem scenario and weren't of any help either.
