I have a 500GB WD external drive. I was using it fine with my windows 7 laptop Then I needed to save some data from my windows 10 laptop, so I plugged it into that laptop. It made that connect sound, but would not show up in windows explorer. Okay, so now I went into system management, manage disk drives. It was listed there as disk 1, but under that it said not initialized. And wen I right clicked on the disk, it said "Initialize with MBR or GUID, and GUID was prechecked. Anyway, I did that, but still no luck, it said cannnot be done, and some error I forget what exactly. I then did it with the other option checked. It again gave some error message and said cant be done.
Now the hard disk is not even being read on the original windows 7 laptop, and I see the same disk not initialized message in system management. What should I do, I dont want to lose all the data on my external hard drve
