I installed GPT disk manager about two weeks back. I formatted an external 2TB Seagate drive and copied some files into it. Strangely for the last few days, I am not able to see the drives nor the files in it. When I go into GPT DM, I am able to see the drive and the partitions. But when I go into Windows explorer, I am not able to see any drives. I un-installed and re-installed GPT DM a few times to no avail. To double check, I connected the same drive to a Dune media player, and I am able to see the partitions, the drives, and the files. I use a Dell 8600 as my laptop and the GPT DM is loaded on that. The GPT DM now shows two partitions, when there are actually three partitions in the drive. Dune also shows three partitions and three drives. What am I doing wrong?
