Thanks for responding. Well, unfortunately this is not a new one. I'm using it for the last two years. It had more than 930 GB of music — something I gathered through the last 10 years — and it is not easy to have a backup for such a huge volume of stuff. If I need to format the drive, it would be a huge loss for me. I got in touch with one of the professional agencies. They estimated the cost at $2000. The shocker drove me to explore avenues if I could do something on my own but there are several software options that promise to retrieve data from crashed hard drives. Can you suggest me what would be the best option or options that I could rely on? The HDD is Western Digital My Book Essential 1TB USB 3.0 / 2.0.
For me, it was to go to Computer Management -> Storage -> Disk Management, which was showing the external drive. Even though it had a healthy partition, I had to remove it, and add a new volume. The disk instantly came up in the Computer folder.
