Windows initialize disk device not ready

The file explorer opened but stood frozen for a couple of minutes in "not responding" condition. I then unplugged it. Now It shows in the device manager but doesn't show in file explorer. I tried reinstalling drivers but it doesn't help. I checked the Disk Management utility as described in the post here. It shows it as Disk 2 with the red-downwards arrow. When tried to initialize it with GPT partitioning, it says " The device is not ready ".

Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. After that I kept it plugged in for about half an hour. Thanks for your feedback. Thank you, DaveM!

I'll give it a try. So, for the moment, I'm using FAT If need be, I'll remove the drives and format them in NTFS using the connecting cables and power unit which I've done many times with many disks and see if it will work with that formatting. It's working now, sort of. Thank you, again, and I will try it if there are any problems. In any case, I'll keep the procedure handy for when I need it, either very soon or later.
