External Hard drive detected but not mounted
When I used to have windows my 1TB verbatim hard drive (after a few months of working perfectly) started malfunctioning, It wasn't always mounted by my windows 10 OS. When I switched to Fedora I had the same problem. So far it hasn't worked on fedora. The external hard drive is less than a year old. I do not understand what prompted the problem since it was sudden.

fdisk does not show the hard drive either:

It does show up in disks though with the tag no media
Is this drive still under warranty? Does it still (at least sometimes) work under windows? Have you checked its SMART status/report?
It is under warranty but I lost the receipt (stupid I know). I haven't checked it on windows in a long time and since Fedora is now my one and only OS it doesn't seem necessary to test it on windows. how can I check its SMART status?
AFAIK
fdiskneeds the device:fdisk /dev/sdbin your case. Also, have you tried mounting it manually?mount /dev/sdb1 /mnt(or whatever partition)fdisk: cannot open /dev/sdb: No such file or directory
I received that error after running fdisk /dev/sdb. I expected this error since as I said fdisk does not detect the hard drive in the first place. Attempting to manually mount yields this error:
@Chadi I incline toward the faulty cable (or faulty usb controller) hypotesis. It seems connection is coming and going, you can see:
fdisk: cannot open /dev/sdb: No such file or directory(/dev/sdb isn't there) andmount: /mnt: can't read superblock on /dev/sdb.(now /dev/sdb is detected)
