I've bought a new Seagate Expansion Portable Drive 2TB with exFat format. It works normally on Windows. On Ubuntu 18.04 I tried to mount the HD but failed.
I found advice to install exfat-fuse and exfat-utils (exfat 1.2.8). I've done that and still the HD is not mounting.
I tried to format the hd to NTFS but failed. I formatted it back with success to exFat. Still Ubuntu does not mount the HD. On disk it just mention 2TB block device. No partition.
Tried to format using mkfs.exfat but I get an Input/Output error. Checking on Windows for drive error found nothing wrong.
