I have been working for the last four hours to format my external hard drive. At first I tried right clicking on it in nautilus and selecting format. I selected NTFS and tried to format it. I got some error shortly after saying something had timed out. Next I tried formatting it with gparted which is annoying since every time after I use it I get some sort of D-Bus error when I try to access my hard drives. I used gparted to give it the NTFS file system and restarted my computer. When I tried to open the drive in nautilus I got an error about the drive having a pending operation.
Next I decided to try the ext4 format. I got the same error when I tried to format it through nautilus, but it seemed to work when I did it through gparted. I was able to mount the drive and copy some files. This is a backup drive so I went to copy a folder of 600 GB size with some 12000 different files. At first the copy was really fast going at almost 100 Mb per second but at around 2 GB it became painfully slow as in maybe 3 Mb per second. It did not look like much disk activity was happening with my computer and it was just stalling for some reason. I then cancelled the copy and removed the drive. When I plugged it back in I got the pending operation error again.
Next I tried to boot into windows to format it and of course that went horribly as well. The windows format tool either didn't recognize the drive or when it was plugged in actually crashed windows. When I did get the format tool to finally see the drive I tried formatting it and it just said formatting for over an hour.
I would think that this issue may be with my usb drive but I have had similar unresolved nightmares trying to format flash drives on ubuntu 15.10. Also I tried to format it on ubuntu on my other computer and had the same issues. Any advice?
