I have recently formatted an external hard drive for use with Ubuntu 14.04 using GParted. I formatted the drive to Ext4, and everything seemed to work until I tried to copy files to the drive, at which point I was stopped with an error saying that the device is read-only. I have read many other questions here and elsewhere regarding changing permissions and remounting, but I have been unsuccessful with all of them.
Here's a picture of my permissions window for the drive:
And since I've seen requests for it in other places, here's an output of sudo fdisk -l: http://pastebin.com/GSpNGSJU (/dev/sdh/, the 2 TB drive, is the one I want to write to. /dev/sda/ is my internal hard drive.)
I'm really at a loss. I've tried remounting the drive with various suggested options, I've tried recursively updating permissions with sudo chmod, I've tried reformatting to make sure I'm not on NTFS - In short, I've tried a lot of things, but I'm so frustrated now that I'm having a hard time knowing if anything that I've done has actually been done correctly. What's more, my particular question doesn't seem to be answered elsewhere (unless I haven't looked hard enough), so there's that.
Hopefully I'm missing something simple, but how do I make it so that I can actually write to my hard drive?
sudo mount -o remount,rw /dev/sdXBdoesn't work? (X=drive,B=partition)sudo mount -o remount,rw /dev/sdh(without the 1), and that threw an error, so I went with partition 1. That went through okay, but the drive is still read-only.sudo fdisk -lagain, I can confirm that/dev/sdais my internal drive due to its many recognizable partitions and/dev/sdhis my external drive by elimination. I triedsudo mount -o remount,rw /dev/sdh1, and that executed without error, but I still can't write to my drive. Would something as simple as a machine restart affect this? Edit: Oh, and what do you mean by different port? There is only one listed partition./etc/fstabfor this device?
