[Ubuntu] External hard drive is read-only

Yesterday I installed Ubuntu on my PC, but I met an issue about the external drive is always the read-only. As the hard drive was the destination of my internal minio server, so I have make it writable too.

Error: mkdir: cannot create directory ‘abc’: No such file or directory

When I ran the df -T, it shows like

/dev/sdb2      fuseblk  3907000316 278934580 3628065736   8% /media/username/InternalBackup

I labelled the hard drive name as InternalBackup in the Windows OS before.

THe above disk mounting is actually done by the Ubuntu. When the Operating System is started, it was already like that.

In this case, the solution is that

sudo umount /dev/sdb2 /media/username/InternalBackup
# If the above does not work, just manually unmount it from the desktop UI

sudo mount -o rwx /dev/sdb2 /media/username/
# Compare to mount the full hard drive name, we just need to mount it to the username level

After searching a ton of solution, this method worked for me.
