我把一顆1TB隨身硬碟(檔案格式NTFS)透過usb hub接到raspberry pi，
作業系統是raspbian，透過ssh -X登入，掛載指令是
sudo mount -o uid=pi,gid=users,umask=027 /dev/sda1 /mnt
掛載後/mnt與硬碟內檔案的owner與group及其權限都如預想的一樣，
但是想用dd測試寫入速度時，系統回應"拒絕不符權限的操作"，
後來又簡單的嘗試寫入，如mkdir或touch，
系統回應"此項操作並不被允許"或"拒絕不符權限的操作"。
請問是哪邊的權限沒有處理好呢？
ps. 讀取隨身硬碟內的檔案到raspberry pi的SD卡倒是完全沒問題，
就是寫入完全沒轍...
