I have made my Transcend USB 3.0 pendrive into bootable ARCH-LINUX key using dd command. After that it become read only and I was not able to use it. So I formatted as MBR with NTFS partition using Disk Utility in Ubuntu and there were no errors, but when I try to use it, it saying read-only and not allowing to copy anything.Here is the screenshot of the error.
I had tried reformatting as GPT,the same error. I have tried EXT4 also.I have ran fsck command also, it says everything is clear. The following is the output of dmesg | tail -n25

Update: This is weird, I have formatted as FAT, I have checked the permissions, it is normal (-rw-r--r--). I have opened Terminal and used mkdir and a directory is created. I am able to create files also from cmdline, but whenever I try to access through nautilus , the error mentioned at the start is occuring. I have checked in my friend's laptop, there is no problem. Still can't understand the problem.
