The setup:
Raspi2 B+ running on a 8GB SD card and 32 GB Sandisk Cruzer Orbit for at least a year. I mounted the drive to my torrent download directory like this:
sudo mount /dev/sda1 torrents/downloads/usb
It's been running smoothly until one day I wanted to do a reboot and it was not working. I can always ssh back to the machine despite it says that it's going to reboot/shutdown. I did a "shutdown -h now" and then unplugged the power, plugged it back.
When I mounted my drive back, the fun started:
pi@raspberrypi ~ $ sudo mount /dev/sda1 torrents/downloads/usb
mount: block device /dev/sda1 is write-protected, mounting read-only
Online research suggested that i remount so, I unmounted and tried this:
pi@raspberrypi ~ $ sudo blockdev --setrw /dev/sda1
pi@raspberrypi ~ $ sudo mount /dev/sda1 torrents/downloads/usb
mount: block device /dev/sda1 is write-protected, mounting read-only
pi@raspberrypi ~ $ sudo mount -t ext3 -o remount,rw /dev/sda1 torrents/downloads/usb
pi@raspberrypi ~ $
I tried to create a file and edit it using sudo vi and this is what I get once I try to save the file:
pi@raspberrypi ~ $ touch torrents/downloads/usb/test
pi@raspberrypi ~ $ sudo vi torrents/downloads/usb/test
The error I get is:
"torrents/downloads/usb/test" E667: Fsync failed
So basically, my usb drive is in Read-Only mode. Here are some diagnostic details from dmesg:

And using fdisk I get:
pi@raspberrypi ~ $ sudo fdisk -l

I tried to clean the partition using parted as well:
pi@raspberrypi ~ $ sudo parted /dev/sda1
Warning: Unable to open /dev/sda1 read-write (Read-only file system). /dev/sda1 has been opened read-only.
Warning: Unable to open /dev/sda1 read-write (Read-only file system). /dev/sda1 has been opened read-only.

This is my dosfsck results:
pi@raspberrypi ~ $ sudo dosfsck -v /dev/sda1
dosfsck 3.0.13 (30 Jun 2012)
dosfsck 3.0.13, 30 Jun 2012, FAT32, LFN
Logical sector size is zero.
pi@raspberrypi ~ $ sudo dosfsck -a -f /dev/sda1
dosfsck 3.0.13, 30 Jun 2012, FAT32, LFN
open: Read-only file system
I have tried a lot other things like using parted to delete the partition, HDDGURU's low level format tool - nothing work.
Can anyone give any lead on this? I'm willing to try anything.
Thanks a lot!
