How to fix an exFAT drive being write protected

Recently I connected an external Verbatim RAID HD to another Vista computer, while copying files to it the USB connection was broken and re-established (without touching anything).
After the drive again had mounted the drive I was coying files to was write protected! Huh?

Solution: run "chkdsk /F"

"Error 0x80071AC3: The operation could not be completed because the volume is dirty"
This is the message I got from Windows backup as I tried it to see if it would give any other message than "Write protected".
So the drive got "dirty" after the abrupted disconnection and running checkdisk on it to fix any errors will remove the "dirt".

At first I ran  "chkdsk /R" but that did not work so I ended up running "chkdsk i: /F /R /X" but it would probably be sufficient with only /F as is also worked for this guy "McoreD".

The checkdisk output: (fixes the problem even it states that there was no problem ;-) 
C:\Windows\system32>chkdsk i: /F /R /X
The type of the file system is exFAT.
Volume Serial Number is 80DA-01EE
Windows is verifying files and folders...
Volume label is exFat.
File and folder verification is complete.
Windows is verifying free space...
  2041292 free clusters processed.
Free space verification is complete.
Windows has checked the file system and found no problems.

Im trying this out on my Hitachi Touro Pro 2TB, and it's stuck at "Windows is verifying files and folders..."

Any clue how long this should take? There's only about 300gb of used space...

BTW the HDD is formatted exFat, for cross-OS support.

The drive operates fine, but accidentally was unplugged a few days ago. Still works, but I get the chkdsk popup ever time I plug it up, and I can only read from now. Really annoying...

My exfat 2tb hitachi touro drive experienced this same problem. I would try to alter read only and it would say "write-protected".

I tried the full chkdsk /f /r /x but it was taking AGES. Well days more like.

Canceled it and chkdsk /f worked just fine. Can change files now. Took minutes.....versus the days I was dreading.
