Hi I have foolishly moved a time machine back-up file from my external drive to trash. My problem is now that I cannot delete it properly from trash. Moreover, I my external hard drive is acting up. I can´t eject the drive, I can´t write to it and I can´t delete or repair it from Disc Utility. The file in the trash has got ...inProgress and I have tried to empty trash with normal empty, secure empty and through Terminal. Time Machine has been set to off all the time. Any ideas on how I can solve this? Thanks in advance!
