Cannot empty the trash after transferred time machine backups.
I purchased a new larger capacity external HD for time machine backups. I changed time machine to use the new drive. All good. Backups started appearing on the new drive. I then moved the backup files from the "old" drive to the trash. Moved, no problem. Now I cannot empty the trash. I did "get info" on the old drive and unlocked the lock in the lower RH corner of the drive panel. Now after selecting empty trash I get all files cannot be deleted and other messages. The trash doesn't empty. I have two backup files in the trash and cannot delete either. I tried to move the file back to the original HD and them reformat but I cannot move it either. I'm stuck. Any suggestions?
