chown -R results in Input./Output error (ubuntu Dapper Drake)
Thinking I am doing something smart, I recursively changed the group of one directory_name (with many subfolders) on my removable drive:
chown -R my_login_name:users directory_name
Previously the ownership was login_name:login_name
Well, I have a big problem now. I can not access folders, they have unknown size, ownership, group, date, etc. If I try to do anything, I get an Input/Output error.
Help! Is there a way to reverse/undo the damage?
Thanks for any hints
