I recently copied a bunch of data back from an NTFS drive I had used for backup, which had NTFS permissions of Everyone - Full Control. The copy was done using Linux Mint, with the 2 drives slaved and mounted. I had turned off Journalling on the Mac OSX HDD before the copy, and turned it back on afterwards.
Despite copying it into the Mac (admin) users' home directory, I've lost all access to most of the files.
System has Read/Write, whilst Everyone has no access, and the User isn't even listed on these files. The Locked checkbox also appears ticked.
I tried repair permissions from a LION recovery disk.
I tried the following from a top level directory:
sudo chmod -R u+rwx *
...and it said "Unable to change file mode on . . . Operation not permitted"
I also tried to give myself read/write permissions using the Finder:
Right-click the "cdstuff" folder, and "Get Info". Under "Sharing & Permissions", click the lock icon to enable edits. Now give "Read & Write" access to everyone. Click on the little tool/widget icon, and select "Apply to enclosed items."
And it simply fails, leaving the sub directories as they are.
What's the OSX equivalent to Winodws "take ownership" and then "assign full control and propogate to all enclosed items"?
Thanks for any help,
ok, output looks like this after Daniel's help below:

The top Aphex twin files are now accessible after some messing around
i've no idea what the "wheel" entry refers to - it's not a group or user on this machine
Can I run that command on the whole directory? (there are lots more directories I need to fix...
