permissions on a folder.

[xptweakerntn]

i mounted my harddrive at /home/Matt/Data, that works fine, but i want ot give myself permissions to read/write. i tried switched to root using su -, then chmod -r /home/Matt/Data, now i can't even view the folder, i don't think i even have read acces now. help, i used Ubuntu for a while, but i like this better, first day of using it!

can you post the output of ll /home/Matt so we can see the current perms. if the hard drive formatted with ext3?
