iTunes 8 store arrow links sucks, how to disable them
In iTunes 7 there was an option to hide them, in iTunes 8 there isn’t. This sucks. Close iTunes, open a terminal and write:
defaults write com.apple.iTunes show-store-arrow-links -bool FALSE
Cannot delete directories on fat32 filesystem under leopard
FAT32 formatted drives can not handle unix permissions at all.
You can not do chown, chmod or any of that stuff. In particular, if a file was locked in windows, it will be read as having an immutable flag in OS X. The only way to change it is by mounting the drive in windows.
You must open a dos window from inside windows and type:
attrib -r -s c:\foldername
and hit enter.
If you have long folder names or ones with spaces in the name it gets a little tricky guessing at the dos name equivilant ~1 etc. If you can’t get the dos name on any folders then rename the folder to a 8 letter name first then run the attrib command. Afterwards when you boot back into leopard, the locked check marks will be gone.
