I don't know if this is the right area to post this, but it is related with security at some level,

A couple of weeks ago i've erased some files from my USB HD, btw, a Wester Digital of 160Gb, now everything was ok, until i tried to erase the Wastebasket, to my surprise, it started complaining that the files previously erased from the HD were read only?!?!?!? If i erased them in the first place how can they be read only???

I've tried everything, it created a folder .trash-<username> on the HD so i tried sudo rm -fr to force a remove, but still no luck....

Any ideas?

Thanks.

i believe you need a cap R not r
