I have a macbook pro 13 which i've modified to install a optibay with 1tb HDD to replace the optical drive. With 10.8, this was working as expected. I would delete a file, it would go to trash. just the way my normal boot drive works. With 10.9 i just noticed that when i delete a file, it gives me a dialogue box saying file with be deleted permanently. this is an error i'm used to on my NAS drives since they can't create trashes i guess. But it was a surprise to see my HDD give this error. i haven't tried it, but i'm guessing this error will also happen on external usb drives. with 10.8 usb drives operated normally. i.e. deleted files went to trash. maybe that has changed now as well. anybody else seeing this? can i do something to restore the old trash behaviour (yes i realize it might be a bug and apple will fix it) ? or is this something that apple has to fix?
