I had my external drive that holds my 424 GB Aperture 3 database (one of them) on it give me a bunch of error messages tonight saying it couldn’t read the file cos of a permissions error.

Yesterday, I plugged the drive into a Belkin USB 3.0 four-slot extender instead of directly into the Mac.

Once I unmounted the drive and then plugged it directly into a USB 3.0 port, the problem went away….

Not sure why Aperture could/would not read the files while going through the Belkin bridge but it would not.
