USB hard drives
One of the notes on this updates refers to improved compatibility with USB hard drives. I have an old PATA hard drive in a Metal Gear Box enclosure that would not mount properly for backups when connected to a USB 2.0 hub. Before 10.5.8, I had to attach it directly to the USB port on my Mac to run disk utility on it, make backups, etc. After this OS update, the hard drive now mounts and works properly when connected to my USB hub.
