The blinking light is a new feature in 8.10 - it blinks when the connection's in use. The blinking can be disabled if you don't like it - see here:


hdx and sdx are different ways of referencing storage devices. hdx indicates a plain IDE device. sdx indicates a SCSI device. However, a lot of storage devices (eg SATA and USB) are accessed through the SCSI system, so they're listed as sdx as well.
