I did leave the battery connected, in fact I didn't remove any of the connectors either. After removing the key, it appears the CIC headunit is still receiving power (it looks like a mainboard led is lit), but you can hear the hard drive spin down immediately following shutting off the car.

Unlike SATA, IDE is not hot swappable, but if the HDD is spun down it is a good bet that the heads are parked and it is safe to remove.

Also, QNX is designed for harsh environments, so it is quite tough to corrupt the QNX filesystem.
