Give the drive a little bit more time to complete the STANDBY IMMED command.

The ATA spec seems to suggest it may take up to 30s.  This seems a little bit
long.  To quote Theo: "by that time some drives have probably parked their own
heads in boredom".  But it shouldn't hurt unless your drive is seriously
broken.  Makes some laptops suspend much better.
