 For the same procedure, I get
 
 [hauke@pizza] ~ # atactl wd1 checkpower
 Current power status: Active mode
 [hauke@pizza] ~ # atactl wd1 sleep
 [hauke@pizza] ~ # atactl wd1 checkpower
 atactl: wd1: Input/output error
 [hauke@pizza] ~ # disklabel -r wd1
 disklabel: /dev/rwd1d: Input/output error
 [hauke@pizza] ~ # 
 
 and dmesg says
 
 [...]
 wd1: wd_flushcache: status=0x5128<TIMEOU>
 wd1: IDENTIFY failed
 wd1: IDENTIFY failed
 
 I remember the "device timeout" line you quoted from netbsd-6, but have 
 not seen them on netbsd-7.
