Hello,
thanks for attention to my issue.
it seems more info is needed.
(a) the motherboard
GA-H61M-USB3-B3 (v2.0)
(b) kernel
9front
(c) fs configuration
cwfs
pseudo RAID1 configuration.
filsys main c(/dev/sdC0/fscache){(/dev/sdC0/fsworm)(/dev/sdD0/fsworm)}
these hdds are 2.5" sata 160GB and 320GB respectively.
(d) standby?
not in standby mode.
(e) dma?
dma was off
dmactl 00000000 # from both /dev/sdC0/ctl and /dev/sdD0/ctl
when I found the error message, I suspected the disk is dead.
so I tried if the disk (/dev/sdD0) was readable.
for example I tried to read /dev/sdD0/nvram, but was unable to read.
I powered off the machine, dismounted the disk, and attached to other machine.
I retried to read the disk. the result was OK.

the following result is from fsworm blocks of the disk that was in trouble.
2315947 readable, OK, last dump of /2013/0517
2315948 readable but garbage , that should be the superblock of
/2013/0518
2315949 readable but garbage
2315950 readable but garbage
