I have an 8TB western digital drive connected to my Linksys 1900ACS. It's configured and working fine, but installing hd-idle seems to have no effect. In luci I tried setting the disk to sda1, /dev/sda , etc. and it doesn't seem to have any effect.
Also tried installed hdparm and I get this
hdparm -S 5 /dev/sda1
/dev/sda1:
setting standby to 5 (25 seconds)
SG_IO: bad/missing sense data, sb: f0 00 01 00 50 00 00 0a 80 00 00 00 00 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Any ideas? The drive would spin down fine on stock firmware. I'm quite new to openwrt.
