I'm trying to put a drive to sleep with: |
4 |
|
5 |
hdparm -Y /dev/sdb |
6 |
|
7 |
But it immediately wakes up again. dmesg: |

The drive has only one partition in it (NTFS). I don't need that drive |
23 |
in Linux so I want it to sleep, but to no avail :P It's not mounted. I |
24 |
can't see any reason why it would wake up again with an "exception |
25 |
Emask" (whatever that is). |
