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). |
