I know it is temporary. The problem is that I issued hdparm -X /dev/hda, |
| 16 |
and hda holds /, swap and everything. The system was in multiuser |
| 17 |
mode. I fear that the command could have messed up the hard disk, |
| 18 |
and caused data corruption. |

I have taken a look at the hdparm source code, and I see that |
| 20 |
hdparm -X /dev/hda is indeed equivalent to hdparm -X 0 /dev/hda |
| 21 |
But I still don't know if this is safe. I cannot continue to |
| 22 |
investigate the source code because it gets to an ioctl |
| 23 |
about which I know nothing (I think this would be a *lot* of |
| 24 |
research). |

|
| 26 |
I have since fsck'ed all relevant partitions in /dev/hda and they |
| 27 |
came up clean. |
| 28 |
Am I safe? |
