Hello Jeff, |
2 |

I've had 3 machines exhibit this kind of behaviour in the last few months. |
5 |
|
6 |
On the first machine, it was an intermitten IDE controller failure (probably |
7 |
related to heat and expansion of motherboard compoenents). I was able to |
8 |
bypass it by installing a PCI SATA controller. The way that I was able to |
9 |
figure this out was by running knoppix on it (I tried windows too, just in |
10 |
case). When running knoppix (and, that OTHER os), the problems still |
11 |
occured. |
12 |
|
13 |
The second and third machines were having problems because the wrong drivers |
14 |
were loaded for the motherboard IDE controller. On the first of these |
15 |
machines, I ran knoppix and it correctly loaded the drivers (I used lsmod to |
16 |
find them ;-). On the second of these machines, it was a production machine, |
17 |
and it took a lot of time because I couldn't just bring it down. I was |
18 |
getting "operation not permitted" when trying to enable DMA. Eventually, I |
19 |
had performed lspci, and saw the controller, then noticed that it was |
20 |
compiled into the kernel as a different controller. |
21 |
|
22 |
As far as it goes for your situation, I would recommend running knoppix to see |
23 |
if the autodetection can resolve it. If that doesn't work, it may be that |
24 |
it's simply getting confused between those two similar controllers. Does |
25 |
"hdparm /dev/hda" show any useful info? How about "hdparm -i /dev/hda"? If |
26 |
you try to make settings (such as set DMA "hdparm -d1 /dev/hda") does it spit |
27 |
out errors? I think hdparm may tell you more in this situation because the |
28 |
disc reads are insanely slow (1MB/sec should be more like 50MB/sec). It |
29 |
might be worth walking through this just to see if it gives you any errors: |

I hope this gives you enough to go on... |
