I have a 750W Corsair 750TX which should be plenty (if not overkill). |
41 |
Seems to have all the bells and whistles (though I wish I had bought |
42 |
the modular version). I definitely agree about the cheap no-name PSUs, |
43 |
I've seen some USD$10 ones go up in smoke after just a few minutes of |
44 |
use. |
45 |
|
46 |
Based on the little info I could find Googling it seems the most |
47 |
likely explanations are: |
48 |
|
49 |
IRQ handling weirdness (but that was more probable in older |
50 |
motherboards and kernels) |
51 |
ahci driver issues (I will reboot with the controllers in "legacy" |
52 |
mode to use the non-ahci drivers and see what happens) |
53 |
a bad drive, bad cable, bad controller, bad sector, something physically bad. |
54 |
|
55 |
Overnight I copied several hundred gigs of data (and still going) and |
56 |
the error has not been reproduced. Before installing, I did a full |
57 |
SMART test (a few hours) and a badblocks read-only test (even more |
58 |
hours) and neither showed any errors. I did not do a full read/write |
59 |
test, though. |
60 |
|
61 |
I haven't heard any unexpected noises coming from the drives (no |
62 |
clicks of doom), though I have so many fans going it may be hard to |
63 |
hear. |

Thanks. |
