I'm not sure what it is called, but it seems infectious! I have a drive (in a |
43 |
laptop) which I recently zeroed out with dd and fsck -c for good measure, |
44 |
before I installed gentoo on it. Yesterday, I tried a long test, but it won't |
45 |
complete. It reached "10% remaining" and it stayed there for a few hours. I |
46 |
will repeat the test to see if it gets through this time, but I am worried |
47 |
that it's on its way out. |

Oh well, I may install an SSD if it fails. |
