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