2016-03-07 My dad's computer refused to boot. The situation is such that it contains three hard disks, all of them a bit older. Thus they form one RAID 1 with one disk spare. The idea is to use these disks as long as they work and if one fails, the others take over. This way, I can lose two disks before trouble begins. As two of the disks have a lot of read errors, this is surely neces- sary. Now it seems as if the first disk is failing. I'm not sure, how- ever, why the system not simply tried booting the second disk. Well, I removed the first disk. It appears to be really too bro- ken now. Then have the spare disk be part of the RAID and ... the system's fine again. http://marmaro.de/lue/ markus schnalke
