Gerhard, ha-ha there is no such thing as "just best something" :-) Talk to service (or sales) personal about HDD reliability on general. They'll tell you horrible stories about some brands for some periods. That's kind of magic; nobody could swear that a single HDD wouldn't die next second, even non-powered one. (I'd rephrase Elton John: "Sorry seems to be the harddisk word" :-) And in contrast to, say, CDR you can't just place its plates into another HDD, or buy just another dozen of them to make extra-copies. If they were "reliable" there was not so much fuss about RAID, SMART, File System reliability etc. By the way, file system was not specified; the worst one for my apps, I've ever bumped into, was FAT32. With that FS one should expect some system files get corrupted eventually "by design". Regular clean reinstalling was the only way to go. > I, like the vast majority of computer users, don't have a complete > set of test cases for my system configuration :) That's the point: the cost of validating (testing) of the new long-run situation is much higher than the cost of just getting to the start position once in a while, like for steppers.
