True, and why we have off-site backups as well. But a high quality disk controller [and other hardware too], and file systems with parity checking built-in (think ZFS, Btrfs etc) goes a long way to prevent issues as you describe. As for Florian's issue with the "corrupted file system". I would highly suggest he investigates why the problem occurred in the first place, so that it can _truly_ be fixed. The wonderful world of Windows Administrators have corrupted the minds of so many system admins with the advice: "reboot and the problem should be fixed". That's the worst advice ever, and it fixes nothing! Paul Venezia said it best: "When in doubt, reboot? Not Unix boxes" http://www.infoworld.com/t/unix/when-in-doubt-reboot-not-unix-boxes-061 Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
