Hey *, I also had a lot of trouble with hard drives in the past... So just some more hints from my side :-) Dave Aitel wrote:

to get more proactive abilities, check out the smartmontools at http://smartmontools.sourceforge.net/ helps a lot in constantly monitoring the Raw Read Error Rate or HD Temperature...
One might think you could use dd to duplicate your drive. I initially tried this, and my results were not good. I did remember to use dd if=/dev/hda of=/dev/hdc conv=noerror (the noerror flag is important). However, this takes forever and a day. Basically it'll take all night.
I also had bad experiences with dd when it comes down to deal with physical data corruption. I can recommend dd_resuce which worked for me even when dd failed. It is also a little bit faster (especially when your drive hits bad blocks). http://www.garloff.de/kurt/linux/ddrescue/
involves not having to ever do this again. For those of you not in the know - you want a hardware supported (get a good modern motherboard) RAID-1 solution and you want to be able to swap out one of your two drives (mirrored) when Linux tells you that one is bad. You also want to
using RAID-1 is most of the times also okay as a software RAID configuration. Normally you do not see much more CPU load doing RAID 1 as software... Anyway its always a bad situation when your primary server fails :-). If you have the money you may also consider to buy a remote management solution which may also include a virtual floppy option.
