I found a nice tool
http://smartmontools.sourceforge.net
but there are some problems for sata, cause sata is recognized in my 2.6.10 kernel as /dev/sda scsi...
and the drivers in kernel 2.6.10 do not support S.M.A.R.T ... I could use the libata, but there is a possibility this would cause problems with my onboard ich6 intel ...
I'll try it anyway, if I can get my sata drives to be recognized as /dev/hdx then it should work, works fine with my ATA btw !
thx a lot
