[smartmontools-support]default hdparms? readahead=256? Re: WD 400GB xATA Drives

I've seen similar errors soon after bootup on a 400GB PATA Seagate
drive, but they have mysteriously disappeared so I haven't tracked
them down.
Have you checked if there is a difference in the hard disk parameters?
hdparm -i <drive>.
For some insane reason I haven't tracked down, drives not explicitly
set to known values may not contain "great values". My "readahead"
value seems to boot with a value of "256" for all of my drives.
Is this not a bit "excessive"?
