Seagate HDD SMART errors

Hi,

I have a SATA Seagate Barracuda 7200.10 ST3400620AS drive that seems to work fine, but smartctl shows me a large number of errors accumulating on Raw_Read_Error_Rate, Seek_Error_Rate and Hardware_ECC_Recovered. These number count up steadily so they don't seem to be some benign attribute that's being misread.

I'm told from reliable sources that any nonzero Raw_Read_Error_Rate is a sign of pre-failure so normally I'd be inclined to RMA the drive. In fact that's what I did with the first two that did this.

That's right, this is the third drive that's shown this exact same behaviour.

Should I be worried or is there something peculiar about this type of drive?

thanks,
Greg
