WD "Raw Read Error Rate"

2 posts in this topic

The more I search this, the more confused I get.

I have a WD20EARX that was used in a PVR for a while, and a couple of days ago I shifted it into a PC. "Raw Read Error Rate" data was at 0 to start with. After writing about 1.5TB to it I happened to notice that the data value is now 3. What does this mean? I have a couple of other WD drives in the PC (one a system drive, the other for programs), and as far as I know the "Raw Read Error Rate" data value has never changed from 0.

That's fairly typical for the larger drives. The CRC steps in and corrects the data so there is no loss. Almost every one of my > 1TB drives from various manufacturers have accumulated a few of these over the years. It'd only be a problem if it starts incrementing quickly in a short period of time.
