WD "Raw Read Error Rate"

post #1 of 2
Thread Starter 
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 SMART value indicates a read event that "didnt go as planned". By this, it could be something as simple as the drive controller missing the intended block of data by a few bits, at which point it'll re-read that data properly and move on, or it could be caused by the disks or read/write heads failing. As you only have a few errors and they all cropped up immediately after a huge data transfer, its far more likely to be that the drive controller had a couple of minor internal glitches that it immediately corrected for.

Basically, dont worry about it unless it starts climbing nonstop. Also, dont use HD Tune for checking hard drive health, use Hard Disk Sentinel. Much easier to read and gives you all the info you could possibly want regarding the health of your drives.
