Hello,
I have two 500 GB Caviar Black drives and one of them is displaying some peculiar (to me anyway) SMART numbers. Basically, on the drive on which I have my OS (multi-boot, various flavors of Windows) the SEEK ERROR RATE infrequently flips between 200/200/0/0 and 100/253/0/0 (current/worse/threshold/data) and back again. This happens in no predictable fashion (ie, not just between boot ups). The second drive’s SER stays at a constant 200/200/0/0.
I have recently had some infrequent system hangs at Windows startup but a reboot starts up just fine.
The drive models are both WD5002AALX and are a bit over 5 years old.
The other SMART data seems fine but for completeness sake, I’m listing the SMART data reported by HD Sentinel below (sorry for the poor formatting)…
Is this behavior normal or should I be pro-active and replace the drives? Any suggestions would be appreciated.
