hmm, not seeing the same slow down when I boot from the Samsung EStool CD and run a diag which performs a surface scan... could this still be a hardware issue, or possibly something with the Solaris data format on the disk?
Rotating drives often have various optimizations to help recover from damaged servo sectors when reading sequentially, in that they can skip over bad areas and just "assume" that the position information is there, until they get an ECC fatal on a read. Until the drive wanders off-track, it just keeps reading until it eventually finds some position information. I'm guessing you have a physical problem with the servo wedges on that drive that only manifests itself in some of your access methods. Does the drive click or make any other noises when this is happening? For the price of drives today, I'd buy a replacement and look at swapping that one out. You can always keep it as a spare for later. -- Eric D.
