So I'm guessing either you had the problem and figured, "let's upgrade, see if that fixes it" (not a bad plan), or you are a regular upgrader (also good). Can you say if the problem started with an upgrade? Or did it occur between upgrades? ... > sd0 at scsibus1 targ 0 lun 0: <ATA, WDC WD1003FZEX-0, 01.0> Any possibility you have a bad disk? A few times in my life, I have seen a bad disk that would have issues reading from the drive, but succeed after a few retries, before it threw an error back to the OS. It would then reset its retry counter, and have the same problem on the next read...and the one after that. Result: horrible performance, but it "worked". (granted, I've been doing computer support for almost 40 years now and I can think of two cases of this happening that left me scratching my head for a long time, and maybe a couple others similar to this that I don't recall so vividly, so not exactly a common problem...but not unheard of, either.) ...
