A new drive should have no sectors that read over 10ms, let alone 5ms.
Russ,
I hate to start a new thread for this, but I finally tried out HDDScan and I'm curious about the results. I'm curous what you think of the results.
I have three 1 TB Hitachis (non-Enterprise) in a server. They are nine months to 1.5 years old and run 24/7, all in non-RAID mode.
About nine months ago, the server fell, running, from the seat of a chair onto the carpeted floor. I expected all three disks would be trashed. But after the fall, I ran "chkdsk /r" on all three disks and no errors were found. SMART still gives no warnings and no reallocated sectors.
I'm not sure the best way to post my HDDScan results. But I'll start with the Report table that seems to show all reads longer than 50 ms. The first disk, "Disk A", is a later three-platter model that was installed AFTER the accident. The other two disks, "Disk B" and Disk C", are original five-platter models that were running in the server when it hit the floor.

My question is: Are these "normal" results for a set of working 1 TB disks? Or should I be worried? One of these three disks (either "Disk B" or "Disk C") is the boot disk, running Win Server 2008 and Hyper-V". I don't know if that affects the HDDScan results.
Thanks,
