For comparision, my RMAed Black 1.5TB performs better than this Black 2TB using the same system. Only this can explain the high RAW Read Error Rate and the low performance. Judging from the condition of the HDD I suspect this is a refurbished drive. All other major problem indicators remained at 0.(Relocatted sector, Current Pending Sector and Uncorrectable Sector Count) I am not getting any other warnings besides the RAW Read Error Rate. All online review shows this drive SHOULD be around 143MB/s Read and 135MB/s write. For example, My CrystalDiskMark benched at 500MB is 132MB/s Read and 127MB/s write. I have tried the following: AIDA64 2.7, HDTune 5.0, WD Data LifeguardĪll three SMART statues report Raw Read Error Rate 117(yep, increased from yesterday)īenchmark shows my WD Black 2TB is considerably slower than most online reviews. Windows 7 Professional SP1 with all patchesĪll Intel Drivers, including the Instel Rapid Storage Technology My system configuration is as below:ĪSUS Maximus Formula. I have tried multiple sata cables-with clips and without has 90 degree bent and straight. I feel for ya that is REALLY frustrating so i wish you luckīut i’m sure most people here would agree with cause (connection issue) but to be thorough i am curious can you look in the windows event viewer and see any messages related to your hard drive for the warning or errror categories ?Īlso do you have a SATA onboard nvidia controller ?Īlso you only mentioned that one smart value, are you getting any other smart values that look bad ?Īre you sure ALL the data on your drive is good ? Have you run chkdsk to scan your partitions ? I’d hate to think someone RMA’d their drive when they didn’t have to so i’m trying to suggest being as thorough as possible for YOUR sake not WD’s. I have some cables black sata that are the same but one of them had shorter metal strips inside… My point is here is there are different cables that are made totaly different so if there was some thatĪre different that you can borrow from another pc for testing i would do it…īear in mind its just mass produced plastic with a few strips of metal so sometimes they arn’t perfect. My motherboard has crappy connectors on the board itself and its really easy to get a bad connection with them because of how tight and short the connector hole is on the ports. On on of my sata cables before it would go in far enough, when i did that it pretty much cleared up the issue. i had to pry off the metal retention clip thing Using those may help or make things worse. Well like i said its *most likely a connection problem and if not my guess is there is a problem with the drive.īut i’m curious where are you getting these smart values from ?Īnd do you have cables that have two small bumps or similar so they click into place ?
