WD Black 2.5 sata drive slow on windows 8. Sector size is 4k. What gives? 40MBps write.
This is a brand new WD black scorpion 500gb drive, on a brand new Zotac Zbox Nano CI320, quad core with 4gb of ram and Windows 8.1 x64.

Take a look at the pic and see from left are two USB 3.0 external drives and the last is my internal sata C drive that is showing issues. SMART scan came back A-ok! Kind of clueless here.



Update Back with some better news, after uninstalling the drive in device manager, booting into safemode then out again, I got this and confirmed it through about 4 more of the tests:
*note: the dip in data speed towards the end was from me doing something else with the drive while testing.


Update Tested again after 20 minutes since test above, it's back to slow 40mbps write speed :(
Testing on another system now! Then RMA if need be.

As it stands now: Sometimes getting full speed, mostly getting capped 40MBps write :(

Could someone please take a look at the SMART data and tell me if anything looks off to you?


Well guys, I think I've finally figured it out. It seems to have been a temp issue. I took some action to reduce temps, and attached two big solid copper blocks with thermal paste to the label side of the hdd. Temps now are going from 50c-60c variably. I'm probably going to make use of my eSata port on this thing, and relocate the internal drive to an external enclosure and eventually put in an SSD in the near future. :) My guess was the drive was going into a low power mode to reduce temps. That's the only thing I can think of.


Question: How do I increase sudo password remember timeout?
Answer: Disable sudo timeout with this command:

sudo sh -c 'echo "\nDefaults timestamp_timeout=-1"&gt;&gt;/etc/sudoers'


To re-enable sudo timeout with this method:

sudo sed -i "/Defaults timestamp_timeout=-1/d" /etc/sudoers
