I updated Intel(R)_USB_3.0_eXtensible_Host_Controller_Driver with one compatible with intel's 4-th generation cpu's and it works good luck! So it is not a "drive going to sleep" sort of problem.The drive is AC powered (not USB powered). I am going to try Keep Drive Spinning as a test. Clearly written and a life saver. get redirected here
Apple no longer manufactures computers with physical PCIe cards so the newer OS X versions are designed to cut power to the PCIe slots when put to sleep. after trying everything above this is what worked. Sick and tired of this happening as it's badly impacting on my workflow. So what do I have against RAID? http://www.sevenforums.com/hardware-devices/300403-raid-0-volume-disconnects-itself.html

The expensive hardware and brains on those raid controllers is for the overhead associated with calculating and distributing parity across all of the drives.

You mention 4 other possible causes for data-loss in your article but I am afraid I have to admit that I have never EVER lost data that way. Works great.

Since I'm not familiar with either one of your systems, it's hard for me to understand why it works great for one, but is barely noticable on the other...

He podido recuperar un RAID 0 de 4TB con informacion muy importante. That HD was NOT connected to the HUB but to my makeshift extension running straight into the Mac. That's not how statistics works :) If you personally have hard drives that don't fail, it means that someone else has twice as many that fail. Previous OS had no problems.
It actually finishes the test all the way before it says it fails on the 32MB. Sounds like maybe not… Blancho May 10, 2016 at 12:29 pm Lacie Thunderbolt Drive doing exactly the same. You say one isn't much difference at all, but on the other it's a huge difference.
