Laptop and Windows 10 Power Saving features maybe causing SSD to randomly lock up.
Posted on 2016-10-14
I have an old laptop from around 2009. Years ago I had replaced it's old usata SSD for a smaller, cheaper, faster, more advanced msata ssd using one of those adapter cards. Under Windows 7, 8.0 and 8.1 and even the first builds of 10, I never had any issues with it.
But at some point, I can't remember exactly when (about a year ago) I started to get what appeared to be SSD lock ups. IE the computer would stay up and the mouse movable but everything else would freeze. It was like anything that was in RAM I could sort of interact with.
Times when I had task manager already open and the system started to stall, I would switch over to task manager, and I could see the RAM and the CPU were active, but the HD activity went to 100%, but with 0 reads and writes. Eventually it would plateau and settle again. I would check event logs to see what was going on and I would see events regarding the disk not responding for such and such amount of time.
So I figured the drive had and issue, bought another one (an iteration of the same brand) and same issue. There doesn't seem to be any reason or rhyme to when the lockout will start, but they are annoyingly frequent and occur waaay waaay less when the laptop is on adapter power as apposed to battery.
So I am thinking it is some behind the scenes power saving feature of Windows 10 that may not like or be able to translate its commands over the usata to msata interface.
Things I have done to troubleshoot, which did not work.
1. Put power profile to high performance mode and check that disk never sleeps for both on power and battery modes.
2. Disable some sort of disk caching thing (I can't remember the term) that was in disk properties. This was out of desperation really.
3. Try to mess around with the LPM registry settings suggestions that some forums posted for Windows 7 walk through, that don't at all translate to Windows 10 registry structure. So sort of useless.
4. Tried to switch from AHCI to IDE, though there is no proper walk through on how to do this via the registry on windows 10 (only 7 and sort of 8). Then the BIOS switch.
5. This is not an Intel ssd so there are no special software to manage this drive. It's by some brand called mydigitalssd.
6. Put in the dishwasher long cycle with bleach and nothing, just removed some of the anodized black paint.
I am hoping someone can lend me some insight.
Thanks for your help.
