Windows 10 Anniversary - freezing/pausing

Yesterday, I upgraded three systems - one i7 desktop and two i7 notebooks - to Windows 10 Anniversary (from Windows 10, which were previously upgraded from Windows 7).  Silly me - as I was low on disk space afterwards, I did the disk cleanup and deleted all the old versions and install files. 

The i7 desktop started freezing up a lot - I checked the system logs and saw lots of I/O timeouts on the disk subsystem (Patriot Ignite 480GB SSD).  I rebooted, it seemed OK, so I downloaded the Patriot disk utility and updated the drive's firmware.  The drive toasted - the system won't boot, etc.  I'm trying to see if I can get Patriot Memory to replace the drive.

One of the notebooks (am writing this on) is an HP 2540p - i7 2.13GHz, 8GB RAM, Crucial C300 256GB SSD - have noticed pausing on as well.  Checked the system logs - see several instances of disk timeout, retries, and resets here as well. 

Log Name:      System
Source:        disk

The IO operation at logical block address 0x11f64b30 for Disk 0 (PDO name: \Device\00000037) was retried.

Log Name:      System
Source:        storahci

Reset to device, \Device\RaidPort0, was issued.

I contacted Microsoft - they basically gave me the link to create the .ISO file (they claim it's the Anniversary edition, but I don't know yet) and said I could use my existing Win7 or later keys to activate Win10.  Never mind all the lost time or data, nor the toasted SSD (my fault, I suppose) involved. 

Based on what I am seeing on these two systems (third is same notebook as second, but with Intel X-18 160GB SSD vs the Crucial in this one - and I haven't checked it yet) - I would not advise anyone I know to do the update to Windows 10 Anniversary edition until this issue is understood/resolved. 

I'm also (one of the few) with Windows Phone 10 (Nokia Lumia Icon) - doubt I'll be updating it to the Anniversary edition any time soon.

Hi Wulf,

It's perfect!

The annoying storahci is completely suppressed on my machine.

For others' information, configuration of my machine is,

- CPU: AMD FX8350

- M/B: M5A97 PRO


Thanks again, and I hope it'll be fixed on next update.



Trying this now and will report here the outcome.


Kudos to wulf_xyz for this!   I have a Sandisk SDSSDA240G solid-state drive that was working fine in Windows 10 Fall Update Build 1511 and had the same symptoms as everyone else once the Anniversary Update build 1607 installed. Making the NoLPM registry change described by wulf_xyz fixed the problems with my system freezing and blue-screening.  The system event log was filled with the following errors prior to the registry change.

The IO Operation at logical block address 0x4aa4c68 for Disk 0 (PDO name: \Device\00000037) was retried

Reset to device, \Device\RaidPort0, was issued.

I had the same issue with a crucial c300 and the windows 10 anniversary update. It looks like the crucial c300 has an issue with LPM (link power management; just google for "crucial c300 lpm") that can be resolved if you turn off the LPM for the c300.

This is what I have done to resolve the issue. I am assuming you are still using the MS driver and not the Intel one:

1. open regedit.exe

1a. export HKLM\SYSTEM\CurrentControlSet\Services\storahci\ (in case something goes wrong...)

2. go to HKLM\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device

3. locate the key with the name "NoLPM" (of type REG_MULTI_SZ)

4. double click on the key. This key will already have some entries (I got 8)

5. add a new line with the text "C300-CTFDDAC128MAG*" (without the quotes). The text C300-CTFDDAC128MAG must match what you see in the device manager as the name of your disk. Since you have a 256 GB disk this text will be different (maybe CTFDDAC256MAG?)

6. close regedit

7. reboot windows

8. enjoy :)

This is just unbelievable how incompetent MS is. The problem is still not fixed. I got a Venue 11 Pro 7140 which has the issue. Freezes when resuming from sleep, bluescreens in sleep. Log full of disk errors.

Deactivating LPM is NOT AN OPTION. At least not on a tablet... it will cause a permanent ~2400mWh drain and suck your battery empty in a few hours and keep your tablet warm.
