Cache reset when waking from sleep or random cache reset please read

reset

On a clean install of the new version the cache lasted about 2 hours, got to 12gb, then it failed:(

I will try to pm slot monsta the log.  On the other hand I’m probably going to rma the thing, since it sets off the raid alarm as well, was waiting to see if patch affected it but i guess not.

For users seeing the cache reset after reboot do you ahve the GUI set to start with windows? I noticed that when my cache is >26GB and the GUI is set to start with boot the cache will sometimes reset. Can anyone else confirm if they are seeing similar issues? If you have EC set to launch the GUI on boot can anyone try disabeling start with windows and see if they see the cache reset? So far in my case if the GUI does not launch with windows the cache reset does not occur.

Is this mean Readcache doesn’ t fast up the Windows boot?

after installing 1.3.2 have not experienced the SLEEP defect …

Hi.

When will this issue be addressed?

SanDisk reply appreciated.

Thanks,

Flavio

Any update on this? There obviously is a problem because myself and others are experiencing it.

Request for fix - again!

Agreed. Some kind of feedback should be posted, even if it is “we are still looking into it”.

well i had no problems on win 7 sp1 but when i switched to win 8 then win 8.1 up1

i had the reset glitch and the 10sec hang…

note i use a old p55ud2 motherboard.

Had another reset yesterday for an unknown reason. Drive wasn’t anywhere near full. I sent my details in and it would help if someone posted an update here.

No idea but I finally got word back from support, my drive has tons of unreadable errors even though it passes their “smart” software scan.  Its a bit funny how they set those thresholds;P

After prodding around the settings for my ReadyCache, I discovered that Windows had set the disk to PIO mode, which obviously has a huge impact on the disk. It’ll reduce it to being slower than the main hard disk, and was disabling disk functions that were probably relied upon by ExpressCache.

After forcing DMA mode on the drive, the problems seem to have been fixed. (If you don’t understand what this is, then you probably shouldn’t risk messign around with it.)

Creztor:   I believe one of my cache resets MAY have been caused by a Windows Update – these are a known possible cause of cache resets.   This update was the late April one where Microsoft fixed the security issue that affected Internet Explorer back to version 6, although other issues may have been addressed as well.     Not sure this was the cause as the cache was fairly full at the time.

NWGuy, I think you are most likely correct about the updates. However, I have had “resets” when no updates were applied. It usually takes about 10 - 20 reboots for it to occur. It’s not the end of the world, BUT if it could be avoided then it would be good. I only use word processing software, so it doesn’t take long to cache that, but it is still just annoying to have it resent every now and then. Again, some kind of word from Sandisk on this would help, especially for those that take the time to submit reports/hardware specs.

Current behavior from my new replacement drive, no full resets, but it seems like prefer dropping back to ~24GB from time to time.  I’m not sure why because it really doesn’t get much past 27GB.

its still like that after more use, i guess its fine, my guess is that it has to keep about that much empty because of write amplification and no over provisioning because its based on a cheaper drive.

Well after a week of testing the new unit, no resets, even on reboot, so if your unit constantly resets even while in use, its hardware failure. Now it works flawlessly go figure.

Both of mine have been running without  reset for over a month now.    I think the varying cache fill we observe is normal operation.

Let’s say I load an application and do some work – those LBA’s rise in access count. perhaps crossing the current caching threshold.   Including them may bring the total cached LBA count up to an 80+% cache fill, at which point the “I’m getting close to full” algorithm will raise the access criteria to be cached, resulting in a reduction of LBA’s cached.    I think this kind of “hysteresis loop” is a normal result of a cache using  integers for read counts.  E.G., going from 50 reads to 51 reads will move some number of LBA’s out of the cache – but then if you go below some percentage, you want to lower your criteria (again by an integer) to keep the cache as full as possible, and some number of LBA’s come in to the cache.   And all this changes constantly with what files we are using day to day.

A variation in fill percentage is the cost of having all the work done for us by algorithms while we watch TV :laughing: .   If we are willing to go to the trouble and expense of moving all the operating system files (or all files) to an SSD, we can get even better performance.  I personally like the tradeoff of minimal effort on my part for a noticable performance increase and extended hard drive life.

Anyone else submit the logs beside me?

Any progress?

ReadyCache is unusable, gets up to about 2 GB then resets to 0.07 when only running the readycache monitor. when with has cacheed some, apps launch very fast, when the cache resets the system is much slower than running without the SSD installed.

I had these problems on Windows 7, butnow I am on Windows 10 and reinstalled the Express Cache Software

What I am facing now is that after 2 reboots the cache resets. So the drive gets to fill around 7 GB and then the cache resets after a restart. The system gets slow after that.

I am creating a systeminfo log and submit it
