0x00000019 0x0000000000000021 when using readyboost

Hello Cybot.

Thank you for your reply.

Let’s place the computer in clean boot state and check if the issue persists.

Clean boot is a process of starting your computer by using a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your computer performance.

Please refer the Microsoft article below to get more information on this.

How to perform a clean boot in Windows

Please refer the section “How to reset the computer to start normally after clean boot troubleshooting” in the article below and follow the steps to bring your computer to the normal state.

Please reply with the result. We’ll be glad to assist you.

I will setup my system for clean boot in the morning and get back to you

I setup up my system for as clean boot as possible. there were some issues however.

even though I uninstalled MBAM using add/remove programs, it appears it did not uninstall correctly. wheter this is due to a software bug or something else, I do not know. I had to go into the registry and manually remove the MBAMCHAMELEON service entries from HKLM\system\currentcontrolset001\services and HKLM\system\currentcontrolset002\services.

ESET smart security seems to ignore my trying to disable it through msconfig and re-enables it's service entries, and loads at startup.

there is a device in the device manager that is tied to firmware that requires the software be enables for the system to work properly. attempting to use msconfig to disable it, results in multiple entries for the same software that is trying to be disabled (one enabled, one disabled). as a result, aside form eset smart security, the only programs and services that are loading at start up (other than the needed M$ services) are those by Toshiba and three by intel related to the SATA (which is needed because the monitoring system Toshiba setup requires the intel stuff to be enabled to work)

left enabled in services:

Intel(R) Management & Security Application User Notification Service

Intel(R) Management and Security Application Local Management Service

Intel(R) Rapid Storage Technology

NVIDIA Display Driver Service

TOSHIBA eco Utility Service

TOSHIBA HDD Protection Service

TOSHIBA Optical Disc Drive Service

TOSHIBA Power Saver

TOSHIBA Bluetooth Service

TOSHIBA HDD SSD Alert Service

TOSHIBA PC Health Monitor

TOSHIBA Machine Information Service

ConfigFree Service

O2FLASH

ESET Service

I will continue to use my system in this configuration throughout the day until it bsod's on me. would you like me to upload a dump when it does?

Yes, that would be good.

I kept noticing that readyboost keeps turning itself off on the 32Gb device. so I went into computer management\event viewer\applications and services logs\Microsoft\windows\readyboostdriver\operational

and there are a number of the following errors:

A ReadyBoost cache was deleted due to repeated data corruption instances on the associated device that have been detected and handled. While ReadyBoost will always detect and handle these errors, repeated corruption instances may mean that the ReadyBoost device has worn out which reduces its performance. You should consider replacing the ReadyBoost device.

Device name: O2Micro SD #5

Cache path: \Device\HarddiskVolume6\ReadyBoost.sfcache

this is a brand new SD card, and testing says there is no problems sector wise (chkdsk /r)

I am wondering if this error and my 0x19 BSOD problem are related since the error only occurs when I'm using readyboost on the SD card.
