A Central Processing Unit (CPU) contains a cache memory system that is primarily used for interfacing with the main memory system. The cache memory system includes two cache memories - Primary and Secondary cache. The Primary cache comprises of SRAM (Static Random Access Memory), while the Secondary Cache comprises of DRAM (Dynamic Random Access Memory). The pages in these cache memories hold the recently-used data and instructions from the memory. Inconsistency or corruption between the pages of primary and secondary data caches result in STOP error message. Two major outcomes that you might encounter after the occurrence of STOP error message are unmountable hard drive and data inaccessibility. An ideal solution to overcome such data loss situations is by restoring the data from the latest backup. But, in case of absence of an updated backup, use advanced data recovery software.
You encounter the below error message while attempting to start your Windows based system:
"STOP: 0x00000055 (parameter 1, parameter 2, parameter 3, parameter 4) DATA_COHERENCY_EXCEPTION"
The four parameters in the above error message differ with computer's configuration.
Data stored in the hard drive becomes inaccessible after the above STOP error message occurs. In addition, you encounter the same error message each time you attempt to start your system.
Cause:
The root cause for the occurrence of above STOP error message is inconsistency between pages in the primary and secondary data caches.
Resolution:
For complete resolution of the above STOP error message, take these measures:
- Remove the new hardware and reboot your system
- Increase the RAM (Random Access Memory) and disk space of your system
- Select Last Known Good Configuration option while rebooting your system. To do so, you need to press F8 when you see "Please select the operating system to start" message at system startup. Next, use arrow keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER
If the STOP error message appears even after taking the above actions, then the best solution is to recover your lost data by using powerful data recovery software. These Data Recovery Tools use effective scanning algorithms to recover lost data from a formatted hard disk. Built with highly interactive user-interface and automated recovery procedure, these data recovery applications are easy to understand and implement.
