A transaction log recovery process on a partition in a Windows Embedded CE 6.0 R3-based device may fail after a power loss event occurs

Assume that you have Windows Embedded CE 6.0 R3-based device that contains a flash partition. In this situation, a transaction log recovery process on the partition may fail after a power loss event occurs on the device. After this issue occurs, the partition cannot be mounted or you experience a data loss event on the partition.

During the startup process, the transaction log recovery process runs before the file system on the flash partition is mounted. The transaction log consists of a list of log entries. The log entries are organized into groups of flash blocks in the partition. However, log entries in one of the flash blocks may be invalid after a power loss event. Therefore, the transaction log recovery process fails when the flash abstraction layer scans the invalid log entries.
