After the installation of SafeGuard Device Encryption, delayed write failures may be reported by the operating system. This happens right after installing the kernel onto the file system. This may be caused by executing many parallel file I/O operations during the next boot, right after manipulating the file system.
Known to apply to the following Sophos product(s) and version(s)
SafeGuard Device Encryption as of version 5.40
All supported operating systems
Windows XP SP2, SP3
What To Do
An alternative way to install the SafeGuard Device Encryption Kernel, which avoids delayed write errors, can be forced by adding the following registry value:

This registry value must be added before executing the SafeGuard Device Encryption setup.
