Unexpected Shutdowns in xpe

[Guest]

Hello

I have the following Problem. I have a flash disk and ewf disk overlay.
Now i turned off the enable write caching on flash.
But it seems to cache the datas. For example, when i copy a file and
paste it and then after about 5seconds i turn off my pc and turn on again, the
copyed file isn't on the flash. when i wait a longer time ( about a minute )
the file is copied.
Now how can i solve this problem?

greetings

sam,

Didn't you find the workaround yourself? You mentioned that you turned off the Write Caching on flash. That should help.

sam,

If you have EWF on and the Write Caching is Off, I can't think of problems with the software. However, it is known that not all
hardware supports this write-through capability. So, your flash firmware may be preventing the disable the cache. (or there may be
an internal firmware cache)

You can do a quick test. Try to create a file with Win32 API (CreateFile) and pass the FILE_FLAG_WRITE_THROUGH flag there (this will
instruct the system to write through any intermediate cache and go directly to disk). Write and close the file. Then reboot (or
shutdown) in a few seconds or minutes and see if the file got saved persistently.
If not, you will have to either switch to another hardware or upgrade the firmware on your current flash if available.
