* This Delphi code transitions INTO standby/hibernate mode.

* Standby transition (much simpler).

PwrSave is a small component to prevent interruption of program execution due to Windows shutdown, hibernate, standby or user log off. When writing programs for data aqcuisition, control systems or servers these might be very undesired. This component will prevent these events and/or gives you the opportunity to take necessary action when such events occur.

It was my hope that the links I posted would contain enough detail that an advanced Delphi developer would be able to tweak it to be able to glean the HDD status, rather than to just put it to sleep and wake it up.  I'm not that advanced.

--------------------

try this:
* create a relatively small file of data (src.txt)
* execute the following command, either directly, or through a batch file (.bat/.cmd).

copy /v /y src.txt tgt.txt

* check the execution time.  The /v flag should force the operating system to verify that the file has been written to the HDD successfully.
