I'm finally operating from a new, fast 2TB disk.

Ever since the migration, I've lost hibernation. I get no error, it just briefly
displays the "Windows is hibernating" screen and then switches back to the desktop
without hibernating.

The hibernation hotfix that I got a year or so again on this newsgroup now doesn't
work because I'm on SP3 (I knew there was a catch to upgrading.)

There is a fixit file here, but I doubt this is going to
fix it, seeing as the computer thought it was going into
Hibernation, and then the file creation step failed.

I'd say there was something wrong with the actual file
operation itself. Like, the Hibernation process wasn't
able to create a file. Is there a hiberfil.sys in there ?
It could be hidden, in terms of file explorer visibility.

If there was an ACPI state issue, you probably wouldn't have
been offered a Hibernate option at all. The option would
have been missing.

If it was the SP2 issue, wouldn't you have seen a dialog
mentioning "Insufficient resources" ? The reason there
wouldn't be a hotfix for SP3, is the replaced files for
the SP2 version, would have been rolled into SP3 so it
already has the fix.

I have a 4GB RAM system, WinXP SP3 32 bit, and the
C:\hiberfil.sys is 3,220,295,680 bytes. My pagefile
is smaller, but since the dump on error is set to
64KB file, that's not a problem. Pagefile just adds
to memory size, in terms of total virtual memory available,
and pagefile doesn't have to match anything otherwise.
Hiberfil.sys has to be able to store the entire RAM image,
in case all the bytes are in use. (The fewer bytes needing
to be written, the faster the Hibernate progress bar
moves during shutdown.)
