SYMPTOMS
When you put a Windows Vista-based computer in hibernation, Windows Vista may stop responding (hang). Additionally, you may receive a Stop error message that resembles the following:

STOP: 0x000000A0 (0x00000009, 0xc0000001, 0x00000001, 0x00000000)

INTERNAL_POWER_ERROR (a0)

Arg1: 00000009, A fatal error occurred while preparing the hibernate file.

Arg2: c0000001, Status code

Arg3: 00000001, Mirroring phase

Arg4: 00000000

This issue occurs if the computer has Intel 82801G ICH7-M Serial ATA storage controllers that are connected to the 2.5-inch hard disks.



CAUSE
This issue occurs because of an error in the Atapi.sys file. Before Windows Vista enters hibernation, Windows Vista has to write the memory to the hibernation file on the disk. However, in some cases, the storage drive may not return the correct value when system tries to initialize the corresponding storage stack. When the storage drive returns an incorrect value, Windows Vista stops responding.
