<BLOCKQUOTE><SPAN class=hquote>цитата:</SPAN><HR size=22><SPAN class=quote>SYMPTOMS
If your Windows 2000-based or Windows XP-based computer with multiple ATA drives enters the S1 power state, you may experience one of the following symptoms:
Windows does not recognize the ATA drives when you resume your computer from sleep or standby.
You may receive the following error message:

Unsafe Removal of Device:

You have unplugged or ejected a device without stopping it. Unplugging or ejecting devices without first stopping them can frequently cause your computer to crash and loose valuable data.
Windows may stop responding (hang).
CAUSE
This problem occurs partly because the IDE storage driver stack incorrectly accesses registers that are required for a software reset. This leaves the host controller or device in a hung state. This problem does not affect computers that are using ATA Host controllers that are configured for Legacy mode operation. Although this issue has been identified on the Intel ICH5-based chip set, it is not limited to this hardware.</SPAN><HR size=22></SPAN></BLOCKQUOTE>
