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.

More information

Windows ATA and ATAPI drivers may experience these symptoms, and any driver controller chip set that runs in native IDE mode may also be affected.

Native mode ATA controllers are not common, and are generally used only on newer systems with multiple ATA controllers. For example, these might be used with a combination of Parallel ATA and Serial ATA (SATA) controllers.

To determine if your computer is running in ATA Native mode:
  1. Right-click My Computer, and then click Properties.
  2. Click the Hardware tab, and then click Device Manager.
  3. On the View menu, click Resources by Type.
  4. Expand Interrupt Request (IRQ).
If Device Manager shows that IRQ 14 is assigned to the primary IDE channel and it shows that IRQ 15 is assigned to the secondary IDE channel, your computer is in Compatibility mode.

If only one of these IRQs (14, 15) is assigned to an IDE channel and both channels are enabled in your computer BIOS, your computer is in Native mode.

Many computers that are equipped with Native mode ATA controllers also have a setting in the BIOS to enable or disable Native mode.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft Windows XP Service Pack 2. This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
