When you try to write data to a Serial Bus Protocol 2 (SBP-2) device, such as an IEEE (Institute of Electrical and Electronics Engineers) 1394 drive, you may experience one or more of the following symptoms:
- The drive stops responding.
- The drive disappears from My Computer.
- When you view the drive in Device Manager, an exclamation point in a yellow circle may be displayed for the drive. When you view the properties of the drive, the status for the device may report Code 43. This status code indicates that Windows has stopped the device because the device has reported problems.
- The access light for the drive stays on.
- Events that are similar to the following may be logged in the System log:
The device, Device_name, did not respond within the timeout period.
An error was detected on device \Device\Harddisk1\D during a paging operation.
The system failed to flush data to the transaction log.
Corruption may occur.
Application popup: Windows - Delayed Write Failed: Windows was unable to save all the data for the file File_path\File_name. The data has been lost. This error may be caused by a failure of your computer hardware or network connection.
Please try to save this file elsewhere.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
SBP-2 is an implementation of the ANSI SBP-2 specification that is used to encapsulate small computer system interface (SCSI) requests over an IEEE 1394 bus. The protocol provides support for IEEE 1394 printers, CD-ROMs, DVDs, scanners, and storage devices. With Microsoft Windows 2000 and Windows XP, support for IEEE 1394 storage devices, CD-ROMs, DVDs, printers, and scanners is available through the SBP-2 port driver.
