An updated Storport storage driver (version 5.2.3790.2497) is available for Windows Server 2003

When you use the Microsoft Storport storage driver for your host bus adaptor (HBA) removable storage device in Windows Server 2003, you may experience one or more of the following symptoms:

• When a program, such as Windows Backup, that uses 16-byte and 6-byte command descriptor blocks issues a command, you receive the following Stop error message:
  STOP 0x0000000A
  IRQL_NOT_LESS_OR_EQUAL
• You receive a Stop error when the Multipath I/O (MPIO) Device Specific Module tries to read a SenseBuffer parameter, and the classPnP layer has not allocated a SenseBuffer parameter.
• You receive a Stop error when two devices appear with the same Plug and Play ID.
• You receive a Stop error when an adaptor is removed and when a timer that is requested by the miniport is not canceled.
• An inquiry page 83 compare operation is not performed correctly. This behavior may cause devices to disappear and then to show differently after another scan. This issue may cause data loss because the writes to the original device may fail.
• On a 64-bit system, page 83 data may present itself incorrectly in an input/output control (IOCTL).
• When a SCSI reservation conflict occurs, an IOCTL pass-through may fail without providing failure status.
