PRB: Surprise Removal of SCSI Miniport Controlled Hard Disk Drives on Windows Me May Cause Computer to Stop Responding (328722)


The information in this article applies to:

  • Microsoft Windows Millennium Edition
This article was previously published under Q328722

SYMPTOMS

If you unplug a hard-drive that is attached to a storage controller and then click Refresh in Device Manager, the computer may stop responding. This may occur if the device driver for the controller is a SCSI miniport driver.

CAUSE

This behavior can occur on Windows Millennium Edition because of a conflict between the I/O Supervisor (Ios.vxd) and the disk "SCSI'izer" (Diskvsd.vxd, the program that builds SCSI Request Blocks for I/O requests that are sent to SCSI devices).

MORE INFORMATION

Microsoft Windows 95, Windows 98, Windows 98 Second Edition

Microsoft does not recommend or support surprise removal of any storage device on these Windows operating systems.

Third-party developers frequently create SCSI miniport drivers for non-SCSI storage controllers, such as IDE controllers, for these operating systems. Some of these buses support the concept of surprise device removal, such as the Serial ATA specification.
