Storport delays PnP removal of a device in Windows 8.1 or Windows Server 2012 R2

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 EssentialsWindows Server 2012 R2 Standard

It may take longer than expected (30 to 200 seconds) for PnP (Plug and Play) to remove a disk drive that fails or is no longer attached to your operating system.

Cause


This issue occurs because Storport inspects a stale ScsiStatus field in the SCSI_REQUEST_BLOCK (SRB) to retry I/O requests. This occurs even if the miniport sets the SrbStatus field to SRB_STATUS_SELECTION_TIMEOUT that indicates the device is no longer present.

Resolution


The hotfix makes sure that Storport correctly interprets the SrbStatus. To obtain this update, install the November 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2.

Status


Microsoft has confirmed that this is an update for the Microsoft products that are listed in the "Applies to" section.
