PRB: DCB_unit_number Field Not Filled in for Removable Drives

 * }

Q141266

-

The information in this article applies to:


 * Microsoft Win32 Device Driver Kit (DDK) Windows 95

-

SYMPTOMS
DCBs used by Input Output Superviosor (IOS) layer drivers representing removable disk drives do not fill in the appropriate drive number in the DCB_unit_number field of the DCB.

RESOLUTION
Instead of using the DCB_unit_number field of the DCB, use the DCB in the DCB_next_logical_dcb field in the physical DCB. The drive letter can be obtained from the DCB_drive_ltr_equiv field in this DCB.

STATUS
This behavior is by design.
