There is more going on here than you realize. Once a new disk (with a new disk signature) is installed on a W2K system, the Disk Manager will attempt to remove it, meaning that your bus driver will receive IRP_MN_QUERY_REMOVE and IRP_MN_REMOVE PnP Irps. This is so that the storage device stack can be rebuilt properly. Therefore, when your PDO receives the IRP_MN_REMOVE, you must not deleted your PDO. Just clear the claimed flag and reset your PNP device state to NotStarted. Eventually your PDO will receive another IRP_MN_START_DEVICE. -----Original Message----- From: anton_kolomyeytsev@hotmail.com [mailto:anton_kolomyeytsev@hotmail.com] Sent: Tuesday, July 03, 2001 3:55 AM To: NT Developers Interest List Subject: [ntdev] Re: Virtual disk with a bus enumerator (SRB_FUNCTION_CLAIM_DEVICE) ? Hi, You have to implement a couple of IOCTLs in your code as well. At least IOCTL_STORAGE_QUERY_PROPERTY. See the source of the disk class driver in DDK for this. Other IOCTLs are optional (as IOCTL_SCSI_GET_ADDRESS, IOCTL_DISK_GET_DRIVE_GEOMETRY etc).
