We don't actually attempt to correct the problem, we say we are forcing a retry, but our method of forcing a retry is to simply return DID_RETRY_COMMAND to the mid level scsi code and let it do what it wants. We assume it will return an error elsewhere when the time comes. -- ***************************************************************************** * Doug Ledford * Unix, Novell, Dos, Windows 3.x, * * dledford@dialnet.net 873-DIAL * WfW, Windows 95 & NT Technician * * PPP access $14.95/month ***************************************** * Springfield, MO and surrounding * Usenet news, e-mail and shell account.* * communities.
