DOCUMENT:Q132770 17-DEC-2000 [win95x] TITLE :Duplicate SCSI Device Entries Appear in Device Manager PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:95 OPER/SYS: KEYWORDS:win95 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== Duplicate SCSI device entries appear in Device Manager, and many unexplained drive letters appear in Windows Explorer or My Computer. CAUSE ===== A SCSI device is installed that has the same device ID of 2, 7, or 15 as another SCSI device detected on the computer. Duplicate SCSI device entries appear in Device Manager when a SCSI device with an ID of 7 or 15 is put on the same SCSI ID as the SCSI controller. SCSI controllers are typically on SCSI ID 7 or ID 15 (on a wide SCSI interface). If a SCSI device detects another device on ID 2, it usually means that two SCSI controllers are using the same chain on ID 2. RESOLUTION ========== If a SCSI device conflicts with another SCSI device on ID 7 or ID 15 (on a wide SCSI interface), change the SCSI ID of the duplicated SCSI device to an unused ID, such as 3, 4, 5, or 6. If two SCSI controllers conflict with each other on ID 2, break the chain. For example, make sure the internal cable goes only to the internal device (or devices), not to a PCI card.
