DOCUMENT:Q120492 08-AUG-2001 [winnt] TITLE :Periodic Polling Causes Problems with Removable Media PRODUCT :Microsoft Windows NT PROD/VER:3.10 OPER/SYS: KEYWORDS: ====================================================================== 3.10 WINDOWS kbhw kbbug3.10 kbfix3.10.sp3 ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 3.1 - Microsoft Windows NT Workstation version 3.1 - Microsoft Windows NT Advanced Server, version 3.1 ------------------------------------------------------------------------------- SYMPTOMS ======== Removable storage media (for example, CD Juke Box or tapes) may be damaged or get stuck in the drive or changer mechanism. CAUSE ===== In Windows NT 3.1, the Server Service periodically polls all drives for available free space and logs an event if drive space is low. On removable media drives, this polling can cause a conflict with the disk or cartridge drive/changer. If the changer is ejecting the cartridge when a periodic poll is received, the conflict may damage the tape or CD, or jam the tape cartridge or CD in the unit. RESOLUTION ========== To correct this behavior Microsoft has modified the Windows NT Server Service (SRVSVC.DLL) to only poll fixed disks. Removable media, CD-ROMs, and RAM disks are not polled. The new Server Service no longer creates an x$ administrative share (where "x" is the media drive letter) for removable media drives. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem has been corrected in Windows NT Workstation and Windows NT Server version 3.5. This problem has also been corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1.
