    For sometime, I've been seeing a yellow icon enclosing a question mark indicating an "unknown device" in my Device Manager. Today, I noticed a "devicetable" notepad file on my (C) drive desktop that contains numerous identical entries, one of which follows:

    {"Lite-On LTN486 48x Max,Lite-On,LTN486 48x Max,cdrom.drv,DriveNum=4094,YD01,"}
    { drive detected as: Unknown,m_dwDeviceType = 5}
    { Capabilites: Flag1(0x83), Flag2(0xc00200), Flag3(0xa), WriteCDRSpeed(0x0), WriteCDRWSpeed(0x0)}
    Write CDR Speed:
    Write CDRW Speed:
    Device Type : CDROM
    Device Bus Type: ATAPI
    It Supports DAO: N
    It supports SAO: N
    It supports CDText Read: N
    It supports CDText Write: N
    It supports BUFE: N
    It supports BUFE on real write only: N
    It supports DDCD Read: N
    It supports DDCD-R Write: N
    It supports DDCD-R Write and Test: N
    It supports DDCD-RW Write: N
    It supports Raw Read: N
    It supports Raw Write: N

    Are the two issues related? Is it OK to delete the "unknown device" from my Device Mgr? If they are related, will deleting it cause rcognition problems for my CD ROM drive? I'm obviously in over my novice's head. Can someone help?
    Thanx, John Finley.
