    I know it's a driver. What sort of message did you get Gwyneth?

    SCSI (pronounced "scuzzy") is an older-type connection--although still used here and there.

    As in, SCSI drive, SCSI CD, etc. A lot of external devices used to be SCSI. Nowadays, it's surprising if you see any.

    To sound smart, do pronounce it confidently as "scuzzy" as mentioned by Don.

    The following is a quote from: www.datapro.net/scsi_doc.html. I know this stuff, but I don't think about it as often as others do, so they can say it better.

    My comments.

    SCSI is very expensive.
    SCSI can be very fast.
    SCSI is very efficient.

    Business servers are almost exclusively SCSI. The servers that I work with have SCSI hard drives, SCSI tape drives and SCSI CD-ROMS.

    Most home computers use EIDE (enhanced Integrated Drive Electronics) Hard Drives and CD-ROMS.

    Compared to SCSI
    EIDE is typically much cheaper than SCSI.
    EIDE is typically slower except for the newest and most cutting edge EIDE technology. Then EIDE gets a little expensive, but still cheaper than SCSI.
    EIDE is not as efficient as SCSI.

    Rough estimate. A 9 Gigabyte SCSI Hard drive can cost approximately $800. A 9 Gigabyte EIDE hard drive would cost pennies compared to that.

    If I could afford it, all my storage devices, Hard drives, CD-ROMS, etc. would be SCSI. I have a scanner that could be connected to a SCSI card. But it also has a USB connection that works very well. As a result I would not use SCSI for my scanner.

    I try to buy the most current EIDE stuff. As far as I know, it seems like the newest SCSI technology will always beat the newest EIDE technology. But EIDE will always be cheaper.

    I have one of the newest EIDE hard drives in my machine at home. To my surprise the chip on the mother board sort of thinks it is a SCSI device. I loaded the proper EIDE drivers and it works just fine.

    Dave.

    Additionally,

    One EIDE controller is limited to a total of 4 devices each being accessed one at a time.

    One SCSI controller can support up to 16 devices, each being accessed simultaneously.

    This is a very big difference.

    the DVD player which is on this computer..... won`t go, and in the control panel&gt;system&gt;device manager CD rom&gt; properties window I have 3 boxes to check/uncheck
    1 disconnect
    2 sync data transfer
    3 Auto insert notification

    when I use ? to find out what these boxes mean the say - these are for SCSI devices and should not be changed if device is working :-( ....... I think I may have changed by mistake, does any one know what I should have checked?
