No Meeting This Week

           

Special Notice

            Are you getting tired of reading this message about the library replacing the carpeting – well, guess what – here’s another message.  The library has canceled the use of the auditorium until June 12th.

 

Installing a Hard Drive

(Info from Smart Computing June 2002)

            On the back of the hard rive you will see a power receptacle, a port for the IDE cable, and a bunch of metal pins with one or more tiny pieces of plastic on them.  Those pins are jumpers, and you use the plastic pieces to connect two pins and set the drive in a particular mode, depending on the duty you expect to perform.  Unless you plan to use two hard drives, you’ll usually want to position the jumpers so the drive is in master mode.  If you add another hard drive or other device (like a CD drive), you will usually set it to slave when it is on the same IDE cable.

            CS (cable select) mode is the exception to the standard master/slave drive configurations.  It requires a special CS IDE cable and a proper motherboard configuration to recognize CS devices (some motherboards don’t).  In this mode, you set both devices attached to the same IDE cable in CS mode and the computer will automatically detect which device is primary and which is secondary by its position on the cable.  The one on the far end of the cable is the primary device, and the one in the middle is the secondary device.  You can use the traditional master/slave settings on a CS cable, so when you are in doubt, always set the primary drive to master and the secondary device to slave.

            It is not recommended to attach your CD drive to the same IDE cable as your hard drive because an IDE controllers let the slowest drive on the cable determine the maximum speed at which the other device can operate.  Modern hard drives have transfer rates several times faster than those of CD-ROM or DVD-ROM drives, so you can hurt hard drive performance by sharing the IDE cable with a CD-ROM drive.

 

**** But remember the article we included in the handout dated 20020220 --

 

            “It looks like both your source and your destination drive for the “on the fly” copy process are connected to the same IDE bus.  We would strongly recommend to connect your source and the destination drive to different IDE busses.  An IDE bus cannot handle interleaved read and write commands.  This will reduce the data transfer rate during “on the fly” copies and may therefore cause a buffer under run error”.  It is suggested that you add your CD writer as the SLAVE on the PRIMARY buss after the hard drive.

Health Hoaxes

            Because people are spreading false rumors about health-related subjects with such great ease via email, use this site to check on your health related email to see if it is a hoax before forwarding it on to someone else.

            This web page is for the Center for Disease Control and Prevention and now has a page devoted to Health Related Hoaxes and Rumors.  The web address is

Changing the File Association

            You double-click on a file and it can’t find the program associated with it – or you would like to change which program is associated with it – try this…..

            In Windows Me and Windows XP – from the START menu, choose SEARCH.  Type in  *.JPG  or *.GIF  or whatever extension you wish to change the file association of.  When files of this type have been located, right click on one of them and choose OPEN WITH from the menu.  Now click on CHOOSE PROGRAM.  This will list all executable programs found in the Windows Registry.  It helps to know which program(s) would open the type of file that you are working with.  Highlight the program – put a check mark in the ALWAYS USE THIS PROGRAM TO OPEN THESE FILES box and click OK.
