Question about HP Compaq dc7100 PC Desktop

Won't reconize DVD burner

I picked up a DC7100 tower and it came with a CD/DVD rom drive. It seems to have a ribbon cable that would able me to add a second drive. I have a DVD burner and wanted to add it to the HP but it doesn't reconize it after hardware install... I installed it first thing when I got the computer and it did not even reconize the CD rom that came with it. I had to go into F10 and config the CD drive there. There was no DVD burner drive there in the setup. Maybe I need to do one at a time, I don't know.

Also want to add a hard drive and believe I can with the full size tower. 40 gig original drive is way to small, but my second hard drive from my older computer hooks up differant, with a ribbon cable... More than likely it means new drive as I would like it internal.
Thank you in advance. Rob

Well, the CD ribon cable goes into the IDE 2 slot on the Mainboard and the furthest connector on the other end is the master, the second one closest to the board is the Slave connector. The CD drive has a jumper on the back between where the ribbon and the power connector go, on the case some where it should have a diagram showing the jumper setting to put it in as master or slave. Set it accordingly.

Same with Hard drives.

If the Hard drive has a diferent Cable like a SATA, then be sure to get a SATA as the new one.

Now the IDE cables may be bad check them for damage just to be on the safe side.

My CD-rom will not work after inserting CD's or DVD will not rev-up what wrong and what should I Do I Have Inspiron 531????


1.The laser optical eye of the CD-ROM drive may be dirty, and needs cleaning.
If the optical eye is dirty, it won't read the information on the disk you install.

A) Computer on, Windows loaded, open the tray of the DVD-ROM drive. (Or DVD burner drive. Whichever drive you are referring to. DVD-R/RW)
Shut the computer down normally. (Start>Turn Off Computer>Shut Down)

Unplug the computer from power.
Use a can of compressed air fror computers, and spray air into the DVD-ROM drive.

The optical eye, is located on the bottom of the DVD-ROM drive. (Or burner drive)
The opening in the bottom of the tray, that comes out for your disk, is where you spray the air.

You won't be able to see the optical eye, so how will you know you are spraying the air at the correct place?

If you start at the front of the bottom of the DVD-ROM drive, and work your way towards the back, you will clean the optical eye. Spray across from side to side, and in rows, as you proceed towards the rear.

(Air will make it's way through, and reach the optical eye. The optical eye is not visible, as it can be harmful to the human eye when operating.
Laser.
When the tray is closed the optical eye is exposed. It is not exposed to where it can harm the computer user.

More information that may be helpful, in understanding where the optical eye is located,

2.Make Windows reinstall the drivers.
This solution requires physically removing the flat ribbon cable from the back of the DVD-ROM/DVD burner drive, then reattaching it.

Software advice of Updating the drivers, Rollback the drivers, or downloading, and installing the drivers, doesn't always work, or doesn't work.

If the physical solutions I am providing here does not work, we will proceed to the software solutions if you wish. (Comment)

Hi. I need to purchase a DVD burner for my Compaq dc7100 and need to know what brands will fit my computer. Thanks, **** P


I've checked on the specs of dc7100, and it shows that it has multibay optional for 12.7mm removable drives .

I've difficulties finding the exact DVD compatible for dc7100 since it seems that it's already been discontinued.

However, these are the closest match that I've found. Kindly click to double check the specification if it matches your computer:

Removing current cd/dvd burner from tower to replace with new one can't seem to get it out.acer tower, not real smart with computers sorry


most CDRW drives are secured using 4 screws (2 on each side) which means you have to remove both side plates of the tower to remove the drive, sometimes manufacturers use rails which "clip" the drive in place and are removed via the front instead (sometimes having to remove a retaining screw).

after that the drive is only held in place by the connected cables.

Cd/dvd dosen work pleace geimy a solution


Hi,
i cant get you. cd/dvd is not working or cd/dvd rom drive is not working ? To work cd/dvd rom drive properly, Make sure the Jumper settings of the drive is set to slave or else remove all the jumpers from the cd/dvd rom drive, it automatically sets to slave. Check the power cable and the FRC(flat ribbon cable) of the cd/dvd rom drive. Hopefully it should work. Thank you.

I went to go burn a cd and it said that i have no cd burner on my computer but i know that i do, but my computer wont even play a dvd or a game, i think i might of accidentally uninstalled my cd drive, is...


Hi

Ok First to ensure that your CD-Rom / DVD is installed correctly

Goto the control panel if you can see a whole list of icons find and click on system

otherwise find Performance and maintenance and then click on system

now up the top of this new window find and click the hardware tab

finally click on the Device Manager button , this will bring up the Device manager window


in this window look for and expand by clicking the plus Icon next to DVD/CD-ROM Drives

if you see anything in here your CD drive is installed. You will probably find that either you optical drive is either disconnected and the ribbon cable connecting it to the motherboard will need to be checked , or you have got a faulty optical drive

If you cant see anything in here go back to the control panel and find add hardware if you cant see that icon click on printers and other hardware and in the left hand side bar click on add hardware.

This will bring up a step by step wizard

after clicking next on the initial screen windows will do a scan and try and detect any hardware devices that have not been installed yet. If on the next screen you are asked "Have you connected the hardware?" please open up your PC and check the ribbon connection on the reverse of the optical drive and make sure the power connectors etc are properly seated.

If this works follow the on screen steps and installation will be straight forward.

Hopefully this will solve your problems

Cheers.

If you have any other queries please respond

Thankyou
