Sometimes CD/DVD rom drive doesnt work...?

pls cheak the wire of cd& dvd that are not tight my advise is that to change the wire of the cd drive

Start > Control Panel > System > Hardware tab > Device Manager Expand "IDE ATA/ATAPI controllers" and look under SECONDARY IDE CHANNEL Right click Secondary and select Properties, Advanced Settings tab Under this tab you should see two box's. DEVICE 0 and DEVICE 1 NOTE: DEVICE 1 under CURRENT TRANSFER MODE might state it does not apply. If so, ignore it, if it does not state that it is not in use, then do the same for DEVICE 1 as you do for DEVICE 0 In Device 0 it should read out as following, there should not be anything stating PIO unless your computer is fairly old (like... 1999 or older.. it varies): --------------------------------------... DEVICE TYPE: Auto Detection Transfer Mode: DMA if available Current Transfer Mode: Ultra DMA Mode 5 --------------------------------------... Now, Current Transfer Mode can say something different. EX: Mode 1 is a slower form, and Mode 5 is very fast as in Ultra Quick. So it may display something a bit different, as long as it states it is in DMA mode it should be alright. Also, it may say something like.. "Multi-Word DMA Mode 2" IF TRANSFER MODE: "PIO Only" switch that over to "DMA if available" and restart your computer. Once restarted, come back in and continue the checks from this point ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~... IF ----------------------------- TRANSFER MODE: "DMA if available" Current Transfer Mode: PIO Mode ----------------------------- Then we have a problem, if this is TRUE, then click on the Driver Tab in this window at the top. From here, Uninstall Drivers. It will give you a warning, no worries, continue on. Once you restart your computer it will automatically detect the devices and reinstall everything for you. Once done, try playing your DVD and see if it works. If not, go back in and make sure everything is the way it should be.

your drive my not be in tight take it out and push it back in then it will show up

change the DATA CABLE (IDE CABLE)
