The c/drive is off. How do I turn it back on?

To fix this problem u must first turn of your xbox, turn it back on, open the cd drive, turn it off making sure it does not close, turn it back on, close the drive, and restart you xbox

Hello,

Okay, shut down your laptop, turn it up side down, remove laptop battery, remove Cd drive by first unscrewing the CD drive's screw before removing/detaching the Cd drive from the computer.

Turn on your computer without the Cd/drive, allow computer to boot, after a while, shut down computer, fix in back the CD drive and turn the system back on.

By now the system should read the CD drive. If it does not, then I'm afraid some this is wrong with the Drive, but I'm sure it should work.

Take care.

the disk is not being spun more than likely. thats why i always get open tray. wat u need to do is this
1) unplug it all and take it apart
2) get to the disk drive
3)unscrew the 4 screws on the SIDES onf the drive. not the 2 in the middle 4)take off the cover GENTLY
5)put the drive back intoplace without the top on it
6)plug it up and turn it on
7) observe the disk want to spin but it wont. there is not enough pressure to get it going, wat u need to do it give it a little "push-start" spin it while applying pressure. it may take a few trys to get the disk going fast. it will need to start going very fast.
8) when it does that, quickly place the top back onto the drive without screwing it back on.
it should contunie to spin. turn it off, unplug it, screw the top back onto the drive, then reassemble the 360. works for me EVERy time

Turn off system, take hard drive off, put hard drive back on, turn system back on.

GO TO DEVICE MANAGER AND SEE IF THE DRIVE IS WORKING.IT MOST LIKELY IS SO TURN POWER OF PC OPEN THE SHELL ON PROSESSER AND TAKE DISC OUT,KNOW BEFORE YOU PUT SHELL BACK ON TURN POWER BACK ON DO NOT TOUCH ANYTHING EXCEPT THE DRIVE SEE IF IT OPENS OR CLOSES.IF IT DOES NOT,SHUT POWER OFF AND UNPLUG DRIVE THEN PLUG IT BACK IN.PUT SHELL BACK ON AND SEE IF DRIVE OPENS.IF NOT THE DRIVES FAULTY...HOPE THIS HELPS

Universal joint is shot, needs to be replaced right away.

You need to turn the raid back on and go into the raid utility. Once in the raid utility u should see a function to Break or Delete the raid group. Do this and then the drive should revert to a non-member disk and therefore a single drive. Once this is done u can turn the raid off again.

Try turning everything off and then replugging the drive in.  Then start your computer back up/turn drive back on (if you have to).

This might be due to a registry problem. Re-installing windows (OS) or repairing your OS installation can help. You can install from any previous back up or get the installation files in a USB storage device like pen drive.
You can also try the following which have worked .. insert the OS installation disk in the cd-dvd drive. restart Pc. change boot device option. installation of new OS begins. this is a hit n trial method, but has worked earlier.
